This Gym Stick is so called because its fuselage is a carbon fiber tube, and it is sized to fly in a Gym.  I have flown it in a couple of indoor soccer venues. The wing span is 28 inches, and the wing is made of 3 mm Depron polystyrene foam, warmed and rolled over a pipe to form the airfoil. There is a 40% Kline-Fogelman strip ( http://theparkpilot.org/kline-fogleman-airfoil-design ) under the wing's leading edge.  The Gym Stick weighs 7 ounces, and wing loading is 5.2 ounces per square foot.  It is guided by a light weight radio control system, and the motor is a 16 gram out-runner type, turning a 6 inch propeller. The motor draws 36 watts With a 450 mAh 2S battery, and produces about 8 ounces of thrust. It would fly, but feebly, with a motor of one half the thrust, so I'm looking forward to trying to fly it again.
