The Monster/2200Kv combo includes an 18 tooth, 32 pitch/metric .8 mod pinion gear. In a beautiful green tint of course

This is perfect for Traxxas E-maxx's and E-Revo's.

At this time we don't have a gearing chart for the Monster. It is in the works but will be a little while before we have anything concrete. The 22/64 might be a bit much, you may want to stick with the 68 spur with that pinion. You'll also need some good batteries to keep up with the amp draw and the motor will run a bit warmer; Just keep an eye on temps and if the motor stays below 170-180° F, you're good to go. You just might be purchasing more A-arms or bulkheads than before, because it's sure going to be moving with that gearing.
