Choosing an electric power system.. There is an APP for that

[JASO']

Hi guys , I found an app recently that allows you to choose a motor, esc prop combo purely by inputing your aircraft parameters and flying style. It's called EASpec and available in the APP store for about a dollar. It works spot on every time and saves so much wasted time in trial and error with trying to match a prop with the right size esc so you dont fry it.
I highly recommend it and for a dollar you can't lose and you will not be disappointed.

Just tried it with some specs for some planes I currently have. Came out pretty close. I just have to convert the metrics.
