I have a 90" Great Planes J3 Cub. I recently discovered that the outer 2/3 of the left wing has a 1/4" front side upward twist. This plane is a flying plane, but poorly flying that is. Can anyone tell me if there is a technique to "un-twist" this wing????? I am fearing that I will ultimately re build the wing in the future but for now I am just looking to try and pull some of it out. I am also thinking that I can pull a little out by adjusting the struts on that side. All comments are greatly appreciated.
Thanks
