If the curve stays at virtually the same angle all the way to the top, then the 16x6 would be the better prop option. If it was not raining out today, I'd have put the 16x6 on it and reported back by now, but we'll all have to wait.
Holy cow look what has been up!
Now this thread is getting crazy interesting! Perhaps finding the optimum prop not based on WOT but rather a dialed back percentage throttle setting? Ringing out the absolute maximum system performance and prop efficiency to boot. Now your thinking!
Love it. Stellar spin off concept. Iíll take a second helping please.
