How to Choose Flight Controller for Quadcopter

The number of mini quad flight controllers on the market can be overwhelming for beginners. This guide explains the important factors in choosing the next flight controller for your quadcopter, FPV mini quad or racing drone.

If you are new make sure to check out our mini quad and racing drones guide for beginners.

I compiled the specifications of all FC’s for mini quad in this spreadsheet so you can compare them more closely.

What is a Quadcopter Fight Controller

A flight controller (a.k.a FC) is the brain of the aircraft. It’s basically a circuit board with sensors that detects orientation changes of your drone. It also receives user commands, and controls the motors in order to keep the quadcopter in the air.

Nearly all flight controllers have basic sensors such as Gyro (Gyroscopes) and Acc (Accelerometer). Some FC might include more advanced sensors such as Barometer (barometric pressure sensors) and magnetometer (compass).

Flight controller is also a hub for many other peripherals, such as GPS, LED, Sonar sensor etc.

Racing drone flight controllers are rapidly evolving: smaller, using better processors and hardware and getting more and more features integrated.

FC Connection

Here is an example wiring diagram how components in a drone are connected to a flight controller.

Flight Controller Firmware

Apart from the different hardware, there are also different firmware you can choose from depends on the application.

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

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.

The 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 a flight controller firmware, you can then look at what controller boards are compatible.

Interface and Configuration

Modern FC firmware can be configured via a computer, smartphone, or even from your radio controller. All FC firmware offers different graphic interface and different set of parameters you can change, so there is certain level of learning curve getting into each of them.

Tuning” is the term we use in the multirotor hobby where we change PID, RC rates and other settings that affects the flight characteristics of the multirotor, in order to get them to fly the way we want.



Currently, you have 4 main types of CPU to choose from: F1, F3, F4 and F7. We recommend getting a F3 or F4 FC for now, as we have reached the limit of F1, and F7 FC are still new and needs time to be improved.

F1 F3 F4 F7
72MHz 72MHz 168MHz 216MHz

To learn more about the differences between F1, F3, F4 and F7 processors make sure to check out this article.

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 examples, serial radio receivers, Telemetry, Race Transponder, VTX control etc.

Each UART has two pins, TX for transmitting data and RX for receiving.

For example here are the UART3 and UART6 on a flight controller. You can assign these UART a task in the ports tab of Betaflight configurator.

The Number of UART’s on an FC

You might or might not need many UART’s, but the more you have, the more flexible it is and more future-proof.

The number of UART’s on an FC 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 even have 7 or more.

F1 F3 F4 F7
2 UART’s 3-5 UART’s 3-6 UART’s 7+ UART’s

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 the newer generation processors, and they have built-in inverters in the chip.

However for older processors such as F1 and F4, require an external inverter to “translate” the signal before feeding it to the UART. For users’s convenience, some F4 flight controllers have dedicated inverters for SBUS and SmartPort so you can connect the RX directly to the FC. Otherwise, there are also workarounds for this, such as using soft serial, or getting uninverted signal from the RX.

If you are running out of UART ports, you can use Betaflight feature “soft-serial” to “create more UART”. It’s a way of emulating UART port using software. But the emulated UART has lower baud rate (update rate) that is not suitable for timing critical tasks such as the radio receiver. And it can also increase the load on your CPU.

Gyro Sensor – The IMU

The job of an IMU sensor is to measure the quadcopter’s movement and orientation. An IMU sensor contains both accelerometer (ACC) and gyroscope (Gyro).

Acro mode uses only the Gyro, while “self-leveled” mode uses both the ACC and Gyro. Since most FPV pilots only fly in Acro Mode, we often turn off the accelerometer. And therefore we normally refer to the IMU simply as the Gyro.

Popular gyro used on a flight controller can be found in the following list.

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

* The MPU9150 is effectively the MPU6050 with integrated AK8975 magnetometer, while the MPU9250 is the MPU6500 with the same magnetometer.

You can find the IMU model number on the chip, for example this is the popular Invensense MPU-6000.

MPU6000 - IMU Gyro Sensor

Gyro and Accelerometer on a flight controller

The Choice of Gyro: Sampling Rate vs. Noise

There are two main properties of IMU we need to consider in a flight controller: max sampling rate, and how susceptible to noise they are (both electrical and mechanical noise).

Currently the most widely used IMU is the 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 MPU’s including MPU6500 and MPU9250 which are noisier despite the higher sampling speed.

Faster gyro is a double-edged sword. with clean signal and power, you can expect the ICM series perform better and smoother than MPU6000 in 32KHz. However with noisy ESC, motor and quad with oscillation, the performance of the ICM gyro will get much worse than the MPU6000.

For example, the ICM20602 on the Raceflight Revolt V2, or the ICM20689 on the Kakute F4, both can run at 32KHz. However it’s reported that these IMU are more susceptible to noise than the older MPU6000 therefore these FC’s generally require soft-mounting and filtering capacitors to reduce the amount of noise getting to the Gryo.

There is also performance difference between different ICM gyro’s. For example, the ICM20689 is one of the worst gyro for our flight controllers, noisy and with a high failure rate. If you had to pick a ICM gyro, go with 20602 instead.

Update (Oct 2019): Since Betaflight 4.1, 32KHz mode had been removed, so even when you are using an ICM gyro, you can only run up to 8KHz looptime. So Gyro choice is no longer related to looptime.

