The Fiber Glider is made out of Aircraft Grade Carbon Fiber for the fuselage wing and tail. Carbon Fiber is not only stronger than the balsa-wood and plastic used in other model airplanes, but is also light and flexible.
The location of a glider’s CG or Center of Gravity significantly influences the flight characteristics of the aircraft. While the glider is in flight there are three forces acting on it: Lift, Drag, and Gravity. The force of lift acts at the wings Center of Pressure and gravity acts on the gliders CG. When the CG is in front of the Center of Pressure the glider will fly flatter, when the CG is behind the Center of Pressure the glider will pitch up. The position of the CG can be changed moving the ballast thus changing the glider’s flight characteristics.
