Rc Car Gearing is an app that will calculate an estimated top speed of your RC Car. This app will also calculate your Final Gear Ratio (FDR), Diff Drive Ratio (DDR) and rollout. All these numbers are valuable when selecting or comparing different motors and gearings for your rc car and will help you to find the optimal setup.

This app is intended for electrical cars but if you want to use it with a nitro car just set the motor / battery option so that you motor RPM will be what you'd expect your nitro motor to rev. Typically 30 - 40 000 rpm in 1/10 and 1/8 scale cars. Then set the rest parameters as normal.

- The app will show the calculated result in both metric and imperial units.
- Future versions will add more features.
