What Is A Radio Transmitter

A radio transmitter is a handheld device that pilots use to control their FPV drone in flight. It sends signals to the drone’s receiver, then the flight controller which translates those signals into drone movement.

radio transmitter receiver protocol

The transmitter is a crucial piece of equipment for flying FPV drones because it allows the pilot to control the drone’s movements with precision and accuracy. A high-quality transmitter with a reliable connection is essential for ensuring that the drone responds quickly and accurately to the pilot’s inputs. A comfortable grip and responsive sticks are important for a good piloting experience.

Some transmitters offer advanced features like customizable settings, telemetry data, and support for different protocols and receivers, allowing pilots to tailor their flying experience to their preferences and needs.

When you start flying FPV, buying a radio transmitter should be one of your first purchases. With it, you can practice flying in a simulator even before owning a drone. A good transmitter will last you a long time, unlike other accessories that may break or become outdated quickly. So, it’s worth investing a bit more in a high-quality transmitter.

Radio Firmware

The radio firmware is like the operating system of the radio – like Windows for computers. It serves as the interface that allows you to interact with the radio and control your drone.

Currently, EdgeTX is the go-to firmware. As long as the radio comes with EdgeTX, you are good to go. It’s open source and has a large user base. Most radio transmitters on the market support EdgeTX and come with it pre-installed, making it easy to transfer your settings to a new radio when you upgrade. EdgeTX is highly configurable and offers support for many different types of aircraft. While it may have a steep learning curve for beginners, the knowledge gained from using it will be invaluable in the long run.

While OpenTX used to be a popular firmware, it has fallen behind EdgeTX in terms of features and capabilities. Other firmware options include FreedomTX, which is based on OpenTX and is used in TBS Tango 2 and Mambo, as well as Frsky’s latest radios which use ETHOS. But these firmware are specific to certain radios.

Radio Link Protocols

Jumper T Pro Radio Transmitter Install Expresslrs Elrs Tx Module

Before picking up a radio, it’s important to consider which radio link you want to use. The most popular systems used in FPV drones today include:

It’s recommended to stick with a popular radio link to ensure you have access to online help and better resale value.

ExpressLRS and Crossfire are undoubtedly the most popular radio links at the moment, and these are the two I would recommend in 2024. ExpressLRS is known for its affordability, high performance, open source nature, and cutting-edge features. On the other hand, Crossfire is known for its reliability and user-friendly configuration. It’s worth noting that ExpressLRS hardware is usually a lot more affordable and feature-rich compared to other proprietary radio systems because it is open source and the development is driven by the community. Personally I prefer ExpressLRS, see this post for all the reasons why I like it.

Some radios come with the radio link built-in, while others have an external module bay that can be used to install an external module. Having an external module bay gives you more flexibility when choosing a radio link.

Once you’ve decided on which radio link you want to use, your radio choices will be narrowed down significantly.

Form Factor

Betafpv Literadio 3 Pro Radio Transmitter Hand Hold Grip Thumber Ergonomics

When it comes to radio transmitters, there are two main styles: full size and gamepad style. Gamepad style radios are very compact but tend to have fewer features, such as less battery capacity, smaller gimbals, fewer switches, and smaller screens. This can make them less comfortable to hold, especially for those with larger hands or who prefer “pinching” the sticks.

Radiomaster Tx16s Mark Ii Mkii Radio Transmitter

On the other hand, if size is not an issue, a full size radio may be the more versatile option. Full size radios generally have ergonomics that works for a wider range of people, and the standard size gimbals provide better resolution and precision. Ultimately, the choice comes down to personal preference and what feels most comfortable for the individual pilot.


Radiomaster Boxer Radio Transmitter Fingers Hold Pinch Hand

It’s true that evaluating the ergonomics of a radio transmitter can be challenging when buying online. However, it’s still an important factor to consider as comfort and control are crucial for flying FPV drones.

Apart from radio size, the design of the radio is also important, and factors such as hand grip, the presence of a lanyard loop, and the location and types of switches should be considered. The weight of the transmitter is another factor to take into account, as a heavier radio may cause fatigue over time, while a lighter one may feel less substantial to control the drone accurately.

While reputable manufacturers are likely to consider ergonomics when designing their transmitters, there’s still a wide range of variation in terms of grip, switch placement, and weight distribution etc.

Attending local meetups and trying different radios from other pilots can be a great way to get a feel for what works for you. Alternatively, you can also read reviews and watch videos from trusted sources to get an idea of the ergonomics of different radio models before making a purchase.


radio transmitter gimbals

The two sticks on a radio are called gimbals, and they are responsible for controlling the movement of your drone. As a pilot, you use the gimbals to give commands to your drone, such as:

  • Throttle: You control the speed of the motors, which affects the drone’s overall speed.
  • Pitch (Elevator): This command makes the drone rotate along its lateral axis, moving it forward or backward.
  • Roll (Aileron): This command makes the drone rotate along its longitudinal axis, moving it left or right.
  • Yaw (Rudder): This command makes the drone rotate along its vertical axis, turning it left or right.

Here’s is an animated demonstration of how the drone react to each stick movement:

Gimbal Types

When it comes to gimbals, there are two main types to consider: Potentiometer and Hall Sensor.

Potentiometer based gimbals are less expensive, but they wear out faster due to physical contacts in brush joints causing friction. On the other hand, Hall Sensor gimbals use magnets to determine the stick position and therefore are more durable.

Potentiometer Gimbal

Hall Gimbal

Hall Gimbal

Apart from increased longevity, Hall Sensor gimbals also offer better accuracy and resolution with reduced jittering. Some even claim hall gimbals are smoother but that sometimes can be subjective. While beginners may not notice a huge difference in gimbal quality, it becomes an important consideration as you grow as a pilot.

Regardless of the type of gimbals, you can usually adjust the spring tension to achieve a preferred stick feel. This is often a matter of personal preference, and it can have a significant impact on your control precision.

There are two gimbal sizes: full size gimbals and mini gimbals. Full size gimbals are larger and give you better precision due to the longer stick travel while mini gimbals are more compact. You tend to find full size gimbals in full size radios, and mini gimbals in gamepad style radios.


