Ratings and reviews

inches is 10x too small. to get an accurate measurement, 5 inches needs to be entered 50 inches. other than that, so far so good. just been figuring out the mm measurements. pretty accurate

Very easy and intuitive to use. It has been really helpful pairing different spur and pinion gears. No guessing or calculations needed. 0 % or 10 percent change, or whatever change, it shows you.

Very effective app. that is easy use. The side by side comparison of current & desired gearing is the best part. ...Also, I'd like to Thank you guys/girls @ RC Gear Calculator Pro. You've helped me a lot with gearing my ARRMA LIMITLESS ⅐ scale speedrun car. Saved me a substantial amount of time using this app. Again, Thanks - B. C. -
