I use APC, Zingers , and Master Air Screw. On every plane I try alot of props, sometimes even the Master Air Screw will give me what I'm looking for, though they break, too easy. That must cause a danger at some point.


P.S. The "old timers" say a two blade is more efficient then a three blade, and on some old super light Free Flight planes the one blade prop was even more efficient then the two blade prop....
Won't that make, the "no blade" prop, the most efficient?
