i have 2 motors that i use in my car. on is a 15x2 venom fire ball and the other is a standard 540 'silver can' tamiya kit motor.
what sort of final drive would i need for each of these motors?
i'm currently running a 87 spur and 27 pinion that works out to be a 7.03 final drive,but with the 15t motor it has bugger all top end. i havent used the silver can yet,but i will be on the weekend at the track!
what ratios on each motor should i start off with?
