Metallover is not quite reffering to the traxxas diffs. On some of the nicer diffs theres a screw (like the one you use to tie down the pinion) that plugs a hole in the diff cup. Through this hole you can fill oil into the diff pretty neat.
Don't the traxxas diffs have something like that too?
Patrick, you can send your dead servo to me. I like dead servos...
