The world's first compatible FrSky, Betaflight ready, born for acro flight controller for the BeeDuctrix/Tiny Whoop/Inductrix quad!

Full Cleanflight/Betaflight compatibility on a STM32 F103 Naze32 style processor. We decided on the F1 processor over the F3 due to less complexity of this F1 design. We also found that there is no need for the higher F3 chip due to the rate and speed that the BeeDuctrix flies.

Fully programmable through Cleanflight/Betalfight using the onboard USB port! Tune all the parameters, PID's, and rates to your perfect settings!

Finally, you can fly your BeeDuctrix style quad in full rate mode (or even air mode!), fully execute flips/ rolls, and shoot the smallest of gaps with precision! Tuned to give you that locked in feeling you get with standard race quads.

We make two versions: FrSky compatible and DSMX compatible. No more hacks or modules named after a certain citrus fruit required, just bind and fly! Please select the option that is right for you when making your purchase.

This board is designed to work with current BeeDuctrix/Tiny Whoop/Inductrix setups, just replace the current board with our new BeeBrain vr.1 board and experience the next level of flight control.

Please note: the Taranis version requires your Taranis to run the US firmware that allows it to go into D8 mode. The EU version of the firmare will not work.

All BeeBrain boards come pre-flashed to the recommended 3.0.1 version of Betaflight. Please DO NOT FLASH to another version

All BeeBrain FrSky boards being shipped are v1.2, and include a new binding procedure. Please see here for details

Frequently Asked Questions

Due to the overwhelming response from the community, we have put together this F.A.Q to answer the most commonly asked questions about our new BeeBrain version 1 board

UPDATE - troubleshooting tips! This section will grow as more and more members of the community give us valuable feeedback and suggestions on how to improve the tune

Difference Found between Betaflight 2.9.1 and Betaflight 3.0 configuration:

If the version of Betaflight you have is 2.9.1 then do the following:

Set ESC/Motor protocol to PWM on the Configuration Tab

Go to CLI and type this in:
set motor_pwm_rate=4000

If the version of Betaflight you have is 3.0 then do the following:

change ESC/Motor protocol to BRUSHED on the Configuration Tab

Go to CLI and type this in:
set motor_pwm_rate=4000

What radio control protocols are used by the different version of the board?

  • The DSMX compatible version uses PPM 7 Channel that is compatible will all DSMX and DSM2 Spectrum radios.
  • The FrSky compatible version uses PPM that is compatible with Taranis radios when set in D8 mode.
  • This is a high-quality Spektrum DSM2 or FrSky S.Bus compatible receiver. It is not an official Spektrum or FrSky receiver. The Spektrum, DSMX and DSM2 brand is a trademark of Horizon Hobbies, USA. The FrSky and Taranis brands are trademarks of FrSky Electronics co.

Can other radio controllers be used?

  • Yes, any radio that can take the Orange Rx version module, such as the Turnigy 9X, is compatible with the DSMX version of the board.

Does it work with D8 and D16 FrSky?

  • The FrSky protocol is PPM so only D8.

Will this work with NanoQX transmitter?

  • Yes it does, it works with any 2.4 GHz DSM2/DSMX style controller.

Can it handle 8.5mm high-speed motors?

  • Yes, the board can run 8.5mm motors, but our recommendation is to use the 6mm size motors.

Can it handle 2S batteries?

  • No, it is designed to handle only 1S safely. Using higher cell batteries can damage the board.

What size are the mosFETs? How many amps can each mosFET handle for each motor?

  • The mosFETs are CJ2302 and each one is capable of handling 2 Amps per motor

What Flight Modes does it have?

  • The board runs the popular Cleanflight/Betaflight firmware that is fully customizable and includes several different modes: Auto-Level, Horizon (auto-leveling mode with ability to flip), and full manual (rate). You can also enable AirMode and be able to control the quad at any speed and attitude!

Does it have Altitude Hold?

  • No, we are focused on making this board the lightest and most agile that it can be, and are excluding extra features such as altitude hold for the time being.

What is the size of the motor micro JST plugs?

  • The board uses the JST 1.25 2 pin style plug. These are also known as the Molex PicoBlade connectors

Can this handle a 400mAh Lipo?

  • The board can handle all 1 cell Lipos of varying mAh size.

I have a Turnigy 9x with the orangeRX DSMX module. Has it been tested with that?

  • The DSMX version of the board works with OrangeRx 1.2 version of the module.

Will this work with Flysky?

  • We currently do not support FlySky or Futaba natively as the first generation boards only support DSM2/DSMX and FrSky PPM protocols.

Is this compatible with the FS-i6?

  • It is not natively compatible, but we are currently testing this radio in AHDS PPM mode.

Does the DSMX or FrSky receiver support telemetry? Or any idea way of knowing the battery voltage?

  • Not for this version of the board, but we do have plans for telemetry in the future!

What else do I need?

  • This is just the flight control board for the BeeDuctrix/Tiny Whoop/Inductrix. You would still need the either all the other parts that make up the quad (motors, frame, battery, camera). We plan on selling the whole kit (unassembled) once pre-orders arrive in September
