For any modelcar driver/mechanic, is fundamental to know the ratio and/or rollout on the car setup, for optimal performance of the battery and motor.

With RcRatio, you can calculate quickly and easily the values for ratio, rollout, and max speed. Also you can get the charts for ratio and rollout.

You only need to set some values like spur, pinion and internal ratio to get the data.

Also you can save your settings for later reference.

It works for speeds on MPH and KMH, you only need to set up on the settings menu.

Its on english and spanish.

Mph must be wrong!! Theres no way my losi22 only goes 8 mph, bad calculations
Hard to use
The sliders are too sensitive. Please change the sensitivity or convert them to "Wheels" like the Timer in the iPhones Clock App.
Great… Except for two things
Love this app—It’s very logical and takes account for every factor of gearing (tire diameter, internal ratio, etc). However, there’s two problems: 1. The sliders are too sensitive, while the little gears at either end are inconsistent and not sensitive enough. 2. When I try and save a setup, the app asks you to name it but it won’t display a keyboard to let you do so. All my setups are unnamed, and therefore confusing. Despite these hiccups, it’s a great app and I’m always figuring out ratios for my friends at the track. Thanks.
