man.. I hope not!
BTW guys, I built a normal HPI diff and it's super smooth, doesn't slip and holds its settings! unlike the one that came with the kit.
I think it's the grease i used on the original diff. I used trinity "purple stuff" It's really really thick grease and i think that made the diff slip and made it feel very viscousious.
I just used normal white grease and it's super smooth!
anyone recommend ultraloning up a spur gear?
Also, don't you guys find RRP aluminum pinion gears go bad fast?
I have 4 different ones and the teeth get banged alittle only after few runs
