Whenever flying friends take planes out to fly, there is always such a group of onlookers who say that planes are children's toys. Here, it is necessary for me to explain to you more clearly the precautions for flying model aircraft. ...

1. All minors, or people with diseases or disabilities that hinder the production and flight of model aircraft, please make and fly model aircraft under the supervision or help of adults who are healthy and have the ability to read product manuals. Anyone who has difficulty in vision, hearing, body, language and movement, and has a history of allergies to plastics and glue should pay special attention to safety and avoid participating in this activity alone or directly. Anyone who suffers from serious heart disease, blood pressure, dizziness and other diseases that are not suitable for model airplane exercise should not take part in this exercise without authorization, and then decide whether to take part in model airplane exercise after consulting a doctor.

▲ 2. In the process of production and flight, special attention must be paid not to let babies, young children, blind people, allergic people, mentally retarded people and mental patients contact and approach models and parts, tools, glue, batteries, etc. , in order to avoid any possible accidents.

3. In the process of making the model airplane, it is necessary to avoid dark, open fire, dust, strong magnetic field, extremely high temperature, extremely low temperature, closed room, moving vehicles and other environments. After the model is made, the remaining parts and tools should be put into your toolbox, model box or other safe places, and should not be placed or discarded at will.

▲▲▲▲ 4. When choosing a flight site, please choose an empty, flat and safe site. Pay attention to stay away from and avoid areas and dangerous areas with many people, buildings, public facilities and animals. Such as: [1] stations, docks, airports, parking lots, highways, streets, tracks, air routes, tunnels and bridges; [2] High-voltage power lines, substations, factories, building bases and military bases; [3] government agencies, foreign embassies, hospitals, and crowded squares in urban areas; [4] Mountains, reservoirs, rivers, canyons, dense forests and glacier rivers. [5] Forbidden areas and unsafe areas stipulated by military, aviation and judicial departments. [6] Avoid night, rainy days, strong winds, foggy days, snowy days and extremely high and low temperature weather conditions.

I want to remind you in particular that you must pay special attention to safety, the road under your feet and the surrounding environment when chasing the flying model plane. Never blindly follow or chase into the no-fly zone and dangerous area mentioned in Article 4 above, and don't make dangerous behaviors such as crossing rivers and swamps in the process of chasing model airplanes; Climbing mountains, canyons and buildings; Crossing the expressway; Invade private territory; Or other dangerous restricted areas. If you catch up with the model plane by means of transportation, you need to pay more attention to driving safety. (Teach children to find parents at home and teachers at school when they have difficulties, such as a model plane flying into a tree or in the water (remote control rowing boat, the model boat broke down in the water), and never take risks by yourself. )

6. Before flying the model, make sure that the propeller and power shaft are firmly installed. At the same time, there must be no people in the radius distance between the front of the model airplane and the front hemisphere of the propeller15m, so as not to be injured by the accidental propeller.

Pilots should never aim the nose of the takeoff force model plane at themselves or others. Don't take off more than two model planes in a small area at the same time. When flying in the sun, you need to wear anti-ultraviolet sunglasses, and never look at the plane with a telescope in the direction of the sun!

7. When a model airplane takes off or lands, it is very dangerous not to face the model airplane head-on, let alone imitate the method of hand-picking the model airplane in the air adopted by some model airplane experts. When the model plane touches the ground, don't go near to pick it up until its propeller stops turning. Before picking it up, the following measures should be taken: [1] It is an electric model plane, please turn off the power switch immediately. [2] It is a rubber band power model airplane, and the propeller stops rotating until the rubber band torque is completely released. [3] For the model airplane of gasoline engine, immediately cut off the engine oil circuit switch. [4] For remotely controlled aircraft, the power switch of the remote control receiver should be turned off first, and then the power switch and oil circuit switch of the model transmitter should be turned off.

8. Whether taking off or landing, the operator should be behind or under the side of the model plane. Never stand in front of a model plane. We don't approve of airplane model taking off directly on the ground, although many professional airplane model enthusiasts do. But for amateurs, it is very difficult and dangerous to take off in a straight line on the ground to ensure that the model plane does not suddenly change its take-off direction, because it is possible to suddenly change its direction and fly to you or onlookers at any time during the take-off on the ground (this may be due to inaccurate production, unskilled operation, uneven ground or sudden change of wind direction). Therefore, the correct take-off posture is to turn on the propeller, gently lift the fuselage of the model airplane by hand, with the nose facing the wind direction (the wind is blowing on your face) and must be lifted over your head, facing a straight line or slightly raising the nose to a straight line at an angle of 5~ 10 degrees from the horizontal line, and then push forward along the straight line with appropriate arm strength to get rid of it. The correct take-off of a model airplane is also a technology, which needs repeated practice to master.

9. For remote-controlled helicopters, whether electric or oil-powered, airplane model enthusiasts are especially reminded to pay attention to flight safety. Any remote-controlled helicopter must take off and land on the ground, and it is absolutely impossible to operate the helicopter by hand. Never fly in a crowd, because it is very dangerous to fly a helicopter in a crowd or overhead.

10. If the airplane model in the air suddenly flies towards you and it is too late to dodge, remember: immediately lift the clamped arms to protect your head and face, and at the same time take a squat posture. With such rapid protective measures, the probability of collision between the model plane and you can be reduced, and the degree of damage caused by collision can be reduced. Don't run and dodge in panic, because the flying speed of the model plane in the air is very fast!

1 1. When bystanders watch the flight, they should be reminded to stay away from the airplane models that are preparing to take off and landing. When holding a group model flight activity, the organizer shall draw a safety warning line or set up safety warning signs, and inform the participants of various safety precautions in advance.

12. If you choose a remote control model plane, you must first confirm whether the frequency and power of the selected remote control equipment comply with local laws and regulations; Whether it conflicts with the frequency of other remote control model equipment being used nearby; Whether it conflicts with the wireless equipment used by nearby police and military police.

13. Be sure to read the instructions carefully before taking off and practice the basic essentials of remote control repeatedly on the ground before flying. You must know that the fun and enjoyment of flying a remote-controlled plane is great, but it is also risky. Once the plane is in the sky, the remote control is not foolproof.

14. Please note: the model airplane is not a toy, but a special sports equipment in outdoor sports-the model airplane! ! ! Hangmo bar
