Surely the Dihedral is set by the centre ply piece which you build out from? The jigs as far as I could see just supported the trailing edge to ensure it is level chordwise when sheeting.

Well whatever I did, my wing is dead straight as far as I can see. No warp, no twist, no wash in or wash out or anything.

Lets just hope I can build the ailerons straight as well[8D]

You never know, I may end up with a completely straight plane. That would be a first !![sm=lol.gif]
