…Model takes off from any position. It was enough to tighten the rubber motor, and two-winged “bird”, vigorously rebounding wings, began the rapid acceleration into the sky.

They were United on one thing: almost all majority rose steadily skyward. The secret of them, probably, and was in its original simplicity, was originally a perfect Union, mass-inertial and aerodynamic forces…
