There are too many different possibilities it can be. I am going to hope my LHS is good to at least attempt to fix my problem especially since this is a constant out if the box problem from what i have heard. Hes a pretty good guy and i dont see why he would not help me out. If worst comes to worse ill just see about rebuilding the whole diff with aluminum parts because i was going to swap the whole car to that anyways.
A lot of people break the diff in by holding one wheel while holding the throttle for something like 20 seconds. Then hold the other wheel and repeat the process.
I'm not sure what you mean by a "kink" in the diff. Have you taken it apart to inspect the gears? I'd do this only after
taking it to the LHS to get them to solve it first. If they don't help, call Losi/Horizon Hobby. They have the absolute best customer service and they might send you out a replacement differential.
Cool. Let me know how you like the Atomic BBII. Make sure that's not installed when you take it back to the LHS.
Currently, there are no metal gears for the Micro-T so the only aluminum piece you can get is the transmission case. And you have to buy shims to use with the aluminum transmission or else your diff will strip. Whoever designed it didn't spec it out right and there's too much play in the transmission. Shoddy Chinese "engineer" at it's best. Chinese engineering...now there's an oxymoron!
