Simple question, what's the gearing on the 3800kv now? Have you fiddled with different gearing to suit the conditions? I ask because the 3300kv in my SC10RS is plenty potent for most tracks, when geared right.

Certainly better motors are out there, but you might be able to make this one work for ~the cost of a pinion or two.

...Unless you've already explored that of course.
