Return Spring
My one and only WTF moment, yeah right...
I had just fixed my buddies Revo. Had it started and he was driving it around. I needed to swap the throttle servo on mine so we could run togther. A five minute swap right? Only if you forget to hook up the return spring. Unfortunatley, the thing started right up, stood up on the rear tires dragging the wing on the ground and racing across the yard. How I did not break anything is beyond me. Dang that is funny...
