What is a Quadcopter Flight Controller
The flight controller (a.k.a FC) is the brain of the aircraft. It’s a circuit board with a range of sensors that detect movement of the drone, as well as user commands. Using this data, it then controls the speed of the motors to make the craft move as instructed.
Nearly all flight controllers have basic sensors such as Gyro (Gyroscopes) and Acc (Accelerometer). Some FC include more advanced sensors such as Barometer (barometric pressure sensors) and magnetometer (compass).
The FC is also a hub for other peripherals, such as GPS, LED, Sonar sensor etc.
FPV drone flight controllers are rapidly evolving: becoming smaller, with more features integrated, and using better processors and hardware.
Flight controller sizes, MCU and features
FC Connection
Here is an example wiring diagram how components in a drone are connected to a flight controller.
Flight Controller Firmware
In addition to hardware options, there is also different firmware you can choose to run on your FC, which offer different features and specializations for various applications. For example iNav is designed with GPS utilization in mind, whereas KISS is more focused on racing and ease of use.
Here is a list of popular FC firmware available for mini quad. If you have no clue which one to choose, my recommendation would be Betaflight.
Flight Controller Firmware
Betaflight is open-source, developed and maintained by the community. It has the biggest user base, so you will be more likely to get help when you run into problems. It also has the widest range of flight controllers.
Other popular firmware for FPV drones are FlightOne and KISS. They are both closed source, and the hardware and firmware are controlled by private companies so you are limited to their own flight controllers.
Once you have picked your FC firmware, you can look for a compatible flight controller board.
Interface and Configuration
Modern FC firmware can be configured via a computer, smartphone, or even from your radio controller. Each firmware offers a different user interface (UI) with various parameters you can change. Some UI looks similar, but plugging the same settings into a different FW can give very different characteristics, so there is a learning curve when getting into a new firmware.
“Tuning” is the term we use in the multirotor hobby when changing parameters such as PID, RC rates or other settings to achieve the flight characteristics we want.
Processor
The processors in FC are also known as micro controller units (MCU), they are used to store the firmware codes and handling all the complex calculations.
Currently, there are 5 main types of MCU used for FC’s: F1, F3, F4, F7 and H7. The main differences being the calculation speed and memory size:
| F1 | F3 | F4 | F7 | H7 | |
| Speed | 72MHz | 72MHz | 168MHz | 216MHz | 480MHz |
| Memory | 128KB | 256KB | 1MB | 1MB | 128KB |
This article explains the differences between F1, F3, F4 and F7 MCU in more detail.
We recommend getting either an F4 or F7 flight controller, because F1 and F3 are no longer supported in the latest versions of Betaflight due to the lack of storage for the expanding firmware.
FC Processors: from left to right: STM32 F1, F3, F4
What is UART in Flight Controller?
UART stands for Universal Asynchronous Receiver/Transmitter.
UART is the hardware serial interface that allows you to connect external devices to the flight controller. For example, serial radio receivers, Telemetry, Race Transponder, VTX control etc.
Each UART has two pins, TX for transmitting data and RX for receiving. Remember the TX on your peripheral connects to the RX on the FC, and vice versa.
For example here are the UART3 (R3 and T3 pins) and UART6 (R6 and T6 pins) on a flight controller. You can assign these UART a task in the ports tab of Betaflight configurator.
How Many UART’s on an FC
You might not need many UART’s, but having more is always handy.
The number of UART’s available largely depends on design of the board, and the processor used. For example, F1 FC normally only has 2 UART’s, while F3 and F4 can have between 3 to 5 and F7 can have 6 to 7.
| F1 | F3 | F4 | F7 | |
| No. of UART | 2 | 3-5 | 3-6 | 6-7 |
UART and Inverted Signal
F3 and F7 can handle inverted signals natively, while F1 and F4 cannot.
Frsky SBUS and SmartPort signals are inverted at the output, the good news is F3 and F7 flight controllers can read these signals just fine. Because they are newer generation processors with integrated inverters.