Radio Transmitter Gimbals Mode 1 2 3 4 Roll Pitch Yaw Throttle Elevator Aileron Rudder

Before purchasing your first radio, it’s important to consider which radio mode you prefer. Radio mode refers to the configuration of the two control sticks, and there are four modes to choose from: Mode 1, Mode 2, Mode 3, and Mode 4.

There is no right or wrong mode, and it’s just a matter of personal preference. However, if you’re unsure which mode to choose, just go with Mode 2, as it’s the most commonly used mode among pilots. Most radios also ships with mode 2.

Mode 2 has the pitch and roll controls on the right joystick and the throttle and yaw on the left. The right joystick self-centers in both axes, while the left joystick only self-centers in the yaw axis and the throttle stays wherever you leave it to allow for constant throttle.

Most modern radios allow you to switch between all four modes by simply adjusting the hardware and software, so you can try out each mode without needing to buy a new radio.

How to Hold Sticks

holding radio transmitter sticks

The way he’s holding the sticks is called “pinching”


The way you hold your gimbals is an important factor to consider when choosing a radio transmitter. If you prefer pinching the gimbal sticks with two fingers, longer sticks might be more suitable for you. However, if you prefer using only your thumbs to move the gimbals with the rest of your fingers wrap around the back of the radio, you will need shorter sticks.

I have a whole post explaining the different ways of holding the sticks and benefits. There is no right or wrong way, it’s purely personal preference.


The tip of a gimbal stick is called “stick end” and they are usually replaceable. “Pinchers” might prefer a different type of stick end to “thumbers”. Some popular stick end options include ball ends, mushroom ends, and flat ends. Here are the stickends I am currently using and would recommend: Radiomaster Sticky360 Stickends.

Not all gimbal sticks are compatible with all radios, the main difference is in the thread size. Gimbal sticks are normally either M3 or M4 threads, so it’s important to check the compatibility before purchasing stick ends.

radio transmitter switches

Radio transmitters come equipped with an array of switches that you can use to arm your drone, activate flight modes, and perform other functions.

These switches can come in two-position or three-position forms, as well as sliders and rotary knobs. However, as FPV drone pilots, we don’t typically need as many switches as fixed wing flyers do.

Typically, you only need one switch for arming, another switch for the beeper, and a third switch for flight modes. While having more switches can certainly be helpful, they are by no means necessary if you’re primarily flying freestyle and racing.

Radio Transmitter Frequency

Left: 868MHz antenna; Right 2.4GHz antenna.

Radio transmitter frequency is an important factor to consider when selecting a transmitter for your FPV drone. Two of the most commonly used frequencies in the FPV drone community are 2.4GHz and 900MHz.

2.4GHz is the current standard for radio control and is legal for hobbyist use in most countries. Its smaller antenna size makes it a popular choice among pilots.

On the other hand, 900MHz is often used for long-range flying due to its better signal penetration and reliability. While it has narrower bandwidth and requires much larger antennas than 2.4GHz, it is still preferred by some pilots because of its lower frequency. It’s worth noting that the exact operational frequency for 900MHz band differs depending on the region, with most of the world using 915MHz while the EU uses 868MHz.

While there are other less common frequencies used in RC, such as 27MHz, 72MHz, 433MHz, and 1.3GHz, they are either obsolete or used in other specific applications. For FPV drones, it is best to consider 2.4GHz or 900MHz.

External Module Support

Additionally, having an external module bay on the back of the radio can be useful in case you want to upgrade to a different radio system in the future. Instead of buying a whole new radio, you can simply purchase an external module that is compatible with the new system.

It’s important to note that not all radios have an external module bay, so if you think you may need one in the future, be sure to look for a radio that has this feature.

There are two sizes of external module bay: JR module and Lite module (also known as nano or micro size). Take note of this if you are buying an external radio module.

This is JR module bay:

This is Lite module bay:

Betafpv Cetus X Fpv Kit Radio Transmitter Lite 3 External Module

Radio Receivers

The receiver is responsible for receiving the user’s commands from the transmitter and passing that data to the flight controller. However, you can only use receivers that are compatible with the RF link you use, as they need to use the same protocol as the transmitter. Here is an overview of all the TX protocols and RX protocols.

A protocol is like the language spoken between the transmitter and receiver. When you buy a radio transmitter, you are also committing yourself to specific receivers and ecosystem, which has an impact on your budget and feature options. Some brands may have more expensive receivers, while others may have better options for lightweight receivers for smaller drones. Additionally, some brands may not offer certain features like telemetry.

It’s important to remember that you’ll need to purchase a receiver for every quad you build, so the cost can add up quickly if you have multiple drones in your fleet. Take the time to consider which receiver brand and protocol will work best for you and your specific needs.

Binding TX and RX

Binding is the process of establishing communication between a radio transmitter and receiver, which only needs to be done once unless there’s a firmware update or the bind is lost for some reason.

The process of binding is typically straightforward, but the steps can vary depending on the brand.

Keep in mind that while you can bind multiple receivers to the same transmitter, you can only bind one receiver to a single transmitter at one time.

Receiver Compatibility

When you purchase a radio controller, you’re not just buying a single device – you’re investing in a system that you’ll continue to build on in the future. It’s crucial that each receiver you purchase is compatible with your radio, and you’ll need a new receiver for every drone you own.

As mentioned earlier, both radio transmitter and receiver must use the same protocol. To avoid surprises, you can pick your receivers from my receiver round-up based on the RC link you are using:


Not all radio control links are created equal when it comes to range. Three main factors that affects the range of a radio:

  • Maximum output power
  • Frequency
  • Antenna Quality and Gain

Even if two different links have the same frequency and output power, their maximum range can differ greatly due to factors like the technology used and the quality of the hardware.

As a general rule, lower frequency systems tend to be better at long range. However, newer systems like 2.4GHz ExpressLRS with LoRa modulation have been known to perform exceptionally well at long range as well despite their higher frequency. It’s worth noting that line of sight is always ideal for achieving the best possible signal, as obstacles between your transmitter and receiver can significantly reduce range.

