Jeff I would use cover technique to pull some twist out. My wing is one piece toobut it turned out great. I have modeled for years and have straightened severaltwisted wings by twisting it the opposite way too far then cover and slowlyshrink, let go and see where it goes. You may need to shrink more on the topside than the bottom. Like Don said the wing is pretty flexible. Mine got stifferafter the cover but is still flexible.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009now covering and painting21" wheelsLycoming O-235 C2CJay Anderson CloudCars prop 76 X 44Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 17 Feb 2012 07:53:08 -0600Subject: Pietenpol-List: Re: Pietenpol-List Digest: 3 Msgs - 02/16/12

the wing is all together... one piece wingthe other side is perfect..My guess is a trim tab or aileron rigging would work but i don't like it..i thought about the stress part.. and considered that i could add ply to the rearside of both rear spars..the full length.. then they would be the same..i may try the wetting the spar and bracing it in the right position till drythanks for the thoughtsjeffRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jeff, have you checked whether your center section is square? I have a one piece wing and had a similar problem with the right rear corner of the wing sagging. I had used cables to hold the center section in place so I could easily move the wing fore and aft when I was checking the CG. After saw the problem with the corner of the wing sagging, I was so focused on the outboard end of the wings that I hadn't paid any attention to the center section not being square until my EAA tech counselor pointed it out. When I squared up the center section, the outboard corner of the wing came up where it should be. This problem is probably unique to the one-piece wing. Larry----- Original Message -----
