Ratings and Reviews
Good tool, could use an update
Good tool but lacking some basic things that would take it from good to great. There’s no way to reorganize your list, which would be really nice to group models together with different gear and tire setups. I’d really love to see a master car list with a sub-list of available gear, tire, and battery options.
As a quick and dirty tool, this gets it done.
Very useful
Very useful but could be a little better. Using this for drag racing I am pulling down to 3.4 per cell and I can’t duplicate that.
Needs work
I'm only giving it 3 stars because I tricked it to work. Need a way to set differential gear ratio. I tried calculating speed of new xmaxx. Found several calculators that work great online and figured I'd try the app. The only way I managed to get the app to produce close to accurate speeds was to set cell voltage to 3.75 and cells on 2. I'm appalled that I paid for an app that isn't actually accurate when it's marketed as a calculator.
