ClodMaxx, I would say that a general list of spare parts to stock up on are A-Arms, front C hubs and steering blocks, hingepins, and linkages (turnbuckles). For my CRT .5 I have about 1 or 2 of all the previously listed parts, except I have 2 full sets of a-arms.
Interesting that you went with an XT8 instead of the new E. Oh well, maybe you can pick up the new E and leave it stock just so you can hit those puddles!
One of my hopes is to finish the Revo truggy I have been slowly designing for a month or so now by mid summer. Then I can test it out, dial it in, etc. After that I'm hoping to make it to the RCM bash.

I might have to carpool with someone because I'll still be only 18 next year (which isn't enough to rent a car).
