Great app

I love that I can save multiple setups and add notes to each setup. Worth all 99 pennies
Pretty good App.

Great for seeing how gear adjustments can effect overall speed. Useful as a good guide for the numerous variables that contribute to performance.
Incorrect Info

I'm putting information in that it's asking for. My rc is completely stock and I have used gps to find speed. This app is roughly 20 mph off.
Can’t select gear type ?

The app is excellent except for the most vital component, being able to to choose the gear type whether they are 48pitch or mod 1 gear size for example. That allows you to further calculate speed otherwise your calculations will always be off to some degree. Please fix this as all of my calculations were wrong, I found this out after I purchased a GPS and did a few passes on 4s on my rustler 2wd. Please fix, once corrected I will pull my review and re-do.
Glitches

You put everything in correctly but it tells you your car will only do 3 mph. The app hasn’t worked right in a day now
Wow...