However, older processors such as F1 and F4, require an external inverter to “translate” the signal before feeding it to the UART. For users convenience, almost all F4 flight controllers have dedicated pads for SBUS you can connect the RX directly to. Otherwise, you can use a workaround, such as using soft serial for SmartPort, or getting uninverted signal from the RX.
If you are running out of UART ports, you can use the Betaflight feature SoftSerial to “create” up to two extra UART. SoftSerial is a way of emulating a UART port using software, but the emulated UART has lower baud rate (update rate). This makes it unsuitable for timing critical tasks such as for the RX connection. Note that SoftSerial also increases CPU load.
Gyro Sensor – The IMU
The job of an IMU sensor is to measure the quadcopter’s movement and orientation. An IMU sensor contains both an accelerometer (ACC) and a gyroscope (Gyro).
The most used flight modes in Betaflight are probably Acro mode (aka manual mode) and Angle mode (aka self-level mode). Acro mode uses only the Gyro, while Angle mode uses both the ACC and Gyro.
Since most FPV drone pilots only fly in Acro Mode, the accelerometer is often turned off to free up processing power. That’s why we normally refer to the IMU simply as the gyro.
The following list contains the most common IMU chips for FC.
The Types of IMU
| IMU | Possible Communication Protocol (BUS) | Max. Effective Gyro Sampling Frequency |
| MPU6000 | SPI, i2c | 8K |
| MPU6050 | i2c | 4K |
| MPU6500 | SPI, i2c | 32K |
| MPU9150* | i2c | 4K |
| MPU9250* | SPI, i2c | 32K |
| ICM20602 | SPI, i2c | 32K |
| ICM20608 | SPI, i2c | 32K |
| ICM20689 | SPI, i2c | 32K |
* MPU9150 is effectively MPU6050 with an integrated AK8975 magnetometer, while MPU9250 is MPU6500 with the same magnetometer
You can find the IMU model number printed on the chip, for example this is the popular Invensense MPU-6000.
Gyro and Accelerometer on a flight controller
The Choice of Gyro: Sampling Rate vs. Noise
There are two main properties of an IMU to consider in a flight controller: max sampling rate, and how susceptible to noise (both electrical and mechanical).
Currently the most widely used IMU is MPU6000 as it supports up to 8KHz sampling rate, and is proven to be one of the most robust IMU against noise. The general consensus is to avoid MPU6500 and MPU9250 despite their higher sampling speed.
There is also a performance difference between ICM series gyro’s. The ICM20689 is one of the worst gyro for flight controllers, susceptible to noise and with a high failure rate. If you had to pick an ICM gyro, go with 20602 instead.
There are some FC with the Gyro “soft mounted” on foam in order to reduce calculation errors from vibrations being transferred into the system from the motors.
Soft mounted Gyro – Kakute F4
Update (Oct 2019): Since Betaflight 4.1, 32KHz mode had been removed, so even if you are using an ICM gyro with Betaflight, you can only run up to 8KHz looptime.
One of the reasons BetaFlight removed 32KHz support may be due to faster a gyro being a double-edged sword. A smooth craft with clean signal and power, can expect the ICM series at 32KHz to perform better than the MPU6000 at 8KHz. However introduce electrical noise from ESC & motors and/or physical vibrations, and the degradation in performance of the ICM is far worse than the MPU6000.
Here are some tips on soft-mounting and filtering capacitors to reduce noise
Gyro BUS – i2c and SPI
SPI and i2c are the types of “BUS”, or communication protocol between the IMU sensor and processor. The type of BUS has a significant impact on the effective sampling rate and the maximum flight controller looptime.
The preferred BUS is SPI, which allows you to run Gyro at a much higher refresh rate than I2C which has a limit of 4KHz. Almost all flight controllers today uses SPI.
