Hi bbellfly
I wanted a photo of the end of the wing so I could determine if it is symetrical. A symetrical wing, when viewed from the end, with an imaginary line drawn from the LE to the center of the TE deviding the wing into two halves, has an airfoil shape at the top halve as well as at the bottom halve; thus the name symetrical. From your photos I am GUESSING that your wing is not symetrical. If it is flat it can sit flat against the flat fuselage. If it is symetric or simi-symetric, the TE must be raised so a line from the LE to the TE is parallel to the top of the fuselage. The wing appears to be much larger than it needs to be; it may belong to a larger plane. Or maybe the plane was meant to be a 3D plane. Those planes fly a bit different than "standard" planes, and the difference is accepted to get the 3D features. I suggest you contact the person who built the plane to get advice. Also, compare it to designs on spadtothebone.com. The short tail makes this plane difficult to trim in pitch. Increasing the horizontal tail area by 50% may give you the needed improvement. I recently was forced to do that with the vertical stab on my SPAD CoroCub to correct a tendency to nose over during landing.
