Panch, thanks for that, might have raced with you at Caldicot at some point then, although in the past I've mostly raced my X6, only recently really with the B44 really.
The more I think about it, the more I think that smaller is maybe better in this case...our indoor tracks are relatively small, and maybe the motor does gain some heat by running too slow on too big a pinion...not what people seem to suggest should happen, but seems to be the case in practice for me and my throttle finger.
Gonna keep playing and seeing what works for the best anyway, one day I'll understand it properly!
Cheers guys
