It was strange for me too. I am running a JR 10X and JR 950S receiver. I had done extensive pre-flights, so I am sure nothing was binding. The other channels were working perfectly. I just sent the receiver in to Horizon for a checkup. The servos were returned to me yesterday. Amplifiers in both were damaged. Damaged motor in one. Damaged gears and case in the other. One servo was replaced the other repaired. I would think some of the damage was done in the crash.
By the way, I want to thank you and Hitec for your quality and speed of service. Dale
