I'm running hitec servos in my truggy.Steering hitec HS-7955TG works great.Throttle hitec HS-985mg and when ever its powered it makes a loud humm Almost like you have to much EPA but louder after about 15 sec the servo starts to get HOT.I played with different RX ports and still does it.I can get it to stop by applying brake very slowly then once i move it again it begins to humm again????????????????????????????????Any suggestions