Layout
FC layout is where the pins / solder pads are located on the board, and how easy it is to connect the components.
Many people only care about the capability of a flight controller, and can overlook the importance of the layout.
A good example would be the CLRacing F7 and the Kakute F7. Both are excellent flight controllers that I personally recommend, but purely based on the layout, the CLRacing F7 is clearly superior, as all the pads are all located on the edges, and grouped by the function. The pads on the Kakute are all crammed into the same area, which often results in messy wiring.
CL Racing F7 FC
Kakute F7 FC
It’s a personal thing, not everyone has the same taste in FC layout.
“All In One” (AIO) FC & Integration
An “All In One” FC has in-built power distribution and will have large pads for the heavy gauge wire for input voltage directly from your LiPo. The term was originally used back when it was standard to have a PDB to regulate power to your FC, but with the variety of components found integrated with FC’s these days, it has become more misleading.
One of the first components to be integrated with the FC was On-Screen Display (OSD) – Betaflight OSD.
Other integrated circuitry that has proven invaluable is the Current Sensor: it’s a much better indicator than VBAT for when you should land and great tool for testing – More about current sensor and calibration.
Other commonly integrated components include Barometer and magnetometer (compass).
There is no “true” all-in-one solution (not yet anyway), but you can find almost any component – RX, VTX, even ESC’s – integrated with the FC.
The RacerStar Tattoo F4S FC was the first ESC integrated FC I reviewed, although it wasn’t very reliable.
4-in-1 ESC & AIO FC?
4-in-1 ESC’s are common these days, and are often designed as part of a “stack” for use with a specific FC, usually a 4-in-1 ESC acts as the PDB. The plugs and connections from a 4-in1 ESC to the FC are not standardized so ensure your parts are compatible before you purchase.
Can an AIO FC and 4-in-1 ESC be used together? Yes they can, but we don’t recommend it.
Depending on the type of ESC you want, use an AIO FC with separate ESC’s.
A Non-AIO FC should be coupled with a PDB for individual ESC’s or a 4in1 ESC.
Mounting Pattern
The mounting pattern is the hole distance in a flight controller. Common mounting patterns are 30.5×30.5mm, 20×20mm and 16×16mm. The mounting pattern is largely determined by the size of the board, and the size of the aircraft it’s designed for. 5″ and larger aircraft normally use 30.5×30.5mm while anything smaller use 20×20mm. 16×16mm are getting popular with micro builds under 100mm.
Other Flight Controller Features
Blackbox: Flash Memory or SD Logger?
Blackbox data is useful for tuning and troubleshooting.
There are two ways to record your blackbox data – storing your flight logs either on an SD card or integrated flash memory.
Flash memory is cheaper to use, but it’s also very limited in terms of how long you can record. Depending on your logging rate and the amount of flash memory on your FC, you can usually only capture 10 to 20 maybe minutes of flight data. It’s also extremely slow to download, taking up to 5 mins to download a one-minute flight log.
Flight controllers with a built-in SD card reader allows you to insert an SD card allowing you to record for weeks without worrying about running out of space. It’s also very fast to read the data, take the card out and you can access the logs immediately.
Blackbox logs are really for more experienced pilots to diagnose almost imperceptible issues with flight characteristics, such as racers looking to squeeze out every last drop of performance. For the averaged hobbyists, perhaps this is unnecessary unless you are really into tinkering.
If your FC doesn’t have SD card slot nor flash memory for blackbox, you can get an external SD card reader (Open Logger) and connect it to your FC via UART.
Connector Types
The three main types of connectors on a flight controller are
- Plastic JST connectors
- Solder pads
- Through holes
Plastic JST connectors are less durable although they allow you to connect/disconnect wires more easily. Solder pads are more robust, but you can run into risk of tearing them out when stressed or overheated when soldering. Through holes are flexible as it gives you the option of direct soldering or using header pins.
- Pro Tip: How to remove header pins on a FC.
