Overview: Autopilots and OSD’s for planes and quadcopters

The Autopilot system includes the IMU (compass), GPS, airspeed sensor, temperature and barometer sensors as well as other sensors.  The radio receiver’s signals are routed to the autopilot where sensor considerations are made and then data is outputted to the servos and speed controllers.  It is responsible for the full automation of the whole system…
