Abstract

A model airplane comprises a flat wing and a member connected to the wing midway between the wing-tips and near the back of the wing which extends away from the top surface of the wing. A freewheeling vane is connected to the back of the member and spaced-apart from the top surface of the wing.

Claims

1. A model airplane comprising:

a flat wing with two wing-tips, a front, a back and a top surface;

a flat stabilizer connected to the wings generally midway between the wing-tips, the stabilizer extending perpendicularly away from the top surface of the wing and extending from near the back of the wing towards the front of the wing and having a rear edge; and

a freewheeling vane connected to the rear edge of the stabilizer and spaced-apart from the top surface of the wing, the vane being rotatable by air about an axis which is generally parallel to the direction of flight of the model airplane, whereby, after the model airplane is tossed in said direction, the vane lifts the front of the wing so the wing planes the air and the airplane flies in a loop, returning to a person who threw it.

2. A model airplane as claimed in claim 1, the wing being uniformly flat.

3. A model airplane as claimed in claim 2, the stabilizer comprising a rectangle, elongate in a direction perpendicular to the top surface of the wing.

4. A model airplane as claimed in claim 3, the wing being elongate in a dimension extending between the wing-tips.

5. A model airplane as claimed in claim 1 or claim 4, the wing and stabilizer comprising expanded plastic foam.

6. A model airplane as claimed in claim 5, the vane being propeller-like with a relatively small pitch.

7. A model airplane as claimed in claim 1 comprising a weight connected to a projection extending forwardly from the front of the wing.