- Pro Tip: With solder pads, did you know that it’s possible to fix them if they peel off?
BEC (Voltage Regulator)
The majority of FC’s provide a regulated 5V pad. Some even provide 9V, 12V or some other voltages. These voltage regulators are often referred to as “BEC” (battery eliminator circuit).
Although a lot of FPV gear (FPV camera and VTX) can now be powered directly from the LiPo battery, I have found it produces better results powering them from a regulated power source.
Learn about how to wire FPV setup to reduce noise.
Camera Control
A feature that allows you to configure FPV camera settings using your radio transmitter and Betaflight OSD. Learn more about camera control here.
Boot Button
A boot button (or bootloader button) can put FC into bootloader mode when pressed. This allows you to “force” flash firmware in case normal firmware flashing doesn’t work (why use bootloader button on FC).
Originally FC’s provide 2 solder pads for you to bridge when bootloader mode is required, a boot button makes it much easier.
Left: Boot Button; Right: Boot Pads
Soft Mounting
Soft mounting is a good practice to reduce vibrations transferred from the motors to the gyro. There are two main types of soft mounting when it comes to mounting flight controllers: rubber standoffs and grommets.
Learn more about FC soft mounting.

If I send you a board picture of a Flight Controller, would you be able to recognize the manufacturer?
Ultimately I’d like to be able to connect to the controller safely and read it’s settings, but I don’t know the software to use.
I thought I could contact the OEM and see if they would recommend how to “safely” change controller values myself.
Thanks so much Oscar!!!!
This article really helped me understand a lot about how to build my own drone.
Greetings from Argentina.
This is a really fine article! Thank your for your in depth research and attention to detail!
I found this article while searching for references to an idea that I have. I would like to take a ‘stock drone’ with some descent specs like brushless motors, good batteries, long range Tx, and refined frame (I have an Altair Aerial Blackhawk for example) and upgrade to a programmable FC that I can add sensors, FPV, OSD and GPS.
What FC would you recommend for this? Would I be able to bind it to a stock Tx that comes with these drones? Even if I needed to add a dedicated FlySky or similar Tx/Rx would it be possible? Thanks for any feedback.
Hello.
I would like to have a DJI Mavic or Robotics EVO drone, but they are way too expensive for me.
I’m looking for something smaller than a Phantom or a Xiaomi Mi, but with obstacle avoidance and followme option and around 30min range.
Instead of buying an expensive branded model I could try to build one myself with a DIY kit if it has the same specs but it’s cheaper.
What set kit or spare pieces would you suggest to build it?
Desired specs:
30min flying time.
5km range.
Max Altitude at least 300m.
Foldable or small size. (like Mavic or less).
Optical stabilizated camera or gimbal.
FPV.
GPS.
Sensor avoidance.
Followme option.
I prefer smoothness to speed.
It never cheaper to build your own. There is no way to get those features for less money than a mavic.
Oscar Liang,
I have read pages of information like this and tried to understand it, but with no luck. You put all your knowledge in the perspective of a newbie asking all kinds of stupid questions and your orderly and very sorted-out narrative is helping a lot. I bet you dont get too much nice feedback and what you do is free and come with no ties attached, on behalf on the community I am deeply grateful for your work and others who are contributing as best they can.
Great read,
I have query.
Can i use a Any flight controller for any size drone.
Example: The same Flight controller on a 2.4 Kg drone and a 24 Kg drone ?
I’m asking this because the ESC, Motor power rating will go up, so will the same Flight controller be able to function.
Sir ! I am building my first Quadrotor. I built the custom flight controller using Arduino Uno and MPU-9250. I have written PID Algorithm for single axis stabilisation of Quadrotor. But, the Quadcopter is not at all balancing. and it is oscillating always. Can you please help me regarding my issue. Can you please say the meaning of Max. Effective Gyro Sampling Frequency. Can I attain stability if I switch to MPU-6050 instead of MPU-9250 ?.
