Today i took the tq in the a main with my ft sct. i did have the same problem after rebuilding my ball diff. the problem was the shock limiter. i took them all out front and rear for full drop and holy cow night and day difference. there were a lot of losi guy out there. i did come in the 3rd in the first quail. but after that it was all first. i even dropped a tooth down on my pinion from a 28 to a 26. I was able to run full blast though the hole race with out letting go. It feels so good to win first normally i come in third or 4th. this is a large outdoor blown out track that 1/5 scale run on also every weekend. i was lapping these guy so easy i the mic guy all he did was talk about how i was on fire lol. i hope this dont make ego to big lol.
