Many unmanned aerial vehicles are being researched and developed in modern times and are being operated in various industries. Unmanned aerial vehicles (UAVs) and unmanned aerial vehicles (UAVs) have a wide range of applications in the aviation industry. They are also used in conventional unmanned reconnaissance aircraft and unmanned fighter planes for disaster monitoring, relief, meteorological observation, Aerial photography, entertainment, and the like, and is expanding to include more fields.

Among the currently commercialized unmanned aerial vehicles, especially multi-copter equipped with multi-rotor, there are two types of multi-copter, which are police, unmanned disaster prevention, aerial shooting industry, and toy toys. There are many problems to do.

In industrial use, there is high price from 50000000000000000000 to 20000000000000000000 and the risk of taking off weight is 15kg ~ 100kg. In case of toy, it is inexpensive and stable compared with industrial use. However, Only technology can be learned. Therefore, it is necessary to educate professional multi-copter operators inexpensive and safe, and to provide training materials for specialized multi-copter operator education. In addition, conventionally, the boom is folded in order to reduce the volume or to facilitate the movement of the multi-copter, especially the helicopter, so that the power-supplying wire is loosely formed in the structure Due to the characteristics of the helicop, which receives direct sunlight at high altitude, the electric wire is cured, which may cause a fall accident due to electric power supply failure due to long-term storage or wire failure.

The multi-copter currently on the market is divided into quad, Y6, hexa, octo and X8 depending on the number of motors used and the number of boom (axis). It is impossible to change to another type of multi-copter.

The skeleton of the flight device of the Korean Unexamined Patent Application Publication No. 0812756 (2008.03.05), which has a structure of a conventional unmanned aerial vehicle, is a frame in which a body and a boom are fixed, It is impossible to implement a frame of the type, so there is a disadvantage that it is necessary to prepare a spare part or to secure a surplus gas in preparation for an unmanned air vehicle crash when using it for education or industrial use.