In addition, receiver sensitivity and diversity can also impact range. Some receivers come equipped with two antennas for diversity, which can help to mitigate any signal loss due to obstructions or interference. Antenna placement can also make a big difference, as positioning your antennas at a 90-degree angle from one another can improve signal reception.

As an example, older Frsky 2.4GHz radio systems like ACCST V1 and V2 typically provide a range of around 1km-1.5km. However, the latest ExpressLRS 2.4GHz system, despite only using 100mW of power, can provide tens of kilometers of range thanks to its advanced technology and high-quality hardware. For those who are specifically looking for a long-range option, popular systems like TBS Crossfire are also available.

Battery Life

Most radios come with swappable batteries, supporting both LiPo and Li-ion options, and can be conveniently recharged using the USB-C port on the radio. This flexibility ensures you’re less likely to run out of battery in the field, which could cut your flying sessions short. However, some radios feature built-in LiPo batteries that are not designed to be replaced, typically providing enough battery life for a few hours of flying. It’s essential to consider whether this duration is sufficient for your needs.

There are ways to extend battery life, such as reducing the output power level (if the option is available) and adjusting the screen backlight settings by either lowering the brightness or turning it off completely.

Channel Count

Channels in Betaflight Receiver tab

Radio manufacturers advertise the number of channels their radios can support, which refers to the maximum number of individual controls and switches that can be used. Each control or switch on the radio requires a separate channel to transmit data to the receiver.

Channel count is another consideration when choosing a radio, but it’s not as important as it used to be. In the early days of RC, adding new channels was a difficult and costly process. But today, with digital radios and advanced technology, adding channels is much easier. The number of channels you can use is actually limited by the radio link and how many switches are on the radio.

The two gimbals on a radio take up four channels because they have four inputs: throttle, yaw, pitch, and roll. Additional channels, called “AUX channels,” are assigned to switches on the radio for arming the drone and activating other features.

For FPV drone flying, you typically only need 5 channels as a minimum, with four channels for controlling the movement of the drone and an extra channel to arm the drone. You probably also need one or two more for selecting flight mode and activating beeper. So, having a high channel count doesn’t necessarily mean better performance.

Most popular radio links, like Crossfire and ExpressLRS, can support up to 12 channels, and most radios have around 4 to 8 switches, which is more than enough for flying an FPV drone. When following my recommended radio options, channel count is not something to worry about.

Telemetry Support

Telemetry is one of the most important features that you can have in your radio system. It allows you to receive crucial information about your drone in real-time, such as signal strength, battery voltage, current draw, and more. This information can be incredibly valuable when flying, as it helps you to make informed decisions and avoid potential problems.

Most modern radio links support telemetry out of the box, including popular options like ExpressLRS and Crossfire. With telemetry, you can display data directly on your radio screen or receive audio warnings when certain thresholds are reached.

FPV Simulator Support

If you’re new to FPV flying, training in FPV simulators can be a great way to build up muscle memory and practice flying without risking damage to your expensive components. And the good news is, many modern radios with EdgeTX or OpenTX have the ability to connect to FPV simulators via USB and show up as a joystick controller.

So if you’re looking to improve your flying skills, be sure to check if the radio you’re considering supports FPV simulator. It could make all the difference in your training and progress as an FPV pilot.

Trainer Port

Radiomaster Wt01 Wireless Trainer Module Radios

A trainer port is a connector on your radio that allows you to connect two radios together, allowing them to control the same drone. It’s a useful tool for training, allowing an experienced pilot to fly a drone to a safe height and location, then transfer control to a student who can then practice flying without the risk of crashing (and allows the trainer to take over when needed). Radios with built-in trainer ports are highly recommended for this type of training.

Trainer ports typically exists in 4-pin 3.5mm audio jack.

Using a trainer port to train with friends and family can be a fun and rewarding experience, and it’s a great way to share your love of flying with others.

In general, radios of the same brand and model should work together without issue, but it’s important to double check to avoid any headaches down the line.

Radiomaster makes a wireless trainer dongle:

Flying with other people

Unlike your video system, you don’t need to worry about managing the radio frequency of your radio when flying with others. This is because the radio automatically manages the frequency for you. After you’ve bound your radio receiver with the transmitter, the transmitter will only communicate with that specific receiver. This means that other pilots won’t be able to interfere with your signal. Additionally, the radio signal will hop across different frequencies within the 2.4 GHz band to ensure a strong and uninterrupted connection between the transmitter and receiver. This makes flying with a radio transmitter a stress-free experience!

Good call. I just updated it .

Krotow 14th December 2023 - 11:26 am

Still hope to see EdgeTX for TBS Tango 2 radio. EdgeTX promised to care about Tango 2 and Mambo too :) TBS didn’t release the Companion for these two radios so far and without it model configuring is very inconvenient.

As I see, FrSky is kinda dead already. At least in FPV hobby.

Ivan 20th November 2023 - 8:36 pm

Hi Oscar,

I’m planning on starting a research project with students that will build light aircraft. The ultimate goal is to make the lightest and most efficient glider with radio control. The glider should also be able to send back information from flight sensors but also video and other data to be collected during the flight. I would like to get a radio controller that would be compatible with multiple recerivers, in particular ultra small and light receivers. Can you recommend the best transmitter for this purpose? Potentially we can get a very high end transmitter with all the bells and whistles plus a couple of small transmitters that could be used for training. Also, if you can recommend receivers and flight controllers with the lowest weight available that would be great. Thank you very much!

mohamed abidkadir 6th July 2023 - 3:08 am

hey oscar, ive got an at9s radiolink controller and ive been having trouble finding good simulator cables. the ones in the past havent lasted very long or began causing issues with my gameplay. do you have any suggestions

Harel 16th June 2023 - 4:54 pm

Hi Oscar, what is your opinion about the Jumper T-pro v2? it’s not really reviewed anywhere online but it seems pretty appealing to me with 2X18650s and the 1W of ELRS output power, the only other radio with both of those capabilities is the Radiomaster Boxer which is about 2 times the cost.
would you get the Jumper or maybe something like a Eadiomaster tx12 MKII(about the same price but only goes up to 250mw)

Oscar 16th June 2023 - 6:44 pm

I wasn’t a big fan of the gimbal when I was testing the V1 T-Pro, wish it was a bit more recessed into the body to allow for a larger stick travel and more pinching-friendly.
I have to admit there’s currently not a game-pad style radio that ticks all the boxes for me yet, all of them have some flaws in some areas, that’s why I am mostly using the Boxer despite it’s larger.

