I have the m11x and a 92744 receiver in one car, works fine. I bought a 92451 for another car, copied the profile over from the one car, and set I up with everything 100 percent and zeroed. The throttle works as it should, but the servo centers and won't move. I checked the servo hooked up to the 92744 receiver and it's fine. Hooked up a different servo to the 92744 and same issue, it'll center but not move. Any ideas?
