How To Choose RC Transmitter For Quadcopter

Taranis_06--radio-transmitter

Before building your quadcopter, Radio Transmitter should be one of the first few items you need to look at. It’s a common question for RC beginners, how to choose a suitable RC transmitter.

In this article we will discuss the basics of a transmitter (RC Controller) and what you should look for when buying one: price, the number of channels, modes, frequency and other features.

Article was first created in October 2013, updated in June 2016.

Table of Content

Channels

The number of channels determines how many individual action on the aircraft can be controlled.

For example, channel 1 for throttle, channel 2 for yaw (rotating right and left), channel 3 for pitch (pitch or lean forward and backward), channel 4 for roll (roll or leaning left and right).

As you can see, four channels is the minimum amount of channels needed to control a quadcopter (pitch, roll, throttle, yaw).

RC-transmitter-channels

If there are additional channels on a transmitter, they are normally used as AUX channels for switches and pots (potentiometer or knob). You can use them to change flight modes or trigger certain function/features on the multirotor.

In general it is recommended for transmitters to have at least 5 or 6 channels for a quadcopter. The extra 1 or 2 channels can be used to arm the quad and/or switch between different flight modes.

5-channel-transmitter-diagram

Transmitters with more channels (6+) are generally speaking more expensive, tend to have better build quality and are more functional than a basic 4 or 5 channel RC transmitter.

The stick control on a radios TX is called a gimbal. (don’t get confused with camera gimbal :D )

radio controller gimbal - transmitter RC

Modes

There are 4 different Modes – mode 1, mode 2, mode 3 and mode 4. These are basically the different control configuration.

Mode one configuration has the elevator control on the left joystick and the throttle on the right one.

Mode two is the most common for quadcopter because the stick represents the movement of your quadcopter. It has the elevator control on the right joystick and the motor throttle on the left one. The right joystick self centres in the both axis, whereas the left joystick only self centres in yaw axis (left/right direction) and clicks or slides in the throttle (up/down) axis in order to allow constant throttle.

stickmodes

Mode three – same as Mode one except Aileron and Rudder are swapped.

Mode four – same as Mode two except Aileron and Rudder are swapped.

Because the identical gimbals configuration, in some TX, Mode 1 and Mode 3 are exchangeable, as well as Mode 2 and Mode 4, by swapping Aileron (roll) and Rudder (yaw) channels in user settings.

Frequency Technology

Common frequencies used in RC radio are 2.4GHz, 27MHz, 72MHz, 433MHz, 900MHz and 1.3GHz. Don’t worry about all these numbers, majority of us use 2.4GHz these days, unless you have specific needs for a different frequency. Just in case you are interested here is some brief and interesting technical background.

For those of you who have been around the RC scene for some time, you will remember 27MHz and 72MHz with the frequency/channel crystals (crystals were tuned to specific frequency channels to transmit the signal to the receiver which had its own same channel crystal essentially binding them together). This technology has been around for decades, they allow longer range and better signal penetration. However you could interfere with others using the same frequency (even different brands). Another problem was the large size of the antennas as they could reach a few feet in length. Crystals used for channel selection were also inconvenient as they broke easily and could constantly and annoyingly change when flying/driving with others.

Nowadays the 2.4GHz system is a newer technology, and it’s currently the most common frequency for small RC ground and air vehicles. It becomes the RC standard after new protocols were created that introduced frequency hopping technology which allowed the user to not have to worry about picking up frequencies or channels from other pilots. Antenna is smaller and easier to carry, but usually with shorter range than the 27/72Mhz.

You may have also heard of others using 1.3ghz, 900mhz or 433MHz equipment, these are more commonly used for long range or on larger crafts.

All the transmitter manufacturers switched to the new channel hopping protocols which made RC very easy to maintain and use. The software running is constantly scanning for the best frequency to use and if it detects any interference, automatically switches to another available channel. It is doing this many times per second so you never experience glitches or radio interference which was a big problem in the RC industry for many years. Another good thing about channel hopping is that you can fly with many other people at the same time without getting interference.

RC Transmitter and Receiver Paring

A transmitter usually comes with a receiver. Be aware that some brands of transmitters are only compatible with (or limited to) their own brand or model of receivers. That means when the receiver is broken you would normally have to get the same one.

This is not always the case though, as there are now lots of options that can be paired with other receivers that are using the same protocol (for example spektrum). Make sure you check and ask the shop for advice before purchasing.