Harel 19th June 2023 - 4:39 pm

Thanks for the response oscar!
I ended up buying the T-pro as I decided output power and compactness to be the most important(i’ll be mainly flying whoops in concrete walls and 3.5-4 inch long range quads),
hopefully I wont have issues with the Jumper

Tom 25th March 2023 - 2:35 am

I am new to FPV and have taken a few weeks to learn and understand what I need to get the best FPV experience.

I like the advice Oscar has provided here; get a controller and fly a simulator first, to save money on crashes and broken hardware.
I decided that my first kit was goin to be a CineLog35 with TBS Tango II crossfire control and 780p visuals via Caddx Nebula pro and DJI Goggles 2. This should give me very good distance control, signal penetration and very good in flight visuals.
I heeded the wise advice here and order my controller first so that I could practice in a simulator before making my first FPV flight.
Well here I am, controller in hand and I’m already dismayed!
I purchased and installed Liftoff as a means to learn and practice, but this controller can’t even make it through the calibration phase in the simulator software. The pitch control has so much jitter that it cannot maintain center and fails the calibration cycle.

I’m an experienced RC fixed wing pilot and have made several flights on my Mavic 3 Pro.
I could probably fly an FPV without practicing in a simulator first, but this defective equipment would have certainly cost me a bundle of money.

So let me add, to what Oscar has offered above: flying in a simulator first is a decent means to test your controller prior to making your first flight.

Let me also add a -1 to my faith in TBS to produce a reliable product.

Oscar – i own a FrSky Taranis Lite radio. How do I connect the radio thru USB to my PC – PC is Dell Inspiron 17 5000 series.Thanks – I can be reached at [email protected]. Thanks

Papo 14th February 2023 - 7:47 am

Hi, in my tango 2 v3 i have max piwer to 1W. 250mW was in older wersions.

Oscar 14th February 2023 - 12:24 pm

Thank you for the update!

Ken Jancef 25th January 2023 - 2:20 am

I think you need to change the prince and some of the links for the TX16S MK2… the cheapest it can be had is $199USD. One of your links has a version of it for $549. A little misleading…

Robert Beatty 9th December 2022 - 5:57 am

Very well written And extremely informative. Thank you.

Maxwell Boss 23rd June 2022 - 8:38 am

this post is awesome!

C 16th March 2022 - 5:11 pm

In my opinion the 4n1 version of the zorro is better than the elrs because even though i love ELRS the limit of 250mW output power is a dealbreaker for me. I’d rather get the module seperate so i can do 1W ELRS.

Boball 12th August 2021 - 12:16 pm

Does anyone else think there’s a gap in the market here with all those vr type headsets out there that either have a (Android) screen built in or allow you to mount your lovely hd ish 6″ phone screen in them?
Cheap receiver attached (ROTGUT2 in my case) and, in most cases, an improved FOV.
An option to display just the headset FOV but receive the full 150′ and pan around it with head tracking (again already there on a phone) and flatten the image would be great as currently looking at a fish eye view of 150′ FOV on something much less.
Would also love the option of big button on side that switches to phone camera view (hole maybe required!) in an instant to help landing without having to rip the thing off your head.
Presume there are better receivers out there to take advantage of your phones decent res.
Thoughts are welcome, especially if anyone knows of any projects currently exploring this as I’m sure sure some clever bugger out there can code this!
For the above wish list, I’d happily pay a small fee ;)

Boball 12th August 2021 - 12:59 pm

Soz, wrong place, meant to be in the goggles section, obvs!

Mike miles 20th July 2021 - 5:13 am

There seems to be a situation with frsky with their transition from accst protocol to access protocol. My local hobby shop has has quit using frsky altogether. I’d like to have the soplest transmitter possible. My taranis has switches all,over the place and I can’t get it to bind. I emailed them, they told me to switch to the access protocol and then you have to register the receiver to the radio? Maybe the archer receivers would be the answer? I think TBS is my answer.

Oscar 20th July 2021 - 11:31 am

Yes, the community has been steering away from Frsky radios due to their recent change of protocol in new radios and RX.
You can find out how to bind ACCESS receivers here.

Stephano Mgote 2nd February 2021 - 5:16 pm

Can I use a transmitter and receiver found in toy’s car used by children?

Steve Denton 3rd January 2021 - 4:48 am

Hello Oscar, first off, thank you! I’ve been watching, reading, and learning from you for a LONG time now, I mean YEARS. What you do for the rc community is admiral and well appreciated. This is why I’m asking your opinion on this as I truly trust your opinion and judgment (very few people in that club). I’ve been flying for over 35 years and been into quads since the early beginning. I fly with a Spektrum DX18 which I love and have used since it’s release but… it’s getting harder and harder to get things like telemetry and other features to work properly with the ever growing fpv quads that are coming out. So… what is the best radio ( below $1000 bucks) do you recommend me purchasing and then learning (protocol) so I don’t get left behind with my DSMX Spektrum. I prefer the traditional style ( not game controller style) and I’m a thumber. Love Hall effect, and it has to FEEL like a quality non cheaply made materials tx. You know, like the older Futaba 12 channels and JR 8103’s if you remember those. Thanks again and I’ll be awaiting your response.
Oh, and thank you once again!

Oscar 11th January 2021 - 3:49 pm

Right now? I’d go for the Radiomaster TX16S. The built-in multi-protocol module allows you to use your existing Spektrum stuff, and a lot more like the popular Frsky receivers. The external module bay allows you to use Crossfire which is my daily driver. You can pretty much have any modern feature on this radio. The best part is it’s only $160 with Hall gimbals.
Here’s my review: Review: Radiomaster TX16S Transmitter

Janus van Zyl 3rd December 2020 - 9:05 pm

Hello Ozzie,
Firstly, I want to say thank you for saving me quite a bit of time and money and hard school, by writing this blog, I am no longer what you would call a rookie, or intermediate, I fly expert level, I did post on here but can not find it now, so I don’t know if you ever answered me. But I would REEEEEAAALY like to know your opinion on the Jeti Duplex DS14 Transmitters and basically the overall product as I am told it is just about the top of the line? But is it good for FPV?

