Too difficult to access the
USB port on your compact
2-4″ quad? Say goodbye!

It’s time to say goodbye to this trouble! With this Bluetooth
stack, you don’t need to connect your quad to the PC for
FC and even ESC tuning, everything can be done
wirelessly in the SpeedyBee app.

Tune Flight controller
and ESC wirelessly!

Power the quad, connect the SpeedyBee app via
Bluetooth, configure the UART Ports,PID,OSD and
every other settings on this flight controller.Also,
every parameter of the BLHeli_S ESC in this
stack can be set via the app.

Change motor directions
wirelessly!

With this stack, when you finish your build, connect to the
SpeedyBee app, change the motor directions just in
a few simple steps. Then take off.

Support DJI Digital
Video transmitter.

The flight controller has two
independent 9V 2A BEC and
5V 2A BEC, supports various
analog image transmissions
above 5V, and also supports
DJI Air Unit / RunCam Link / Vista.

Real 35A ESC, no false labeling!

6-layer 2oz PCB plus optimized circuit design equals stable
and strong current output. The four-channel continuous
140A output can reach 30 seconds.

*Test result comes from SpeedyBee laboratory.

M2 or M3? Why not both?

Have you ever experienced that the stack
holes of your frame did not fit the stack
you got? This stack is perfectly compatible
