The industry is not the firstrate in the world. The development of toy industry of China is limited by many factors, such as design without innovation, lower quality standard, manufacturing no strict technology and with primitive methods. The reverse engineering (RE) is one of the most effective design methods, which has shorted the cycle of the product design with promoting the quality of products. The method has widely used many industries on aboard. Sheet metal design of automobile has applied the method in China. But the toy industry of China has hardly used the advanced method. Toy design with RE can cost less time and promote the quality of toys. This paper redesigned a toy airplane used a motor with REM under CATIA software, which is one of the most advanced soft of CAD/CAE/CAM. The design has these steps reversing the model, constructing points cloud, modeling the CAD model, modifying some outer forming and inner construct. The airplane has more beautiful on appearance and more reasonable construct. This paper also designed the mechanical system of the airplane.
