From what I had read, I agree with it just being another point for leakage. I'll take it all apart eventually, probably whenever I get the itch to mess with it again. I just have my electric cars and they work and pretty low maintenance, just shocks and diffs for the most part, so easy to keep running. I wonder if maybe the flywheel wasn't on right from Traxxas and that's why I had issue's leaning it out and it bogging down and not shifting. I also noticed temps skyrocketing after one or two pulls like right after the break in period, maybe it was binding up or catching. I'll have to take the motor out so I can get the flywheel off and see. Thanks for the help.
