Nice truck, like any other trucks out there they are not perfect, had to replace the ball cups by RPM heavy duty ones because they where popping off to often, when through front and back differential because they where not shim properly, i'm going to race mine this summer and i want to replace the clucth bell and spur by those ones ,bell [link]http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXLST7&P=V[/link] and spur [link]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLSU6&P=7[/link] i would suggest to replace the brake pad too [link]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXM738&P=ML[/link] like MastaDizasta said i think the weakest point are the C-hubs/knuckles, that was one of the first upgrade i'ved done(to aluminum), there some minor problem but nothing that can't be fixed. Like any other trucks if you abuse it at one point your going to break something. To me it's a very durable truck. I had to deal whit HPI and they have a very good customer service.
