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.

“Rollout" means the travel distance (mm) of a RC direct drive car with one rotation of the motor. It is said that Rollout is one of the important items on the setup.

(How to use)
- Select from three types with two tables to display on the screen from the "Display types" button.
- Tap the button on the top of the screen to open the picker, so select the number of pinion gear teeth, spur gear teeth, and tire diameter to be the center of the table.
- Select the pitch of the selection item from the "Setting" button.
