Hey guys i have the Futaba 3pm tx and a R603FF receiver, at the moment the receiver is running on rechargable AA batteries which would equal 4.8v.The manual states it needs 6v.The reason i am asking is after landing a jump it takes a few seconds until i can get control again and also today the throttle stuck open a couple of times over fairly flat terrain but it shut off after a few seconds of doing so, my batteries are fully charged , all connections are tight and the fail safe is set, it has always done this so was just asking has anyone else had similar problems that a 6v upgrade sorted out , thanks
