RE: Taking the dihedral out
For now i'f I was you I would leave the wing alone ,considering its a 2 piece wing with a tube its not a simple matter of just adding a new center piece and going for it unless you want to recover most or all of it .I'd rather see you bolt the wing to the fuse and get rid of the bands before you to take the dihedral out of it.
BTW Hello Mike hope to see ya soon.
