(Professional model helicopter refers to six-channel electro-hydraulic remote control helicopter, excluding three-way toy plane. )

Q: The professional aircraft models are 30, 50, 60, 90, 120.

A: This classification is applicable to oil-powered helicopters, which are distinguished according to the power displacement of oil-powered aircraft engines. The bigger the level, the bigger the model. Class 30 helicopters are small oil-powered helicopters, and there are more players in class 50 and 90 helicopters. 120 helicopters are basically aerial photography.

Q: There are 250, 400, 450, 500, 550, 600, 700 and 800 professional aircraft models.

A: We often hear the title of such an airplane model straightener, which is distinguished by the size of the helicopter fuselage. Take class 450, class 600 and class 700 helicopters as examples. The 450-class fuselage is about 65 cm long, the 600-class fuselage is about 1. 10 m long, and the 700-class aircraft fuselage is about 1.35 m long.

Q: At present, there are professional brands of remote-controlled helicopters on the market.

Examples of a large number of brands are as follows: AHF Fengshen, ALIGN Yatuo, JR, Shenlong, Tian Zi, Ely Q, Jingshang, Lei Hu, Black Hawk, Boxi Lubao, Shi Jing, RJX, Xianhao, Huake, Taishi, Gulang and Aite. The store hopes that players will boycott Japanese goods and support domestic development. The safety of aircraft depends on the quality of electronic equipment.

The direct selling price of Fengshen 50 SV-3G aileron-free oil is 2 195.00 yuan.

Q: How high can a remote-controlled helicopter fly?

A: Theoretically, as long as there is electricity, the air and the pitch angle are greater than 6 degrees. The simple explanation is that the helicopter model does not turn off, and we push the take-off lever through the remote control, so you can fly freely in the atmosphere within the signal range of the remote control. More than six remote controllers used by professional airplane models, with a remote control distance of

Within the range of 400 meters-1500 meters, it is very small for the plane to fly 300 meters away from us. It can be said that the flying distance has exceeded the visual distance. Generally don't worry about flying far enough.

Q: How fast can a remote-controlled helicopter fly?

A: I haven't tried it accurately either, but the speed of flying 80 kilometers per hour is guaranteed. The helicopter has enough power. As soon as you step on the accelerator, the distance of 200 meters will pass in a few seconds. Fly whenever you want, suit yourself. Don't forget that the biggest feature of a helicopter is that it can stop spinning, find a point in the sky and fly forward a little bit. If you don't want to fly forward, you can't fly for n hours. joke

Q: What is F3C and what is violent 3D flight?

Answer: F3C is a professional language for model airplane competition. Simply put, it is a fixed-point route that flies gently, hovers, moves slowly at a fixed point, and has prescribed actions. F3C has more than ten prescribed movements, and the competition results are judged by the stability and accuracy of the movements. Generally, players say that F3C flying means gentle flying and practicing hovering. Stores also support F3C flying and basically do not blow up planes.

3-D violent flight is to make any rotation in all directions in the air, which is dynamic and three-dimensional, very dangerous, easy to explode but very good, with high technical requirements and needs money to support it.

Q: How much space does it take to fly?

A: It is not a fixed-wing aircraft either. It takes tens of meters of runway to get off the ground. If the technology is good, it can fly as big as a basketball court. For safety, the store requires that the bigger the venue, the better. Flying in crowded places is not allowed. The model helicopter is very dangerous, and the store strongly advises players to leave the plane and surpass it.

10 meter distance ensures that when you lose control, you hit the player.

Q: How much does the plane weigh?

A: It also depends on the weight of the engine and electronic equipment and the size of the aircraft. Generally speaking, the 700-class nonstop plane is probably

About 3500 grams.

Q: What kind of fuel does the remote-controlled helicopter use? Is gasoline okay? Can I match it myself?

A: Generally speaking, the model burns special model fuel. If you don't want to buy it at the model shop, you can buy it at the local chemical reagent shop. The flying ratio of castor oil is 4: 1. Four parts of methanol is the fuel, and 1 part of castor oil is used to lubricate the engine. If we burn gasoline, we don't use that kind of machine, so we can't. If we unplug the igniter, the engine will shut down. If you use a special type of gasoline engine, the gasoline engine alone will cost more than 3000 yuan. If you match a set, it will cost tens of thousands, which is not suitable for novices, and the price of accessories will be higher in the future!

The proportion of methanol contained in Ann is 65,438+05%, 25% and 30%. Generally, 65,438+05% methanol fuel is used, and more than 30% is used for competitions.

Q: What are the components and materials of the remote-controlled helicopter?

A: The complexity of remote-controlled helicopters is far greater than that of fixed-wing aircraft. The fuselage, remote control, engine, gyroscope, starter, igniter and battery are all necessary. There are only 30 bearings in the fuselage, which are made of stainless steel, alloy, copper, aluminum, ABS nylon, polycarbonate and lead. Unlike other toy helicopters and fixed-wing aircraft, almost all of them are engineering plastics or wood.

