Gear Speed is a comprehensive and efficient gearing tool designed specifically for brushless RC car enthusiasts. Unlike slow web calculators with limited features, Gear Speed offers a user-friendly interface and powerful calculations to help you achieve maximum speed.

With Gear Speed, you can easily calculate your maximum speed, RPM, final drive ratio, and rollout. The app allows you to store your setups and include notes for your runs and setup changes. Additionally, you have the option to email this information for permanent record keeping.

Gear Speed supports a wide range of inputs, including pinion size, spur size, transmission ratio, tire diameter in inches or millimeters, motor KV, LiPo cell count, and cell voltage. The app has recently been updated to handle LiPo batteries ranging from 1S to 12S.
