Hi Taurus Guys. Between flying REAL airplanes (F-106s) I continued to upgrade my designs. I wanted more FLAT area on the sides of the fuselage and also position the wing closer to the center of the fuselage for better rollmaneuvers. I also had retractable landing which made a GREAT increase in smoother maneuvering. This was my "Smart Dart" 1972. Col. Chuck Winter
