Props are cheap.

I hope you test fly the airplane with all of the props you've bench tested. And then tell us how each performed. What speeds did the airplane actually fly with each prop. And how the airplane speed varied in manuevers like the square 8 or just consecutive loops.

Control line offers an excellent testing environment for just such comparisons. A stopwatch is perfectly accurate to clock speeds, and almost any pilot can easily judge how an airplane slows down in maneuvers.

It would be really nice to be able to put some realworld test results into the thread alongside the theoretical data just listed.

I hope you will report back for all of us.
