An earlier statement in this thread was: "According to the power and thrust spread sheet I got from Pe Rievers the 11x7 APC at 11,760 rpm takes 1.03 hp, and gives 6.2 pounds thrust. "
The K&B specs say that the .61 is supposed to be 1.3 HP
What do you think of those apples??
Maybe the MAS 11x7.5 prop can produce the difference of 1.03HP and 1.3HP????

root, those were my rpm numbers taken on a hot day at 4000' elevation with an old 6550 given to me used with who knows how many hours on it. I'm betting yours will do a lot better.
