Gearing help (ZX-5, Xerun 8.5)

[JonMack]

I am a total newbie to 1/10th off road, been racing 1/18th for the last 4 months, but just picked myself up an Atomic Carbon ZX-5.

I was wondering if anyone could give me a hand with gearing? I'm running an Xerun 8.5, and I'm mainly going to be using indoors on carpet, my local track is a tiny micro club but I sometimes venture over to caldicot, so something for a medium sized indoor track would be good.

Also, if anyone has a Futaba servo arm going spare, I am in need of one, I'll happily pay postage for it, if not I'll just buy the plastics kit from JE for £4 :P

Thanks,

Jon
