“Spitfire Wing” one of our first straight wing flying wings. 40 to 60 size. It started with a Sureflight foamy then first, I removed the elevator, then when the wing was cut from the foam with hot wire and templates, all was covered with light fiberglass and epoxy. A sweet wing, the fuselage is a little long though, if too long, it will tumble in a sharp pitch up or down. Scarey
