that's wild. it proves these new systems are not 100% yet. i remember a simular incident many years ago when the first PCM'S came out. a guy had just landed his plane.he got distracted and without thinking he turned off his radio while the motor was still running. the failsafe on the throttle was in reverse and the engine went to full speed and the plane went thru the pits taking out another model then hitting a parked car. close call!. mostly pilot error.
glad no one was hurt in your incident.