Paul G 11th August 2021 - 3:27 pm

I would like to konw that as well, I’m thinking about buying a DS16 for my Heli’s but I would also like to fly my drones with it as well

Jon Scott 19th June 2020 - 1:08 pm

Hi Oscar, regarding the Rx size comparisons . isn’t the Spektrum race module smaller now as it’s trying to keep up with basically everyone else? The wires come out parallel now. see DSMX SRXL2

Nick 19th June 2020 - 5:35 am

You didn’t include the Jumper T12 pro? This looks to be an excellent gimbal radio, opentx, with multi-module, lipo charging, same size as Flysky i6. Cheaper even than the Radiomaster TX16s. I’ve read good reviews of it. It is a smaller form factor than T16 etc, but for some, that is a plus, not a minus. If I were looking for a new Tx right now, it would be high on my list.

Scott Baker 14th June 2020 - 9:05 pm

X-Lite Pro is a receiver compatibility nightmare; probably even worse for me since I’m a beginner. But most reviewers on YouTube seem to have the same complaints.


Hasan Sabri 11th December 2019 - 3:59 am

Hi Oscar,
just a quick recommendation for updating the list of popular radios,
the T6 is outdated and should be swapped for the i6/i6s/i6x.
the 9xr is discontinued, and maybe should be swapped for the 9x, as it now supports afhds 2a.

AJmoto 18th January 2019 - 12:42 pm

Hi, why does nobody ever talks about Taranis X9E? Is it not good?

Mikyle 21st November 2018 - 5:16 pm

Hi Oscar. Do you think a Flysky i6X FS-i6X 2.4GHz 10CH AFHDS 2A RC Transmitter will be a good Tx/Rx bundle for a first time tx? Thanks

Oscar 23rd November 2018 - 4:58 am

If it meets what you need then it’s a good combo :)

Andy Goh 20th January 2019 - 3:17 pm

Flysky FS-i6x is an incredible value for money for beginners. It’s slim, light weight, supports 10 channels and uses only 4 AA batteries… For first timer, this is one of the best transmitter out there at around USD50?

Sebalos 12th October 2018 - 2:47 pm


What minimum voltage shall I set up on my taranis X9D plus, standard batteries Ni-MH AA2000 mAh 7.5V ?
I don’t want to drain and damage the bats cells. I know the rule for LiPo is about 3.5 volt per cell.
What about Ni-MH AA2000 mAh 7.5V?

Oscar 23rd October 2018 - 4:33 pm

6V or even safer at 6.5V :)

Oluebube 6th September 2017 - 2:01 am


please, is there any way I could upgrade my Fs-i6x to get a longer range? (not too experienced in this). If not, which other cheap Tx can I get that can reach a range of 1km or above.


Oscar 10th September 2017 - 8:46 pm

I am using Frsky Taranis and I’ve tested it can go 1Km+ with XSR or X4R-SB receivers.

Amir 6th July 2017 - 3:48 pm

Im looking for a Cheap TX which has lots of Cheap and Tiny RX options for miniquads, FlySky FS – i6 okay?

Oscar 10th July 2017 - 5:58 pm

Yes both Flysky and Frsky have many RX options for mini quads.

Arabinda 10th May 2017 - 3:06 pm

I dont know about electronics much. But i am making a small plane by using 2 12v dc motors. I want to control that plane by transmitter. So now what i hav to for. Please help me.

Tom 26th March 2017 - 4:10 am

Hi , I came accross your site as I was googling for building drones. I am gettign into building a hexcopter / quadcopter. what are the max range of these transmitters in miles? Is there a way i can conrll through my laptop ? what software would I need?

Also, when i build a drone can I make it follow something automatically when making movies etc? and make it return to base when battery is low? how are those programmed?
Can anyone guide me on these?


Vladimir 6th January 2017 - 4:01 am

Nice work! It was very helpful for me, when I decide to buy my quadcopter. I want to buy with F3 flight controller.
But Taranis is much expensive for me. Can I use Radiolink AT9 for example? What do you think about that transmitter?

Wayne 8th February 2017 - 10:12 pm

It’s good go for it

Carlos Atouguia 31st October 2016 - 10:12 am


i am looking for someone or a company that will be able to customise my transmitter. i want to put the throttle on a trigger button and not on the stick.

does any one know of any company anyone that is able to do that?

Zeeshan 21st August 2016 - 12:08 pm

I am new into quadcopter world and your article was a blessing for me. i have built a basic quadcopter that lefts off 30cm from ground….i made an adnroid app for this……moving ahead for more, its getting difficult as i was using arduino with gryo+accelermeter……very frustrated and challenging…..i had decided not to use receiver etc and build from core.
after 4 months trial, i was unable to make a perfect one and the cost on it was increasing day by day… no i decided to use receiver and transmitter….
can u help me answer few questions:
1. these receivers have built in gyro+accelerometer or we use external ones?
2. how do i connect my ESC to it?
3. do we need a flight controller as well?

sorry for such basic questions….but these basic things are needed by my small brain

Weebly Reddit 4th April 2017 - 5:24 am

Your drone’s flight controller should have a gyro/accelerometer built in.

Yes, heck yes.
You need a flight controller/

Amir 6th July 2017 - 3:44 pm

In theory you dont need a FlightController, you can just hook up Servo connectors of the ESCs to a PWM Receiver and viola, you control motors, but you dont have any sort of stabilization

Siamak 6th September 2018 - 11:15 am

I would say that Oscars pages are among the most complete and comprehensive documents about FPV (and drones in general) I have seen. I recommend you have some patience and read these pages from beginning in order to acquire more understanding of drones in particular FPV’s and at the same time get your questions answered. It will take time (hence the patience needed) but believe me it’s worth it.

David Frayne 22nd June 2016 - 5:16 pm

Hi I have a spektrum dx7 tx and RX will this work on the Eachine 250 racer I am well used to setting it up what are your thoughts

Jonathan 17th June 2016 - 10:08 pm

Hi Oscar

Note that in the UK, and many other countries outside the US, 72MHz is illegal. The equivalent here, for aircraft only, is 35MHz.

