Can’t scroll

Spur and pinion chart is glitched after new update.

Completely in accurate

I put in my gearing, kv, battery, ect. Gives me a top speed of 4. The car I can promise does well over 100. App is fake in my experience.

Very useful

A useful app, I find the pill insert reference quite easy to use and the info regarding my brand of car seems to be correct.

Keeps crashing

1 star review as app is not functioning to be able to test. When tapping internal drive ratio app crashes every time

Awesome app
