AlienFlight F3 Hexa Brushless V2

The AlienFlight F3 Hexa Brushless V2 is an experimental flight controller designed to pilot small brushless powered Quadcopters – Hexacopters. It features an ARM STM32 F3 processor, side USB for easy firmware flashing, and parameter editing, MPU6500 Gyro/Accelerometer, and built in bind/boot switches for hassle free binding/flashing.

This AlienFlight board can run Open Source CleanFlight Or Betaflight Firmware.

NOTE: You’ll need to switch from brushed to one of the brushless ESC/Motor options available under the configuration tab.

* Most Spektrum Compatible DSM2 satellites work out of the box. DSMX sat should also work with DSM2 protocol with default settings. (DSM2, 11bit, 11ms is preset).

NOTES: Battery Voltage monitoring is disabled by default.

Lost Model Alarm: A small Buzzer with a low current draw (=<20mA) can be used in place of the VMON LED. You can tie activation of this Buzzer to a switch on your Transmitter via the Beeper option, on the Cleanflight modes page.
