new to racing got a b4.2 need some help

[sur3fir3]

well I built my b4.2 took about 3-4 hours was easy build, much easier than any 4x4 I've built from a kit. My question is this. what stock parts should I have as back up. of course I know I need a few sets of arms, but other than that what has broken the most for you on this rig. I will be running 17.5 blinky class, so i wont be going stupid fast or anything.

thanks

I would get RPM arms and bumpers. I would also get an extra pinion and spur as well as a couple extra bearings of each size.

rpm doesn't have any arms for the b4 series on their site, I only see it for the b3... anyone know if they make em even?