There are some FC with Gyro “soft mounted” on foam in order to reduce vibrations coming from the motors.

Soft mounted Gyro – Kakute F4

Gyro BUS – i2c and SPI

SPI and i2c are the types of “BUS”, or communication protocol between the IMU sensor and processor. It can have a significant impact on the effective sampling rate and therefore 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.


FC layout is where the pins / solder pads are located on the board, and how easy it is connect the components.

Most people only care about the chips and capability of a flight controller, but 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 more superior, as all the pads are all located on the edges, and grouped by the functions. The pads on the Kakute are all crammed into the same area, which 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.

“AIO” FC (All In One)

There are two main types of FC, AIO and non-AIO.

AIO stands for All In One, it means the power distribution (PDB) is built into the FC so you can connect your LiPo and ESC power directly to simplify wiring. It is a misleading name in my opinion, because it doesn’t necessarily means it has everything.

Depends on the type of ESC you want to use, AIO FC should be used with separate ESC’s.

And Non-AIO FC should be coupled with 4in1 ESC.

Feature Integrations

Apart from PDB, there are other features that have been integrated into flight controllers over time to make them more powerful and convenient to use.


OSD is a feature that can overlay flight information to your FPV screen, such as battery voltage and flight time.

More about Betaflight OSD.

Current Sensor

Having a current sensor has been proven invaluable: it’s a much better indicator than VBAT for when you should land and great tool for testing.

More about current sensor and calibration.


Having PDB integrated isn’t enough? There are now FC’s that have ESC’s integrated! This means you can solder the motors directly to the FC which further simplifies building.

The RacerStar Tattoo F4S FC was the first I reviewed that has such feature.

Mounting Pattern

The mounting pattern is the hole distance in a flight controller. Common mounting patterns are 30.5×30.5mm, 20x20mm and 16x16mm. 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 20x20mm. 16x16mm 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, if your flight control supports blackbox logging it normally come with either flash memory chip or a SD card reader for you to put your SD card in.

Flash memory is cheaper to use, but it’s also very limited in terms of how long you can record your flight, usually you can only record 10, 15 or maybe 20 minutes depends on your logging rate. It’s also extremely slow to download the data, it can take up to 5 mins to download an one-minute flight log.

Flight controllers with built-in SD card reader allows you to insert a SD card and you can keep recording for weeks without even worrying about running out of space. It’s also very fast to read the data, take the card out of the reader and you can access the logs immediately.

In my opinion it depends on how much you use Blackbox. If you are crazy about studying Blackbox data, you should definitely get a FC with built-in SD card reader. But for the averaged hobbyists perhaps this is not necessary.

You can also get an external SD card reader (Open Logger) and connect it to your FC with one of the UART’s (serial ports).

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.

BEC (Voltage Regulator)

The majority of FC’s provides regulated 5V. Some even provide 9V, 12V or some other voltages. These voltage regulators are often referred to as “BEC” (battery eliminator circuit).

Although with a lot of FPV gear (FPV camera and VTX) you can now power them directly from LiPo, I have found it produce better result to power 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. 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. With a boot button it makes it so much easier.

Left: Boot Button; Right: Boot Pads

Other features you might find on flight controllers

  • Integrated VTX – the main benefit of it is the overall weight saving and compactness, some even allows you to change VTX settings directly from your FC
  • Barometer/Mag (compass) – these extra sensors are less important for racers and mini quad
  • RX Support – make sure the FC support the type of radio receiver protocol you plan to use, such as PWM, PPM, SBUS, Spektrum Satellite and so on
  • Infrared transponder support – allows you to use IR detectors with the FC directly to measure your lap time in some race events or practice

Soft Mounting

Soft mounting is a good practice to reduce vibrations coming from the motors transferred 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.

  2. Julian

    Thanks so much Oscar!!!!
    This article really helped me understand a lot about how to build my own drone.

    Greetings from Argentina.

  3. Ioannis Moutsatsos

    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.

  4. Juan


    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.
    Sensor avoidance.
    Followme option.
    I prefer smoothness to speed.

    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.

    1. Gotham

      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.

  6. Sai pothan

    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.

  7. Alex Wagner-Jauregg

    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?

  8. Brolin

    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 ?

  9. MT5000

    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.

  10. Asher Flynt

    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.

  11. himanshu

    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?

  12. Keenflyer

    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.

  13. kukumeka

    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

  14. Debo

    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

  15. Dr Colin Lloyd

    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.

    1. Oscar Post author

      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 :)

  16. Nivash

    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


  17. suhaas

    Hi Oscar,
    I want to build my first quadcopter i hav got all my materials but struck wit the fc 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

    1. Oscar Post author

      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 :)

  18. ZukenJ

    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:

    AMP 2.6:

    CC3D Revo:

    I really appreciated your help.

  19. macfly1202

    Hi Oscar,
    Perhaps you could has the Pixfalcon and Pixracer ? They are Stm32f4 series.
    Thanks for your great and outstanding blog.

  20. Pablo

    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.


      1. Pablo

        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?


  21. Giorgio Di Lella

    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.


  22. Oscar Jr.

    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?


  23. Ray Tillman

    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 !

    1. Oscar Post author

      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.

  24. MrSatoV

    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, 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 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.

    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! :)

    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.
