My goal is to have the heli RTL when the signal is lost. Since the ESC is directly connected to the receiver, when signal is lost, the ESC would power down. Anyway to get ESC to be controlled by the APM2? My plan is to have the ESC running in governor mode to have a fixed throttle. So APM2 doesn't really have to have any variable control to it. More or less like a toggled signal.
