We have been flying combat with swizzle sticks for 26 years now. We fly in the Poconos on Gov't land. It's the Balsa USA stick 40 with no ailerons. We all fly with 46 size engines and a stock fuse and wing. Some have foam wings that stand up to a terrific beating. I make those wings for $28.00 each. I am considering purchasing a laser cutter ( I'm a sign maker) to make stick 40 ribs so guys can make spare wings or repair damaged ones.
