Just put my Rc Car Gearing app on Android market :-D

Nifty, but can you add a bit more variance to the pinion and spur options. Like 30t min and 70t max for the spur and 10-30t for the pinion?

I am guessing by interval gears in the settings screen you mean internal gearing in a transmission, like a revo has for example?

Cool, I like it.
