Quickly and easily get an estimate for your RC car's top speed with RC Speed Calculator Pro! Just tell us which car you have, enter some info about your gearing, motor and batteries, and we'll do the rest.

Record your estimates to compare different car setups, and if you have a speed gun, you can record your actual top speed along with the estimate.

Info you'll need:
- Pinion gear teeth
- Battery cells (or voltage)
- Motor Kv rating
- Tire diameter (we can fill this in based on your car type)

Info we probably have already based on your car:
- Spur gear teeth
- Transmission ratio

Please note, our top speed estimates are just that - estimates! We use a formula that works in theory (in perfect, not real-world conditions), but every car and all driving conditions are different, so expect some variation from real measured speeds.

Ratings and reviews

No more burning up a sheet of paper and using calculator to get your numbers. This app does it all for you. Couldn't be more simpler.

Simply very helpful in finding what gearing to use without having to actually run the car.

Love this app! The estimates translate in real world it's not spot on but it gets you in the ball park!
