Thanks for all the help, it will drive, it just does not drive well, wheel weight or tires seem to be making it waddle around, put on another set of wheels I had on my FMS FJ and same issue, I think maybe these Axials are not really meant to be upgraded much. No where near as good as the Traxxas TRX4M my son got. His does not look as nice but it is faster and he was able to do all kinds of upgrades with zero issues. Also this is my 2nd Gladiator, the 1st one the ecs failed in under 3 days, local very good Hobby shop replaced it.
