I made a slightly enlarged slowstick wing out of fan fold, used two halves of a CF arrowshaft for a mini-spar. It worked out really well.

I have so much of this FFF stuff I am thinking of other wings that will mount right on. The only requirement is that it be light and have a root size the same as the stock wing (so I can put the stock wing back on easily). I suppose I could add that it would be nice to keep it R/E rather than requiring ailerons.

Any ideas for different wing shapes? How about airfoil shapes - would a flatter or more undercambered wing work? What is the best way to create the airfoil? (On my first wing I slit the foam then put Probond into the slits and weighted down the foam over a PVC pipe. It created a somewhat peaky undercambered shape - but it still flies!)

I have had a lot of fun playing with different wing shapes, and airfoils on a simple stick type plane. Airfoils are formed by cold rolling Bluecor around PVC pipe... The Polyhedril wings Glide better, and give longer flight times... check out this link

Believe it or not a flat plate wing works really good
