FAQ

What does Gear Speed do?

Gear Speed is a dedicated tool for brushless RC cars that calculates maximum speed, RPM, final drive ratio, and rollout. It helps enthusiasts optimize their gearing for performance.

What information do I need to use the app?

You will need to input your car's specific information, including pinion size, spur size, transmission ratio, tire diameter, motor KV, and LiPo cell count and voltage.

Can I save my RC car setups?

Yes, the app allows you to store your custom setups for different RC cars or configurations. You can also add notes to each setup to track changes and performance during runs.

What battery types does it support?

The app supports a wide range of LiPo batteries, from 1S up to 12S, allowing for calculations across various power configurations.

How can I keep a record of my RC car's performance?

You can email your saved setups and run notes directly from the app. This provides a permanent record of your car's configuration and performance data for future reference.
