I've put the sheeting on the wing. On Friday, I'll cut the wing in half and trim it for dihedral.
The problem is that neither the plans nor the instructions from this late '70's kit tell me how
much dihedral there should be.

Wingspan is 50". It's the Flight Dynamics, Inc. (FDI) kit.

If you'll tell me the wingspan of your plane and how much each tip is up, I can figure the
dihedral for my plane.

Thanks!
Mike
