Thanks Loswave. My main concern was the balance, but as you say shifting the other gear around will sort that. Im off to one of our big rc shows tomorrow and hopefully ill pick up everything there. As for the motor decision, i may go for the inrunner if i can find a decent quality gear box to attach it too, if not i may go for the outrunner, but ill just see what they have and keep you posted.

Thanks again for everyones input

Joe
