My suggestion is to bind you reciever and radio again while having your throttle in the idle position. If signal is lost, it will return to this position. I had problems one day and was not happy about spektrum until I realized my on off switch was bad. Even if your switch is working right now, I would replace it regardless. It's a cheap item. I nice stout throttle return spring would be a good idea too. I use the one off of the Adam Drake Gas Truck. It comes with mounting loops and two springs. Good luck!
