Ive put about 5 flights on my kmp gee bee it flies great with the saito 120 and an 18/4 prop. It likes speed and it is fast with the saito. Takeoffs are just fine with a touch of right rudder needed to compensate for the torque of the saito. In flight the faster it goes the more stable it is it certainly likes speed. Landings are somewhat of a handful just keep them fast on final approach, the airplane slows down nicely. I had to modify the gear as the wheels tend to get into the pants. I used quater inch foam epoxed at the point of the loop in the gear. Pack both sides firmly and it will give the gear some dampning that it truly needs. I also put a copper bushing made from tubing and cut with a dremel tool to tighten up the wheel and used a ring lug as a standoff to keep the wheel off the wire. You will surly enjoy this bird and it will sure turn heads at the field believe me its not that hard to fly youll love it.. Good luck Bill M e-mail me if you have more questions..
