Decalage Angle
Posted: Fri Mar 10, 2017 9:40 am
Hi all, new member here. Six months ago purchased Skyboy EX with 100 HP Rotax. High wing pusher fabric wing and tail.
Very short version for very long issue -
My instructor didn't like flying characteristics of this airplane at first. Airplane is flying straight in level with a very high angle attack. I am flying by myself now, and I think I am getting used to it, but still don't like it. After doing a lot of homework I and up discovering that my decalage angle is 9 1/2°. another words, when airplane is sitting on the perfectly level ground, which is supposed to be straight and level flying attitude, the wing is pitched up by 4 1/2°, but tail pitched down buy 5° negative. Gives me a total of almost 10° differential between two surfaces. I am Cessna trained pilot. It feels to me like I am flying around with fully extended flaps.
Does anybody have a knowledge in this area?
