The kit motor will be fine for a long time, like everyone you will eventually want to go faster, and then you will get a faster motor, just make sure the speed controlelr can handle the power. It's the same with the Thunder Tiger.
you'll just need a selection of pinions (more teeth = faster), but you will get an idea for which ones you require once we start racing. Pop along on the 5th Feb when we're working on the track, the more the better, plus you will see just how big it is.
