Been tinkering with gas engines for about ten years and still don’t know anything for sure, You are right about different props giving more thrust with same rpm,

Trouble is the props are not cheap, Spent over $200.00 last week alone them.

Also been working with electrics for about three years and there is were you can get confused, Amp draw, Voltage under a load, Watt in watts out. And on and on. No wonder people get confused when they have never set one up.
