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 with M2/M3 screws. What’s more, two sets of M2 and M3 screws + silicone grommets are included in the package!

I really like this radio but I had a gimbal stick pull out without any pulling on it. I've had this happen with other name brand radios so it's not a surprise or let down. A little super glue and right back at it. It feels great! I love the full sized gimbals! I have the zorro and the boxer but I think this one is the right fit for me.
Handy as a second transmitter for travel, tiny whoops, etc
Surprisingly good for the price especially with ELRS. It has just enough switches that I can do most of what I can with the TX16S, and it's so much easier to throw in a bag and go. My only wish is that I could put the thumb-grippies style of stick ends on it easily (and still remove them for storage), but maybe someone will come up with an adapter or similar. Next step is to try a Gemini ELRS nano module and see what kind of range is possible on that.
