This rendering from Kevin Kimball shows the difference between the best drawings (Bradford, Clements) we could find of the Hall Bulldog vs what we’ve determined the actual wing planform to be (Mirco Pecorari). The “sweepback” controversy was settled long ago by our team, but we did not also realize that the leading edge was incorrect even in the period drawings. Unfortunately, this means that the nose ribs already crafted by Tony Horvath will have to be redone. The good news is we consider the wing planform to be final now, and we will end up with a bit more wing area than we thought. Every little bit helps!
