I will let you guys know about the Traxxas axles when I get them. I swapped new axles and tried the truck. I have no reverse and second doesn't engage all the time. So I'm not going to run it for a couple days till I can open it up. I might have to put the forward only kit on and lock it into second. The tape also came loose inside the rear tires.

The bright side I inspired a couple guys at work to get theirs out and work on them again.
