How do you make an RC motor faster?

Answer 1

Enable It to absorb more air and gasoline. In the the end it has to have proper fuel/air ration. Also bore kits make engine bigger internally. Better spark plug lighter internal parts etc. weight is a huge culprit other than detonation

Answer 2

You can modify it by putting multiple batteries negative end to positive end together

Answer 3

Well if you had enough experience you could change the gear ratio in the gearbox, or buy a bigger motor.

Answer 4

oil it and try to reposition the shaft so it is lined up with whatever it is powering. Bushed vehicles are not always built very well so lining it up helps a lot.
