I decided on the prospec after reading alot of the stuff on the xb8 website. There seems to be a few problems with the xb8 that need sorting out. The spur gear breaking and losing teeth is a big one that scared me off. but damn the next buggy they produce with the bugs all sorted out will be something. Don't get me wrong there are still things wrong with the mugen, eg. diff 'o' rings leak. and the joint pins in the cvd's come out. But there are easy and chead fixes for them and also so much part support its not funny.
