Sooooo handy
Glad I got it being new to on road

This utility app simplifies the calculation of final drive ratios for RC cars. It allows for offline calculations and provides insights into how different gear ratios affect acceleration, speed, motor load, and battery life.

[1.1.1] -Chinese version updated
RC-GEAR calculates the final drive ratio using the formula: [No. of spur gears x No. of Pinion gears x Secondary gear ratio]. This allows for quick and easy computation without needing manual calculations.
Yes, RC-GEAR is designed to be used offline. This means you can calculate your final drive ratios and analyze their effects anytime, anywhere, without needing a data connection.
RC-GEAR explains how setting to low gear (high numerical value) results in faster acceleration but lower top speed, reduced motor load, and longer battery life. Conversely, high gear (low numerical value) leads to slower acceleration, higher top speed, increased motor load, and shorter battery life.
Yes, RC-GEAR contains advertisements. As a free utility, ads are displayed to support its development and continued availability.
RC-GEAR is available for iPhone, iPad, and iPod devices. It is designed to run on Apple's iOS ecosystem.
The latest version of RC-GEAR is 1.1.1, which was last updated on April 25, 2022. Updates typically address bug fixes and minor improvements.
RC-GEAR has an age rating of 4+. This indicates it is suitable for users of all ages, with no mature content.
While RC-GEAR helps you calculate and understand the effects of different gear ratios, it's important to note that some motors and ESCs have their own recommended gear ratios. Always consult your specific RC car's manual or manufacturer guidelines.
