Abstract
The present invention relates to an improved model airplane for purposes of scientific education and competition. Model airplanes in the prior art are either bad at flying, or do not look like real airplanes; and all are short of a collision prevention device. By means of some special positioning adapters for fixing the wing section firmly to the body and by adding a collision buffer piece to the nose, the model airplane according to the present invention is not only good at flying, but also safe and durable to use. The model airplane according to this invention is, therefore, best suitable for the above-mentioned purposes.

- a body having a nose portion and a tail portion, said nose portion being fitted with a detachable buffer and a hook, the tail portion having a vertical tail piece;
- a wing section;
- a horizontal tail piece fitted to said tail portion;
- an adapter for holding said wing section to said body, said adapter being formed to raise the wing section at an elevation angle in the range 0.degree.-20.degree. with respect to a horizontal plane that is perpendicular to the body, and wherein said adapter comprises a left portion and a right portion, said left portion having tenons to go through holes in a central portion of said body and to fit into corresponding mortises in said right portion, said left portion and said right portion each having a slot for receiving said wing section, and the adapter having right and left sides elevated at an angle in the range of 0.degree.-20.degree. with respect to a horizontal plane that is perpendicular to the body.
