My R9D recently had a problem. After many flights totalling about 10 hours the Rx went into failsafe damaging the plane. The odd thing is it didn't recover from this failsafe condition until I eventually cycled the power on the plane. I knew the Tx was ok as I tried it with another model including a failsafe recovery. Has anyone else had this issue of the receiver completely locking up until its power is cycled? I've repaired the plane but can't chance using this radio if it could happen again. My guess is that the designers have omitted a "watch-dog" circuit to reset the program counter in the event of The R9D's microcontroller program crash. Am I correct? Ed
