Hi! im totaly new, I did have a tamiya car (one of the ones that runs on a track) ahwile ago. Im about to enter a Uk based competition with my school that involes constructing a RC car, I remember a guy tuning his electric motor by adding extra copper wire to the 3 electro magnet terminals, adding more powerful case magnets and adding brass connectors. It was quite awhile ago so its all a bit hazy, are there any guides around? (you are allowed to modifiy the engine as long as it remains identifiable)

thanks v much Sonic ^_^
