Primmnz,
Make sure I have this right..
Span squared = 9 ft
Wing area = 15 ft
So my aspect ratio is .6.
So I am worrying about nothing!

Da Rock,
While this has the proportions of a delta it is a backwards one. Any Idea how that may effect the flight characteristics?

dick,
With this design I am ggoing to be going from a thickroot foil to a thin tip foil, with the top of the wing flat to provide dihedral.

Please check out odball design 101 in the scratch build forum.
All comments welcome!