Please help me, sir
Thank You.
This is great information on the differences in flight controllers. I have the DYS F4 pro for my MCQ Fusion, and really like it. I’m trying to help a friend resurrect his hex-copter and would like to find an F4 FC that will support a six motors, and has a betaflight OSD. Any recommendations?
The XSRF4O we just reviewed recently can do what you ask :)
Please advise me,
I have built my first quad and I have a little problem with the KK 2.1.5 board that I am using. When load increases i.e, when I increase the throttle the KK board restart. When I checked for the voltage the it restarts when the voltage drops to 6.1 volt. Is there a particular voltage for the KK board to restart ?
Hello,
I have a KK board, but I’m having second thoughts. Anyone suggest a simple FC for basic flying, not racing…yet. Just something that connects to Comp for settings, can hook up FPV and an HD cam. I have a 450mm frame. I don’t know if this makes a difference, but I’d like to connect a gimbal at some point. Maybe by then I would just get an upgraded FC.
Thank you.
What is the name of the controller in the grid at the top of this page that is in the top left corner? I have one and I cannot find documentation on it because it was given to me without it!! Please help.
that’s the KK2
A very old FC.
Who designed/created the first flight controller board for multrotors for hobbyists?
It’s a mystery :)
hii i am looking to build a drone for real time mapping would you be able to tell be which flight controller should i use?
What about kk v5.5
Hello and thanks for the great post. I am wanting to create a drone to do maintenance work on skyrise buildings and it will need to work in close proximity to the building without hitting it (1 or 2 meter range). Do you have any advice for flight controllers for the following;
a) Human operated with collision avoidance so it doesnt hit the building, or
b) Computer operated with collision avoidance
Many thanks in advance.
Which FC is more suitable to lift payload of 5lb even though they are not placed in balanced positions and lift platform 4 feet off ground
Hi oscar,
Great post as usual. so oscar, i would like to know whats the difference between apm and pixhawk? are they just like the naze32 and flip32(flip being a naze clone)?
thanks in advance
Here: http://intofpv.com/t-difference-between-apm-and-pixhawk
Hi guys…. Question: Do you think that Jiyi P2 is bad alternative ?
Hi Oscar,
This explanation has been both instructive and confusing for me when trying to choose an FC. I am currently building an ImmersionRC Xugong V2 Pro folding quadcopter. I want this as a backpackable hobby (i.e. not professional) video/photo “follow-me” quadcopter when I am walking in hills/mountains etc.
I seem to have two options – either a normal RC Tx control or (my preference) a Tablet control. I don’t need FPV, racing or acrobatic capability. Either way my FC board has to have GPS capability – either internal or external. But I’m not sure which is the best route. I’m capable of hardware/software setups within the Raspberry Pi/Arduino arena – but with all the other possibilities of things going wrong when assembling a quadcopter from scratch – I probably would like to start with a known quantity as far as the FC is concerned. At this stage I’d rather start with a budget board -see what happens and then go up the ladder as I become more knowledgeable as far as capability/ease of use etc is concerned.
it sounds like you should be looking at the APM / Pixhawk route, however I am not familiar with that area yet, currently i fly mostly acro boards :)
Hi Oscar
Please advise me
I have a flip32 and need to connect to a X8R receiver. The receiver connects with Sbus as well
Can I use a Sbus to cppm decoder to complete my setup. Or what can I do
Thankx
yes a SBUS to CPPM decoder is probably the simplest solution for you, and should work fine.
Hi Oscar,
I want to build my first quadcopter i hav got all my materials but struck wit the fc ..my only specification regarding my quadcopter is that it must be completely flexible for me to control it in any manner .like for ex: it must not just fly and land but also perform all acrobatics like flip ,inverted flight ..I hope u got me …. i was suggested a KK v5.5 FC ,,wil this work or should I use some other …mail me if any suggestions ..
