How about those balsa wood gliders that had red and blue printing on the wings, that you had to carefully push apart, assemble and put paper clips on the nose for balance? If you wanted a long flight pattern you pushed the wings towards the tail. Or model airplanes made of balsa that you Exacto knifed to customize the parts, used REAL Testors airplane glue from tubes, then "doped" the wings to tighten the paper. Originally they were powered by rubber bands then advanced to .049 gas engines that would always bite your fingers when they kicked back during starting.
