A simple application for calculating parameters gearing for your RC car.

Features & Capabilities

RC Car GearCalc is a simple yet powerful Chrome extension designed to help RC car enthusiasts and racers calculate essential gearing parameters for their vehicles. Proper gearing optimization is crucial for maximizing your touring car's acceleration and top speed by determining the ideal rollout — the distance your car travels per motor revolution. This tool lets you easily compute key ratios such as the transition ratio, primary drive ratio, and final drive ratio based on your car and tire specifications.

Understanding the nuances of gearing, including how tire diameters affect rollout, RC Car GearCalc offers precise calculations that adapt dynamically whether you're using foam or rubber tires, factoring in wear and tear. Whether you're tuning for quick acceleration or top-end speed, this extension simplifies complex computations for efficient and effective RC car tuning, making it an essential companion for hobbyists focused on performance optimization.

User Reviews

RC Car GearCalc is praised for providing reliable speed estimates and useful gearing calculations, especially given that it's free. Users appreciate adjustable settings and unit conversions. However, multiple users note the inability to save multiple car profiles as a major limitation. Beginners find the app hard to navigate without explanatory tips, and some desire a more appealing interface. Other minor issues include limited spur gear tooth options and unit display preferences. Overall, it serves well for tuning and speed estimation but could improve on usability and features for multiple cars.

Pros

Provides a good estimate of RC car top speed.
Free and useful tool for experimenting with gearings and setups.
Allows switching between metric and standard units.
Includes adjustable settings like gear size ranges and voltage sliders.
Helpful for speed runs and general RC car setup.

Cons

Cannot store or save multiple model/car setups.
Lacks tips or beginner guidance on gear ratios and calculations.
Interface is dull and could be improved visually.
Limited spur gear tooth options (minimum 50 teeth) which restricts some users.
Missing simultaneous display of units (e.g., mm tire size and mph).

I literally love this app and use it all the time to at least get a rough estimate of my rc's top speed. I know it's not going to calculate drag and such, but regardless it's a great app!

Love this App for my 12th scale program. Rollout is a must-know once the max motor load is established. At first I didn't realize the gear size ranges are adjustable. Find the adjustments in the hamburger.
