RE: 3/4 to full throttle no difference while in air????
It will turn a Mejzlik 18-6 @ 8500 on the ground using a Slimline Pitts here at 7000 feet...
Other props turn less..I have used PK, Menz S, Xoar, APC, Zinger....I haven't flown a plane with any of these...My customers like the Mejzlik best....The Mejzlik is the most expensive...