There’s also 40MHz, but this is only legal for land-based craft.

Oscar 19th June 2016 - 10:47 pm

good point guess i missed to mention that i will add a few words in the tutorial shortly! thank you Jonathan!

justin 17th June 2016 - 11:31 am

Hey oscar i have a turnigy 9x with er9x. i was wondering if you ever setup throttle curves to reduce sensitivity when the sticks are a mid point? maybe you could write an article regarding mixes that you use?

Oscar 19th June 2016 - 10:41 pm

I normally don’t setup curves on the TX, so I can have full resolution throughout the whole stick range… what you are asking is just rate which you can change in FC isnt it?

Robin 14th June 2016 - 8:01 pm

No love for Deviation TX?
Surprised it doesn’t get a mention?

Oscar 19th June 2016 - 10:28 pm

lol sorry not much experience with Deviation TX, neither from my editor Justin and people flying mini quad around me…

Greg 22nd June 2016 - 12:05 am

Deviation is a replacement firmware designed primarily for the Walkera Devo series RC Transmitters. While Deviation is heavily influenced both by the Walkera DEVO8 firmware as well as by the Flysky/Turnigy based ER9X firmware, it has been written completely from scratch to be easily portable and extensible.

The supported transmitters are the DEVO 6/6S/7E/8/8S/10/12/12S/F7/F12E

The Devo 7e is one of the most highly recommended entry level TXs out there. The Deviation firmware is actively maintained and developed, a new major version, 5.0.0, was just released. There’s also an awesome user base and support community at to help out with any mods or issues.

Raihan 2nd March 2016 - 12:29 pm

Riaan Theron 1st February 2016 - 12:13 pm

Hi Oscar,

I got a Syma Drone for free with no remote and manual can i use any 4CH 2.4G remote control for my Quadcopter.Please can you help

Robin 14th June 2016 - 7:56 pm

Have a look into a Walkera Devo transmitter and flashing DeviationTX to it
It’s an open source firmware and has been 100% solid for me and allows me to fly all my models
(from toy quads to 250 fpv quad …and a fleet of helis… from toys to 450 size…and a plane and a buggy.. :D )

Abhinav 14th November 2015 - 7:07 am

Hi Oscar,
I have a 4ch transmitter of 2.4GHz freq and i want to connect it my laptop for which dsc port should be present in the transmitter but there is no dsc port. What can be done? plz help.

Fatemeh Hashemi 22nd October 2015 - 12:33 pm

Hi, Is there any way to control the Quadcopter with mobile phone?

Jonathan 26th September 2015 - 4:02 pm

Hi Oscar,
There are tons of transmitters out there, of which most are pretty useless when it comes to Multicopters or FPV.
There is absolutely no need to get into the high end computer TX with big color screens e.t.c, as all you will ever need to do is have a couple of AUX switches for stuff like flight mode, GPS modes. maybe a camera slider, and a switch for adjustment of maybe PID’s, if your FC supports this. But most transmitters are going to be loaded with features that you wont ever use.
Stick with a nice mid range 6 to 8 channel TX and as long as its capable of channel assignments and channel reversing, that’s all you are ever going to need.

luisen 20th September 2015 - 7:51 am

Hi Oscar

after years of computer-flight-simming i am starting to get interested in the quadcopter “hype”, especially FPV seems like something i could enjoy very much.

i bought and played around with the FPV freerider game to get a feel of quadcopter controls and i am loving it. but i am concerned about one thing:

on a real R/C receiver device, can i have the PITCH/ROLL on the LEFT stick and the THROTTLE/YAW on the RIGHT stick? this is the only configuration i personally can fly properly with the FPV view and it feels completely natural to me. but now i see this completely different to both the 2 modes used in real life quadcopter flying.

so i guess my question, can you easily switch YAW and ROLL on a MODE 2 receiver? or do i need to look out for a special one to buy?


Oscar 21st September 2015 - 3:17 pm

HI Luisen,

I guess you mean you are more used to MODE 1 TX (Transmitter)?
Most TX are available in both MODE 1 and 2, so that’s not a problem.
It won’t affect your RX (receiver).

Kenneth 4th January 2016 - 12:56 am


When you setup the receiver with your quad, you have to manually connect the receiver to the flight controller. You can simply plug them in whatever order or configuration you want. If you want the throttle on the right, you will swap the gimbals out on the transmitter for mode 1, then plug the channels into the flight controller to suit your needs! good luck!


Darrell 3rd October 2016 - 10:01 pm

You need a transmitter that will do mode 3, Hitec Aurora9, Frsky Taranis both can do this.

Aeromodelling 9th September 2015 - 11:31 am

Very glad to read your blog.Thank you for sharing this article.It is great! I will keep your article in my idea. Very happy reading.

Mike 25th August 2015 - 7:58 pm

Hi Oskar!
I have spent a lot of time reading your blog and it gave me a lot of tips. Thanks!
I’m trying to figure out how RC transmitters work.
1. RC transmitters are universal? meaning, a 2.4GHz RC transmitter can work with any 2.4Ghz receiver that I buy? if
not, what characteristic other than the frequency should I check to be sure that they will work?

2. Where can I find more information about the binding proccess between the transmitter and the reciever. What is the init sequence? How is it done? etc.

Thanks a lot!
Mike S.

Oscar 26th August 2015 - 3:41 pm

Hi Mike
1. no… transmitter (TX) usually only work with RX of the same brand… or they should specify which one they are compatible in the product page. Quick google of the TX should also give you some options of what RX can go with it.
2. binding process might be slightly different from TX to TX… i suggest consulting the manual.

Abhitosh 1st August 2015 - 5:05 pm


can i control a quadcopter for laptop without any other transmitter…
what program requaired to controle it

Oscar 6th August 2015 - 12:28 am

It’s best to have a transmitter for safety as it’s easier to control.

Fikri 30th June 2015 - 3:59 pm

Hi, im a newbie at this. Can esc in quads be programmed in a way that only 1 side has throttle and no throttle at all on the other? this would cause the quad to flip i suppose?

