Abstract: An automatic elevator control for improving the flight performance of power launched gliders. The elevators of a model glider are connected by a transverse axle pivoted through the fuselage, having a projecting lever arm. The lever arm is connected to an elastic band with the opposite end thereof adjustably connected to the fuselage. An upper limit stop is provided with the tension from the elastic band holding the lever arm against the stop. The elevator position is adjusted to a normal glide position for free flight when the lever arm is against the stop. During launch from a catapult or sling shot, the inertial and aerodynamic forces on the elevators overcome the tension of the elastic band causing the elevators to assume a level position. The glider can therefore be launched essentially vertically without looping and climb to a maximum altitude in a relatively straight path.
