Need help with my G3-build

1. Possibly- smaller spurs like that would be used with smaller pinions, so the pro diffs would be better **I think**- the calculator will answer that question better than I can as there are many gearing possibilties.

2. No issues there, it'll eat them all alive whether bashing or racing- the instant backflips will have them silly nitro lovers pooping themselves with fear.

3. No person who speaks German could be evil... (your English is better than most English speakers on the traxxas forums to be honest).

Specs sound great really for those lipos, price is pretty much what I'd expect from a good brand, so you should be be fine with them. Careful with some lipo-savers though, as they arent designed to work with cars that have forwards-brake-reverse throttle, only boats or planes/helis with forwards and brake only throttles. Post up the link if you like, there are a few german speakers around here and babelfish does a good job of translating web pages.

4. The traxxas 17mm hubs are fine so far as I know, just a little pricey I think compared to the various other options- 17mm is 17mm at the end of the day though, so its better than stock 14mm and gives lots of options with regards to wheels and tires etc.
