EVERYTHING YOU WANTED TO KNOW ABOUT ELECTRIC POWERED FLIGHT

This e-book will help you if you want to broaden your knowledge of electric.
Using a motor selection resource can be helpful too. The Electrifly system works well. I have had good experience with the Rimfire motors.

The calculator will let you vary the prop size, flight character, weight and other parameters. Even if you don't want to use Ammo or Rimfire motors you can get specs that can be applied to other brands.
Using the calculator above and assuming this is a twin engine set-up and assuming the largest prop you can use is 16". I used the calculator for the Rimfire motors.
If the assumption is wrong, just make changes in the calculator
