Ok guys, I need some help. I have a new Spektrum DX3S, and using it with my Slash everything works fine as it should. Wanted to use it also to control all my nitro rigs, I wired up a rx, binded it, and went through all my setups for steering and throttle. The steering works fine, however, the throttle servo seems be receiving mixed signals as the servo doesn't move freely and makes noise. The servo is good, and have tried other servos and they do the same thing. The sr330t rx is good also, and I've tried a different rx, having the same results. Anyone have any insight as to why I'm having problems with the throttle and brake servo? Everything works fine on the steering input on the rx, but nothing will work correctly on the throttle and brake servo.

Thanks!!!
