What pitch for spurs & motor mount???

I just bought a Hyper 7 and a GS Storm SUT, and was wondering if 32P pinions work on these spurs? or what is everyone else using. I've never done a truggy or buggy before so it's kind of exciting for something new.

I don't like metal to metal and was also wondering if anyone makes nylon or plastic gears for these spurs?

I haven't even got my Hyper7 yet but did a quick mock up of the Storm SUT. I have'nt seen any Storm SUT's on here. I guess it's that old huh. Here's a pic. I figure a 10L (since I had one laying around), MM, UBEC & a 3S or 4S Lipo.





I was also looking for a motor mount for the Storm but couldn't find one yet. Is the Revo one probably the easiest to use?
