Great Planes windows on a Goldberg Cub?
The Goldberg cub is narrower than the great planes or H9 cubs.
The windshields are vacuumed formed and not a flat sheet as on the quarter scale cubs.
The windshields from the Great planes 40 Cub, and the Hanger 9 are identical except that the GP one is made of thicker plastic.
The side windows are different on all three cubs, but you could get away with using flat acetate sheet.
