The remote control model car, referred to as RC Car, is a miniature version of various real racing cars. It has the same mechanical principle as the real car, similar structure and handling characteristics, and amazingly amazing super sports cars. speed. RC Car be divided into two categories according to the power source. The first type is the "EP RC Car" driven by the battery/electric motor, and the second is the "GP RC Car" for the power output of the internal combustion engine. According to the proportion, there are 1/28, 1/18, 1/10, 1/8, 1/5. For example, 1/10 means that the size of the model is about one tenth of that of a real car. RC Car can be said to be a high-tech product. It is widely used in many advanced materials and technologies, such as carbon fiber, titanium alloy, and aviation aluminum. It is a very common part material in remote control cars. Moreover, the latest electrical/electronic technology, digital technology has also been applied to the remote control car for the first time.

The aviation model, as its name implies, is a model aircraft made in accordance with the shape of the aircraft. It belongs to the aerospace model and is an unmanned aircraft for sports. The aeromodelling movement is a highly technical sport that performs outdoor activities, training competitions or record flights by manipulating, flying, or assembling model aircraft. Modern aviation model movements are divided into five categories: free flight, line manipulation, radio remote control, simulation and electric. According to the power mode, it is divided into: piston engine, jet engine, rubber dynamic model aircraft and unpowered model glider. The maximum lift area of the aviation model is 500 square decimeters; the maximum weight is 25 kg; the maximum working volume of the piston engine is 250 ml. The aviation model competition subjects include: time left, flight speed, flight distance, stunts, "air combat" and so on. There are currently 30 projects in the World Championships, held every other year. The aviation model also has a record project that records the absolute scores.

The nautical model refers to the model of ships and warships, usually refers to model making, competitions, exhibitions, and performances in sports. It is a science, military, sports, cultural and educational activity. Through the production of models, competitions, exhibitions, performances and other forms, we can learn about the various knowledge about ships, navy and oceans and improve their overall quality. The nautical model is a scientific sports project that learns nautical science knowledge through research and production, manipulation of various models on the water. There are many types of nautical models, and the methods of classification vary. According to the rules of the NAVIGA of the World Maritime Model Movement Federation, the competition models of the nautical model are divided into five categories: Power boat nautical model (M), engine circum-powered racing and radio-controlled single-boat or multi-ship racing racing boat model. 2. The simulation navigation model (C) only evaluates various models such as ships, equipment and construction scenes. 3, durable racing boat (FSR), radio remote control, according to the special competition venue, the route in a longer period of time, the collective racing speed of the racing boat model. 4. Sailing model (S), which is a model of a radio-controlled sailboat. 5. Simulated navigation and navigation model (NS) The navigation model projects carried out in China include: simulation model, power boat model, sailing model and performance model.
