NEWS: Racerstar Crazybee F3 Pro 3-in-1 flight controller. The best 20mmx20mm board ?

Recommended Posts

The Crazybee F3 Flight controller was the major Key element of the last excellent 65mm FPV tinyhoop machine such as the Eachine US65 and the URAV UR65. Good news, a new revision is now announced with Crazybee F3 Pro version:

What’s new in the menu ?: now the board is 2S compatible !!!!! Imagine the beast with ultra compact 2S compatible 0603 Motors on a 65mm frame ?. More now they added the UART3 connexion to connect your favoriate smartaudio compatible AIO module. Finally, ESC chips (BB2) are also upgraded to run smoothly Dshot600 !!!!. That’s great. ESC are still 5A (peak@6A) rated. Strong enough for 2S power. The Crazybee is still proposed with two choices of builtin SPI receivers (FrSky & Flysky) where both telemetry and RSSI exportation to OSD are here. It’s definitively the best flight controller available in 20mmx20mm format. 4.2g in total. What else ? 🙂
