What Is a receiver Failsafe mode?

        A failsafe is a safety feature designed into Spektrum receivers that drives the servo or ESC positions to a preset location in the event that signal is lost. Typically you should set the failsafe so that if there is a loss of signal, the sail is pulled in and the rudder is straight. This will help get the yacht to the side in the case  of a radio fail.
