Description

Ratio Calc is a quick and easy tool for radio control car racers to use trackside. Knowing your final drive ratio (FDR) is very useful for comparison with other racers to determine if your car is geared correctly.
It lets you quickly select your car by filtering on manufacturer and model. Select your pinion and spur size and the FDR is displayed. Tyre diameter can also be entered to calculate your rollout.
Ratio and roll out charts are also available which plot pinion and spur gear combinations to create very handy reference tables.
- Save your favourite cars for quick access
- Select measurement units (imperial/metric)
- Select your preferred gear pitch, alternative ratios in other pitches will be shown
- Over 2000 cars/variants in the database which is updated regularly

In a sea of mish-mashed, garbage R/C related apps, this is an aesthetic oasis. It does exactly what you downloaded it for and doesn't give you a migraine in the process. What more do you want? Hmm. Maybe a watch app? Oh yeah, the dude made that too. Excellent work.

My go to gear ratio app

Does exactly what you need it to do; quickly figure out gear ratios and rollout. Saves your individual cars and their settings. Buy this app for gearing, you won't be disappointed.
