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.
