[E-Revonut]

Do some shopping on ebay! You can usually pick up a set of four axle shafts for about $20. Some spare arms wouldn't be a bad idea but I drove a nitro revo for a year and e-revo for over a year and I think I broke 1 set of front arms and one set of rears. A set of axle carriers wouldn't be to bad to have but I only broke one and that was when I hit a pole doing about 40MPH. It wouldn't hurt to have a couple spare shock parts or a like 2 whole complete shocks, it's nice that they are the same on all four corners, just different springs. Many like the Tekno sway bar kit and say it improves handling a lot.

If your running the 7 cell batteries that come with it you will be dissapointed with the runtime, they are only about 3000mah. I have a set that came with my E-maxx, they aren't horrible and if your not geared to high they perform pretty well, I did pick up a set of the Traxxas series4 7 cell packs and they do real well, actually faster that a set of 2s lipos and close to the same punch as the lipos. I would have to say hold off on going for a set of 3s lipos, you may be surprised with a set of 2s lipos, and 5s seems to be a pretty nice spot on your setup, run a 3s on one side and 2s on the other.
