Work in progress
The Revolution is a full 10DoF flight controller board capable of stabilizing various aircrafts ranging from small racing miniquads to large FPV fixed wing models and aerial photography platforms.
Along side standard stabilization modes it also supports various GPS assisted modes and GPS navigation flight.