With that, is there a way we can program the controller to like trigger a switch when we want the quad to flip? Cause i was thinking of doing a waterproof quad. So initially it flies in the air normally with the 4 channel, and thn i set it to float on water. After that, i was thinking of maybe triggering a switch on the controller so that this time its just gonna flip and nothing else. After it flips, i would trigger the switch back to normal operation. Is that possible?

Do help me out, thank you guys :)

Dario 31st May 2015 - 9:25 am

Hi Oscar,

Im referring to the last part in your article about the Transmitter and its hacking.

For a University project i plan to hack a transmitter and control my quadro with Data I generate in Arduino or Processing. have you come along with a transmitter that can be adjusted to to this?

Although Im not super experienced, i imagine the flow of communication like this: my input -> RC transmitter -> rc reciver -> flight controller -> AC -> Motor.

Can you help me some how?

Best regards

rick 17th May 2015 - 12:14 pm

i have a hobbyking 6ch transmitter….it works complicated. does annyone know how you set the right settings for quadcopter?

Esmyle 2nd May 2015 - 9:52 am

quadcopter need 4ch mode matter what brand.. am i right?

Oscar 1st May 2015 - 4:08 pm

yes, regardless brand, you need 4ch.

Christopher Boyd 20th April 2015 - 12:05 pm

Hello Oscar
I am reading through all your blog/posts that are so informative. Thank you for taking the time to share you hard won knowledge and skills.
I have been dabbling in Quads for a few years and decided that I would be in it for the long haul, so……I bought a taranis X9D (Nov 2013). It is a very nice piece of equipment but very complicated for a novice user. I am now spending many hours to learn many basic things so I can actually use it for the first time. It has the potential to run in four “modes/configs” that allow you to use either, 8,12, 16 or 32 channels. It is enabled for telemetry as well.
I will be connecting it up to the first “serious” copter- a Quanum Nova (aka Cheerson Cx-20), initially using an 8XR FrSky receiver. I think that using different “flight modes” (which I can assign to the various toggle switches) I will be able to use the limited 8 channels for the four motor controls, one for GPS, 2 for the camera gimbal (2 axis only), one for camera shutter. This equals Eight. I am not sure how the telemetry data gets back to the Transmitter. Any one help with that?
If this is of interest to others I will post some more on it as I work my way through the maze.

Oscar 21st April 2015 - 6:12 pm

Can’t agree more Chris! The Taranis is an excellent product.
I will write a guide on how to setup taranis telemetry in a week or two hopefully you can wait! :)

christopher Boyd 22nd April 2015 - 10:50 am

Hello Again.
I just got back to your blog through another circuitous route. I was searching for “understanding flight modes” and “understanding switches” so that I can set up the controller side of my quad on the taranis. I do not understand these adequately yet. Any advice where to find a good tutorial that will give me the fundamentals of what happens when switching flight modes, how switches are used for this. I am not clear if I use a witch will it reallocate one of the radio channels to another function allowing me to effectively increase my number of channels (…..but I still only have 8 receiver channels that are hard wired to the assets on the aircraft…?)
Your somewhat confused pupil!

Oscar 22nd April 2015 - 12:57 pm

Please join our FB group, lots of people can offer advice there, link on top left of the website.

King Kaiju 11th March 2015 - 8:51 pm

Hey I just ordered a Syma X5C-1 (4-channel with a 4 channel remote), is there anyway I can upgrade the the transmitter/receiver? I also want to see if I can upgrade the battery life and flight distance. What do you think?

Oscar 15th March 2015 - 6:32 pm

I don’t think you can upgrade the TX/RX on a RTF quad.

Robin 14th June 2016 - 7:51 pm

Yep, certainly the TX benefits from a better one – if you google for Deviationtx if will give the lowdown
I’m surprised Deviation doesn’t get more of a mention on here TBH, electronics tinkering galore :D

gerrypw 17th June 2016 - 3:56 pm

I am sure you have moved on to other quads by now but the x5c is a good way to cut your teeth in this field of play. You can mode your TX for longer ranger which you might have discovered already. Have fun.

daristiz 14th February 2015 - 10:20 pm

Hi oscar. I bought a 9xr radio But I’m confused about what transmitter and receiver should I Buy.
Could you Give me an advise about this and Maybe give me some link? Thanks in advance.

Greetings from South América

Oscar 16th February 2015 - 5:05 pm

sorry wish I could help, but I don’t have a 9XR so not sure what receivers are compatible. Try googling it.

Hizzy 13th March 2015 - 11:52 am

This is the recommended module set up for 9XR.

firdaus 2nd February 2015 - 7:47 am

Hi Oscar,
I have Esky Belt CP V2 Heli which is 6Channel transmitter and receiver. Can i use it for Quadcopter? I plan to buy ARF kit Quad.


Oscar 2nd February 2015 - 9:16 am

Yes I think it should work :)

Daniel C. 23rd January 2015 - 3:36 pm

Oscar please help me I have a ton of questions to many to ask just now. Text me please at 915-400-6422 ur blog helped so much I’m sure you can help even more.

Pakal 19th January 2015 - 12:45 pm

“They are more expensive radios transmitter, but they do have nicer gimbals, maybe better resolution.”
What is the function of a gimbal in a transmitter? And how many gimbals there are in a transmitter and where is it located inside the transmitter?
Thanks for your reply.

Oscar 19th January 2015 - 1:09 pm

Hi, are you thinking of camera gimbal? it’s not what I meant there. Transmitter gimbal looks like this

Pakal 19th January 2015 - 10:10 pm

I was actually thinking of the transmitter gimbals. And just when I hit the “post” button, I realized that those mysterious internal gimbals have actually been right in front of my eyes the whole time!
Thanks for replying anyhow.

alu 13th January 2015 - 9:58 pm

Hi Oscar,
Nice tut,

How do you think about the idea that we use other (separated) telemetry using 433mGhz rf modul for other control like switch flying modes, gimbal control or camera ctrl?


