Abstract: A rubber band driving device for two-propeller model plane, mainly comprising a power rubber band 1, a wooden skeletal bar 2, a rubber band winder 3, a rubber band locator 4, a power distributor 5, transmission bars 6, support bars 7, a left propeller gear box 8, a right propeller gear box 9, propeller blades 10 and 20, a propeller space locator 30, and a propelling direction adjuster 40, wherein the power rubber band 1 is connected to the rubber band winder 3 and the power distributor 5, and the power stored in the power rubber band 1 is transmitted, through the distributor 5 and the transmission bars 6, to the left and right propeller gear boxes 8 and 9, to set in motion their blades 10 and 20. The driving device disclosed in the present invention is reasonable in structure, stable in work, easy to maintain and repair, and is suitable for various kinds of two-propeller emulation model planes.

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.
