Thats a good question jonski!! So far my truck has held up, I feel that the throttle servo is weak and needs to be replaced with a stronger one. And possibly the steering servo could stand an upgrade to a slightly stronger servo. Also I wished they had put a slipper on the spur gear assembly because if you jump it and forget to get off the gas you hear a grinding sound when you hit the ground I suspect this is the sound of the spur gear wanting to shave off some teeth. So don't forget to let up off the gas when you jump.
