Default 540 Gear Ratio

Can someone please explain to me what changing the spur to a bigger spur does and what changing the pinion to a bigger a bigger pinion does?

Also what kind of gear ratio and final drive ratio for the 540 class?

Thanks

Changing the spur to a bigger one will make your ratio go from ie 6.5 to 8.5 if you go up in the number of teeth. Increasing the pinion number of teeth does the opposite. For ratios for Silver can racing, try a 90 tooth spur with a 50 tooth pinion for the cyclone s, which is around 4.4 It really depends on the track.

Default 540

well going for smaller spur will get higher top speed and getting a bigger pinion will get a higher top speed but watch the temp on the motor!! i run 540 and i have a 69tooth spur with a 33 pinion if that helps??
