Best you FIRST check the amp draw with the initial prop that you want to use ... if its within the range that is safe for the system then fly her and test with different props. Flying is the only way to know which prop suits you and/or the plane. You want to use a baseline guide for the power. You want something like 150W/lb at the least for IMAC. Now you are talking watts/lb based on AMP DRAW and not what is at the prop. So if you plane is say 12 lbs, you want to touch about 1,800W. I enjoy the XOAR E props and feel they got more bite than APC-E ones.
Attached was my MidWest CAP 232, she weighs in at about 15 lbs and pulls 2,300W ... only good for sport flying. Verticals are nothing to shout about. So that gives you an idea as to how much power you want.
