I BOUGHT A XOAR 22X10 AT THE TOLEDO SHOW AND RAN IT ON A ZENOAH G-62 IN A T.F. GIANT P-51. THIS PROP TURNED THIS PLANE INTO AN ABSOLUTE FIEND, TOP END AT LEAST 40% FASTER THAN WITH A ZINGER 22X10, PROP RIP EVERY TIME I THROTTLED UP, AND VERTICALS ALMOST TO THE LIMIT OF RADIO RANGE. (I ENDED UP BAILING OUT OF THE VERTICALS SEVERAL TIMES) IT IS VERY OBVIOUS XOAR INT'L HAS DONE THEIR HOMEWORK ON THIS PROP. NO DISAPPOINTMENTS HERE. BEAUTIFUL FINISH, NO BALANCING REQD, AND BOLTED RIGHT UP (10MM HOLE).
