AlienFlight F3 Quad Brushed V1

The AlienFlight F3 Quad Brushed V1 is an experimental flight controller designed to pilot Quadcopters using 7mm-8.5mm brushed motors. It features an ARM STM32 F3 processor, built in side USB for easy firmware flashing, and parameter editing, MPU6050 Gyro/Accelerometer, 9.5A ESCs, and a built in Bind button for hassle free transmitter binding.

The F3 Quad V1 Brushed can run Open Source CleanFlight Or Betaflight Firmware.