Binding the transmitter to the receiver is very simple, and is only required to do so at the first time you setup a new receiver with the transmitter. Most decent TX will allow you to bind multiple receivers to the TX, and save each one with different settings (aka models, or profiles). Check the instructions for binding procedures that comes with the receivers.

What RC transmitter should I get?

Budget and Channels

The price range is huge, from as cheap as $20 to well over $1000. The cheaper the radio, the lower quality it would be (casing, gimbals, switches etc), and the fewer channels you are going to get.

If you have a tight budget and not committed to the hobby, it would make sense to get a cheap 5 or 6 channel one, just to get a taste of flying, and later on upgrade to a better transmitter when you are more experience and know what to look for. It’s a good idea to have a backup transmitters anyway.

However if you are serious about quadcopters and someday want to run GPS navigation, gimbal control etc, it’s better to get 8 channels or more.

Hardware and Features

There’s a lot to consider when it comes to choosing a good transmitter, such as the display screen (if there is backlight), how the sticks feel, multiple model memories and Training features (Buddy mode), and so on. Some may also like the expo and curve functions which allow you to change how the sticks react to your input by softening there feel at points you setup. (although this can also be done in the flight controller firmware, which is actually preferred by many pilots so you don’t change the sticks resolution and inputs on the radio)

Some RC transmitters support programming and firmware flashing to enhance user experience. You can personalize them with music and voice recordings or whatever you’d like. Do your research before spending good money on it.

Why invest in a good transmitter

An RC transmitter is a long term investment.

With programs available such as cleanflight, we can setup the additional channels to tune the quads in flight. This makes having a transmitter with additional AUX channels a big benefit. Having the ability to save multiple models is an added benefit of having a better radio as this allows one transmitter to be used for multiple craft.

Another benefit of a high end transmitter is the possibility of direction connection to computer via USB, and use it for flight simulators. You can get used to the feel of the sticks/controls, this not only benefits you by speeding up the learning curve, but also helps improve your skills even when you become an advanced pilot. Simulators also allow you to use your own transmitter so that you can practise with it and get to know its functions very well before you even use it to fly your actual quad. Some  cheap transmitters can also do this but requires a lot more tinkering and accessories.

Recommedation on 8+ Channels RC Controller

For a low budget build, Turnigy 9X is relatively affordable, and has a lot of room for DIY/Upgrade modifications! See my review about this Transmitter.

The 9XR or 9XR-Pro is a step up from the 9X. It has similar functionality to other higher end transmitters but comes in the most basic forms to keep costs super low. It is programmable so you can modify it and flash various types of transmitter firmwares on it, has the ability to load custom sounds, music to program to the switches and different functions. Since it also uses external modules you can use it with a couple of different protocols such as Frsky, Orange (dsmx/dsm2). There are many mods that can be done and there is a whole open source community surrounding it which gives its users endless options.

If you have enough budget, check out the Frsky Taranis. It is one of the best reasonably priced transmitters and has swept the FPV industry to become the most popular transmitter.

Other options for higher end units are the Futaba T10/T18, Spektrum DX9/DX18, JR-XG11/XG14 among many others. See this comparison review of the DX6 and Taranis by Artur Banach.

Something else to consider if you plan to stick with the hobby and maybe are looking for something more functional and advanced is tray style radio/transmitters. Tray style radios were traditionally used by plane pilots who needed layouts that gave them easy access to multiple switches and pots. Later the big industry UAV pilots turned to them as they gave them the most function and ergonomics with there needs for accessing various controls at once. They used to be very large, bulky and required shoulder straps to comfortably hold them. Since then, they have become nicer looking and smaller in form which has made them more accepted and popular.

An example of a really nice new tray transmitter that has been very much anticipated is the Frsky Horus. Not only is it functional and ergonomically superb, it looks really cool! Release date will be announced shortly as the last stages of beta testing are currently taking place now.

There are several tray transmitters out right now but tend be on the more expensive side. Can’t stress this enough, do your research before you buy something of this caliber as it will become a very big investment (depending how deep your pockets are).

    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.

        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 deviationtx.com to help out with any mods or issues.

    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.

    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?

    thanks!

      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).

      Reply
    2. Kenneth

      Oscar,

      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!

    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!

      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.

    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 :)

    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.

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…?)

        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.

      2. Oscar

        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.

      Hiya,

      try Hobbyking.com, 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).

        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
        BUT
        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

      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.
