I have a 40T Revo M1 spur already. Will a 20T M1 pinion mesh properly with the larger motor? I don't have the pinion so I cant even make a guess. The 600XL is 2mm less in diameter than a Neu 15xx. Yeah I'm gonna have a 2:1 ratio on the pinion/spur. That's the only way to get hellish speeds with 35K RPM and 3" tires.
