Flew it today with the Menz 18 X 6-10 Tuned to 7400 Static. Flew well, Motor still on the new side. Burned out the original with a lean run. It was repalced by Hobby Services at a very fair price. Less than what the repair would have cost. I'm going to stick with this prop for now. Not unlimted vertical but Great running.
The 17X8 apc spins in the air with the Goldberg extra 330. Worked great on the GP Giles 202. You can hear the engine spool up but the plane then has to catch up. The Menz has much better grab with this Plane.
