I want to be a model plane in the future ... what department should I choose? ...

Hehe, interesting. I will be a senior next year, and the idea of applying for the exam was similar to yours. The major I am studying now is aircraft design (a few professional universities such as Beihang University, China Southern Airlines, Harbin Institute of Technology, Northwest Institute of Technology, Beijing Institute of Technology, Shen Hang, Changhang University have this major, and some schools like Zhejiang University and Xiamen University seem to have related majors. Please check the relevant information for details). I also participated in the school's model airplane team and participated in the national model airplane research competition. The general feeling is that you don't have to major in aviation to play model airplanes, but you really know model airplanes after learning this major. This "understanding" requires you to reach a certain level of knowledge and skills to understand. Generally speaking, you will learn aerodynamics, flight mechanics, structural mechanics, material mechanics, elasticity mechanics, aircraft overall design, aircraft stability and maneuverability, which is the theoretical basis for you to play model aircraft. But in fact, as long as you study engineering, your knowledge base is basically enough. If you want to play model airplane, it is good to read relevant professional books. Don't be discouraged when playing, but if you really learn aviation, you should also regard aviation as your career ideal while playing. There are many excellent talents in our team, who will eventually study for a doctorate and eventually work in national scientific research institutes. There are also very few people who are tired of playing with things. Please grasp it yourself.

In addition, model airplane sports are very, very expensive, so please consider it according to your family situation.
