RE: 42cc engine with EI & Lanier Ulimate Pitts Question?
Don't have any worries about the weight vs. wing area. Due to the size of the plane, the reynolds numbers stack up really well even with a wing loading as high as 36 oz/ft. She flys sweet!!! It's the ONLY bipe that I've flown in the actual aerobatic category that's a "floater" The higher wing loasding has little, if any, noticeable effect in it's handling if the balance is correct. It blows the wings off an equal sized Pitts or Eagle, and lands better than a slightly larger Ultimate of similar weight. This plane slows down extremely well for the approach. I made more dead sticks with the engine I had than I care to remember and making the runway was never a problem. There's a lot of people that watched and probably still can't believe it would slow down and float that well. It really is that nice of a plane!
For the elevator servos, those are pretty big elevators, so I believe 70 ounce servos would be the minimum.
