When I landed, it returned to normal. I started moving the rudder and the throttle servo started cycling again.

Sometimes, when many servos pull lots of power, the voltage can drop momentarily and create the fail safe condition.

Frankly, I'm happy for what happened to me. It was my Majestic and my control surfaces were moving really slow when I landed. With 9402s and 9204 all around, they should have been snapping.

Anyway, why take chances. Get your radio checked out and sleep better when it comes home.

Ciao,
