All in One Flight Controller Comparison
This comparison chart of all currently (April 2021) available AIO (All In One) flight controllers in the "Tiny Whoop" form factor (25.5 x 25.5mm mounting pattern) should help you to find the best flight-controller for your build. To qualify for this list, the flight controller also needs to have an integrated ESC's and OSD. Further it has to fit a whoop frame, except for those flight-controllers marked with a T which are intended for toothpicks and will not fit most whoop frames.
Some of this boards even come with integrated receiver for the protocol of your choice. This is especially interesting for people who want to save the last couple of grams instead of running a dedicated receiver. The weight is the weight of the board itself without the battery lead unless otherwise stated.
Use the filters to find the limit the selection of flight controllers for your build.
Flight controllers that are no longer available for sale will be purged regularly from the list.
What is the best AIO flight-controller?
Unfortunately there is no one perfect flight controller, that will fit all your needs. You will have to find the best flight-controller for your build yourself. I can tell you how I approach the choice of the right flight controller for every build.
How to chose the right flight-controller?
I use the following methodology to find the right flight-controller:
- Decide how many cells it should support - my builds are always optimized for one specific cell count, but you might want to use it with 2s Oor 3S for example.
- Maximum current draw: What is the projected maximum current draw of our build? When you go with 1S this will probably never exceed 5A, but can be a deciding factor for toothpicks and micros.
- Do you want an integrated receiver? I like to have an FrSky D8 SPI receiver on my 1S builds. On Toothpicks and micros I usually go with a dedicated one.
- At this point the list should already be reduced to a couple of options. Now you need to find a balance between price, weight and manufacturer. At this point I prefer to go with a manufacturer that I have had good experiences with.

1 Some users experience the BEC frying after a couple of flights. The board will still power from USB but not from battery. This can be fixed by attaching an external micro BEC. It can be prevented by attaching a 100uF, low ESR capacitor either directly to the XT30 plug or the power pads of the board.
The version 2.1 is the same as 2.0 with the exception that 2.1 comes with a plug for camera and video transmitter.
2 Although rated for 2S a lot of people report that it will not work reliably on 2S - the current seems to be highly overrated.
3 Those FC’s seem to all be produced by airbot and have almost the same specs. The BetaFPV version does not have pins for a buzzer and the iFlight boad comes with pin headers for their own video transmitter.
4 Weight with all wires. RX has diversity antennas, everything is plug and play.
5 Will work on 2S with the limitation that the 9V output for DJI can not be used.
V Comes with a half diamond video transmitter.
T Intended for toothpicks, will not fit most whoop frames.
If you are in the market for a flight controller from this list, I would highly recommend to get an F4, they might be slightly more expensive but you gain the benefit of it being future proof in comparison to the F3. Betaflight will stop the support for F3 boards after version 4.0 so you will not be easily able to upgrade to a newer firmware version.
