I received these Squirrel pictures from George Clarke who lives in Surrey, BC.
I thought you might be interested in this version of your design. Wingspan – 36 in. Chord – 3 in. Length – 34 in. Weight – 36 grams. Not too bad with respect to wing loading – approximately .3 g/ sq. in. With 2 loops of 1/8 rubber powering a 15 in. carved balsa prop, it just pokes along with the prop turning fairly slowly. It will probably require a third and possibly a fourth loop of rubber to really make it go. I put a slight vee dihedral in the wing. Cheers, George
