Brushless Revo or brushless CRT .5 help is appreciated

[BrianG]

I have a CRT.5 as well and absolutely LOVE the way it drives! However, since the selection of hardened pinions to use is limited at the moment, I was stuck using a hardened 16T pinion and that was geared too high. So, it's on a shelf right now also awaiting a plastic spur.

A 12 or 13T pinion should work well on either of those motors, assuming the stock Mod1 pitch.

If using the 4600, I would use 3s if it's available. If using the 5700, 2s should be fine.

Being so small, the CRT.5 is an easier conversion and can use less expensive components.