Kindly help
Is this a good FC? http://www.banggood.com/Naze32-Flight-Controller-With-32-bit-STM32-for-Multicopter-10Dof-p-953849.html?p=OY2106728901201408U4
I will make my own quadcopter but ik don’t know which stuff I need, I am a novic. Can you help me?
HI Gust,
yes it should work fine with Cleanflight firmware :)
by the way, I recommend joining this forum, it’s very useful and there are lots of helpful people there. I am a daily user too :) http://intoFPV.com
hi oscar, i want to make a quadcopter with gps and camera so which flight controller i can use?
Hi Oscar,
I know this article is some how old, but I am building a quad 450 and I am thinking on the APM 2.6, AM 2.8 or the OpenPilot CC3D Revolution Revo 10DOF STM32F4.
Wandering if you can recommend one, links to vendors:
APM 2.8:amazon.com/Hobby-Ace-Apm2-8-Controller-Absorber-Multicopter/dp/B015CPDD4W/ref=sr_1_2?s=toys-and-games&ie=UTF8&qid=1452720299&sr=1-2&keywords=APM+2.8
AMP 2.6: amazon.com/Andoer-Flight-Controller-Multicopter-Quadcopter/dp/B00Q496EOM/ref=sr_1_1?s=toys-and-games&ie=UTF8&qid=1452720493&sr=1-1&keywords=APM+2.6
CC3D Revo: banggood.com/OpenPilot-CC3D-Revolution-Revo-10DOF-STM32F4-Flight-Controller-Staight-Pin-p-1000068.html
I really appreciated your help.
Hi Oscar,
Perhaps you could has the Pixfalcon and Pixracer ? They are Stm32f4 series.
Thanks for your great and outstanding blog.
Hi Oscar,
I’m building a F550 hexacopter and I have the motors,ESC,propellers,frame and battery, but I don’t know how to choose a good and cheap flight controller.I’ve seen the APM 2.8 and Flip32. Which do you recommend?Or another model?.I’d like to include a GPS or telemetry in the future to have the option to return home.
Thanks.
if you want GPS and return to home, APM or Naza is your friends.
So I’ll buy APM 2.8, will be ok a transmitter and receiver with 6 channels?
Thanks.
Hi Oscar,
Will be possible with Apm 2.8 with gps M8N to have return home and fail safe with 6 channels transmitter and receiver.I read that is also possible the option of follow you, What is necessary for this?
Thanks.
Hi Oscar,
I am presently building a DJI 550mm Hexacopter. I presently have a quad that I picked up used. It came with 1000Kv motors, 30 Amp ESC a KKK2.0 Flight Controller board.
I would like a FPV Setup with all the options available from the start…GPS, Compass and the “Return To Home” feature, and so on. Most suggest the Naza system. I see others also but don`t know were to begin.
All I want to do is fly over trees and record the video.
Thx.
yea… both Naza and APM are good choice for GPS…
Hi Oscar, here is Oscar too!
Thanks for sharing those valuable informations. I just wanna know about SLT protocol and those FC, is there anyone compatible with ? I have this Tactic TTX650 with TR625 Rx and I’m intending to use a MultiWiiPro or a Naze32 Full in a RoboCat 275. What do you think, will it work?
Cheers!
Hey Oscar ;-p
sorry i know nothing about SLT!