Matthis 23rd December 2014 - 11:03 am

Hi, I chose the JR PROPO XG8 whith RG831B receiver and I’m building my own drone quadcopter . I would like to use the flight controller naze 32 but I saw on the net that it does not work with the DMSS modulation, is it true? is there any possibility to solve this problem? if there is no way, I will buy an other flight controller but It’s difficult to find informations about this so do you know any flight controller that i can use with my RC ?

I am sorry for my english I think it is not really correct …

have a nice day,

Oscar 24th December 2014 - 9:39 am

sorry i am not sure, i have never come across the JR PROPO XG8.

shushant 19th September 2014 - 7:18 pm

Hello sir,
I am a beginner. ….u also can’t say me a beginner because I am very keen about quadcopters I just love them. I am just 14 I saw a video on YouTube on how to make a quadcopter. I am confused about the RC transmitter.

1) on the video it showed that u need a transmitter and reciever with 4ch……I live in india and there I found all other parts but I didn’t found the RC controller.pls help me with some indian sites selling 4ch transmitter
2) I am getting a 6ch transmitter at a low cost so should I buy it as I am worried tht I won’t have a 4 ch reciever as shown in the video and it won’t work.

Thank you

Oscar 19th September 2014 - 8:28 pm

Hi Shushant,

sorry i don’t know any India sites that sells RC stuff, but I do know a popular International site that sells them.
Check out this page:


Walid 17th August 2014 - 12:52 pm

I would like to know which RC transceiver i can use to reach more than 3 kms

Ashade 9th June 2014 - 8:17 pm

Would you recommend the newer 9xr instead of the 9x or would you directly go for the Taranis.

Thank you in advance

Nitish 2nd June 2014 - 5:58 am

I am a beginer.Is FR SKY CT6-B 6ch is fine for a quadcopter.In future I want to upgrade my copter. For quadcopter with GPS navigation how many channels(minimum) required.

Oscar 2nd June 2014 - 10:39 am

Get 8 channel, you won’t regret it!
4 for basic control, at least 2 for switch modes, 1 or 2 for gimbal control, or/and FPV cameras switch (recording camera & FPV camera)

i just had a basic doubt,I have a transreciever with 3 channels,but your blog seems to suggest that we have a minimum of 4 channels. Can I not send the data on same channel by multiplexing,which reduces the number of channel usage.Please enlighten me on this matter.

no it won’t work, you need 4 channel at least for a quadcopter.

I’ve been away from RC for some years and thinking about getting back to flying.

Can my many years old JR X3810 transmitter fly quadrotor? I’ve already upgraded my radio with a 2.4Ghz module (it’s frsky mudule). Which mode do I have to choose in the radio, heli or plane?

Thank you so much.

as long as your transmitter has more than 4 channel then it should be fine.
use heli mode, that’s what i am using on my Turnigy 9X.

Keep on working, great job!

Hi there,
as far as I know the Turnigy 9X can’t handle the fail safe: is that correct?
It would be a very best buy but I really need the fail safe feature for my esa and, even more, for my “flying cameras”: how to solve?
Any advice?
Best regards, Marco

Oscar 27th February 2014 - 3:09 pm

Hi, yes, that’s correct, the 9X doesn’t come with fail safe feature.
to have that feature, you will need to upgrade to a better TX module, e.g. FrSky TX module.

find out more about how to upgrade TX on 9X.

One option is to use a flight controller with two way telemetry. That way you can trigger a RTL event if the RC transmitter or receiver fails.

I purchased a Turnigy 9XR from HobbyKing for under $60 US without a transmitter module. It has open source firmware available and can be configured from an application on your PC. You can buy a transmitter/receiver module on 2.4GHz, 430MHz and several others to suit your frequency and distance needs.

For the hacker (like those of us visiting Oscar at his Internet home here), OrangeRX makes a TX/RX module based on the Arduino that can be customized.

The Turnigy 9XR, OrangeRX TX/RX on 430MHz, a FlySky TX/RX on 2.4GHz and programming hardware together cost less than the JR XG8 we bought my wife ($450 US at a local hobby store). The JR feels like a higher quality transmitter, but I like to tinker. :-)

Oscar – Thanks for all your efforts with this site.

Yes, very good point.
One thing everyone should be aware of is, what frequency bands and signal power are allowed for personal use, before buying the equipment.
Although it’s unlikely anyone would find out or even care, but it’s important we fly safely and do not affect other people.
Some times i envy people living in the states, many frequencies are open to public.

Should the RC transmitters , motors and ESC’s be of the same company.

Hi there, I need to purchase a transmitter/receiver but I just not sure where can i get it for a better or cheaper price. My goal is to be able to fly my x quadcopter for at least 10 to 12 minutes and we are also looking for one extra channel for the landing purpose. Can you suggest me a better place to purchase it. Thank you for your time. Best regards.

Oscar 29th October 2013 - 11:10 pm


try, they sell RC stuff at really low price. Another place to look for cheap transmitter would be ebay.
remember it doesn’t has to be expensive, for quadcopter, 4 to 6 channels would be enough. But if you are thinking about long term investment, Turnigy 9X is a good one (9 channels, and lots of potential for modification).

Yep , Hobby King , right one : serious , listen to the customers , fast mailing , simply one of my favourite :)
( HobbyGaGa for the price too and banggood is multipurpose so I can joint Arduino orders with RC one )

I like :
“They are more expensive radios transmitter, but they do have nicer gimbals, maybe better resolution.”
If you search in Futaba , or something equal, yes it’s expensive and would like to try , on day , If the difference justify the price ~|:
=> Thought last month …

Today I can feel the difference between the HK-T6A-M1 , and Walkera DEVO12 , and the ration Price / Quality is sensable ( syntax ?? ) … ( HK-T6A-M1 :20.33€ / Walkera DEVO12E :148.99€ ), ok we have 6 channels more , but the stick linearity … The sweetness of the stick . All the type of “pilot” Mode : 1,2,3,4
the stickers and all serigraphy are for mode 2 , I fly in mode 3 :) Totaly reversed :) as My brain :)
If you plan to test at the beginning the HK is quiet what’s we must have … when virus propagates … it’s another story :) ( where are my pills ?? )

thanks Garfield, yes most of the times we don’t have the chance to try every products, and many reviews on the internet isn’t always true. That’s why it’s good to meet people on the field, and try their gear :D
