spur gear question
would like to ask if what will happen if i install a 48t spur gear on my truggy(Hobao st)the hyper st has 52t spur on it and i just want to try putting the 48t spur,and i wonder if my engine would be really stressed with the 48t?i know the hyper truggy is a bit heavy but i have done some mods to lightened the truck a bit..