Hi Oscar,
I think its wrong to bad mouth someone you have never dealt with on the word of people who might have alterior motives. I am of course talking about your timecop comments. I had a defective naze32 when he first started producing them and he sent me a replacement , no arguments, only asked if i would mind sending him the bad board back so he could see what went wrong. Recently i bought four afromini’s and he sent me a free acro naze32. You have to remember that his forum was never meant for people like me(hobbyist) but as a base for stm32 development types. I agree he doesnt suffer fools gladly but as long as you read the manual first and try to solve your problem yourself first, he is fine. He has always treated me with respect and courtesy and most people he is short with ask him stupid questions that normal people would google first. When he first developed the naze32 it was a clone/reworking of a Chinese 32 bit board called FreeFlight and he really didnt want to go into production full time as he was just a hobby flyer who saw the limitations of 8 bit technology and wanted to move on to a 32 bit FC’s but within the multiwii community. He developed Baseflight from scratch and the naze32 grew from the FreeFlight board. Its a hobby to him, he never wanted the naze32 to get so big and take up so much of his time . If you check back to his break with rcgroups (who treated him abysmally) he makes it clear he doesn’t need the money or the hassle involved , its just a hobby project that grew out of hand. In the beginning there was Open Pilot with 32 bit boards that cost £100 there was no choice then. Now because of the naze32 and its derivatives i can get a board for less than £15 And its better, and mainly because of timecop. So dont knock what you dont know !
Hi Ray, thanks for your comment, and sorry if I hurt your feeling. I was totally just describing what I have observed, none of my words about Timecop are personal. You are right, he did some amazing work about Naze32. Please see Baseflgith VS Cleanflight for more information.
Hi Oscar, been a while since we chatted. XD
Nice article. I know it’s old, so it’s probably expected to be a little out of date.
There are also some very valid DIY boards for those who are not afraid of such things. FlyingF3, DiscoveryF3 and DiscoveryF4… several. Of course, the Sparky series are actually opensource, same as CC3D was, and you can even have the boards made on oshpark.com, buy all the bits and pieces, solder them on yourself and VOILA, a homemade Spark v1 or v2. XD Except, when I checked, it costs pretty much the same if you’re doing 1-3 boards anyway, so may as well just buy a ready made one.
My advice to newcomers is to watch aliexpress.com for sales on the Sparky v1.1. They can be had for about $26 – $28 if you wait and watch. I’ve bought two this way. You could pay half for a CC3D clone, and that will get you flying, but it won’t do GPS return to home, or anything like that. Naze32/Flip32 10dof will, but there are features that already are not supported on them, and most are crappy clones anyway. True that what I got off aliexpress are clones, but I can vouch for the fact that the quality is good, and performance is noticeably better than any F1 board. Can’t beat that value.
Great info, thanks so much :)
I need to update this post, but just haven’t got the time yet :) soon, my friend, soon…
Hi Oscar,
I want to build a quadcopter with the following specification : FPV, Sensor and Tracking( gps system).. which FC should i use to make the quad witht he above mentioned specs.
Plz reply ,or email me… any help or suggesion would help me.
NOTE : A quadcopter that has GPS + FPV + Tracking sytem! .. All in One bro ;)
APM? Crius AIO Pro?
What do u suggest according! …
the FC should help in Tracking as well as sensing part.. FPV is an ad on.
It should help me stabilize my quad..!!
This will be my Final Year project,,,so plz suggest ur expert ideas :)
Hi Oscar,
I am currently in a Senior Design group and our project revolves around a quadcopter. In our design report we need to describe and outline some possible decisions between Flight Controllers, and your post has helped immensly in that regard. I would like to ask if we could use your chart/list (with credit of course) in our report?
sure that’s fine :)
if you could credit back that would be great !

is good the CC3D from Banggood for a 450 quad?
yes, the cc3d is good for 450 quad too!
Please also note, that APM/ArduCopter has a much improved Acro Mode since 3.1 – when comparing it to Multiwii it feels nearly identical. You are right though – on earlier implementations before 3.1, Acro Mode on APM was not so good! :)
cheers, thanks! :D
The Brain FPV has integrated OSD hardware which is handy, butvery little market share for some reason.
It was released last week. Of course it has little market share.
“Sparky, Quanton and Brain FPV Flight controllers were all based on OpenPilot’s project.”
This is not correct. Naze32 is based on MultiWii, being a 32-bit port of MultiWii. Sparky, Quanton and Brain FPV are using Tau Labs firmware which is a fork of OpenPilot.