Q: Is the metal helicopter resistant to falling?

Answer: Just like the bumper of a car is not made of metal, it needs to break down some impact when it hits, and so does a helicopter. There are many vibrations in flight that need accessories of different materials to solve. If there is a heavy landing, nylon material will minimize the impact. As for the metal helicopter, in this way, the fuselage may not be deformed at any position, which will cause the following flight hazards. You can ask the man who fell from the metal helicopter. It's strange that the screws don't drop and the vibration doesn't occur!

Q: How long does it take to learn to fly, and how can beginners practice so as not to fall off the plane?

A: The training frame is a light cross with certain elasticity. It sticks to the tripod of the plane and flies with the plane, reducing the chance of the plane falling and breaking. Beginners can be equipped with a training rack, which costs tens of dollars and is not expensive. We often say that we are not skilled in flying, and the wrong switch causes the propeller of the plane to break when it hits the ground. If you have a training rack, that's it.

Flying below 2 meters, there is something wrong with the rudder, and the rotor can't land, so the plane won't break down. After flying skillfully, it is the same operation method to take off the practice frame and fly 2 meters high and 20 meters high.

Q: Is the propeller made of iron?

Answer: When an oil-powered helicopter is flying, its main rotor can reach 1800 rpm, with centrifugal force.

200 Jin, it can't be made of iron anyway. At least at present, the main rotor of helicopter is not metal. The common main rotor is made of more than three kinds of balsa wood, and the hardness of the leading edge is greater than that of the back balsa wood. There will be lead bars in the middle of the blades, which need to undergo strict dynamic and static life tests before leaving the factory. Metal is absolutely impossible and there is no scientific reason to fly. At present, carbon fiber paddles are the best on the market, followed by glass fiber paddles and wood paddles.

Q: Can I hang the camera?

Answer: of course, if the load allows, it is no problem to hang the bomb. For example, for a 90-class oil engine, the maximum load is about.

3.5 kilograms. It depends on the size of the model.

Q: What can a remote-controlled helicopter be used for?

A: In addition to simple recreational flights, we are currently doing wedding performances, rescue, fire fighting, forest patrol, national security reconnaissance, aerial stringing, military drones, airport bird repellent, aerial photography and so on.

Q: How long can a remote-controlled helicopter fly at a time?

A: A tank of oil can fly for 20 to 30 minutes in hover, and it takes about 10 to 20 minutes to fly in action. Of course, it also depends on your fuel quality. If you need to fly for a long time, it is ok to add a fuel tank. Electric aircraft generally takes about 10 minutes.

Q: Why isn't the main landing gear of the remote-controlled helicopter made of metal?

Answer: If the main landing gear, the starting landing gear and the tail bevel gear engaged with it are all metal, then let's imagine that if the blades are not properly adjusted or vibrate or deform, the consequences will be quite serious, which is roughly equal to "Is the metal helicopter resistant to falling?" So I won't explain much, but the all-metal helicopter sounds good, and its main landing gear is not metal.

Q: When the plane starts, will the main rotor turn, will it hurt your hand and how to turn it off?

A: Our plane has been checked before leaving the factory. It is no problem to start according to the normal starting steps, because the plane starts at a low speed. Don't forget, as a remote-controlled helicopter of precision aircraft, the clutch is also essential. After starting, the plane is at idle speed. After we push the take-off lever, the engine is at high speed, and then the main rotor will turn. When the plane lands, it will return to the idle speed. There is a switch on the left side of the throttle, which will turn off.

Q: Can I fly out of the remote control range?

A: It's too far to fly. If your remote control is out of power, that's no problem, because some remote controls are equipped with out-of-control protection switches, that is, when your helicopter can't receive your remote control signal, the plane can keep the last action before losing control, or automatically return to an appropriate pitch and speed to make the helicopter land at a low speed; It's nonsense to say that the helicopter can fly back by itself. The store wants to fly within a controllable visual range.

Q: Which can fly better, an electric helicopter or a fuel helicopter?

A: Many beginners think that the cheapest oil-powered helicopter is close to 5,000 yuan. Why don't you buy an electric helicopter with a price of 1 0,000 yuan and practice first? Actually this is a very serious misunderstanding. Directly speaking, electric helicopters are more difficult to control and have lower power than oil-powered helicopters. Therefore, its counter torque is irregular, that is, the tail keeps turning, which is difficult for experts to control, let alone novices. At present, all the electric helicopters on the market are vacant for more than 15 minutes, but I can say responsibly that as long as you fly twice, you will understand that this is all bragging. It is good to fly for 8- 15 minutes with full charge, because the battery consumption is not as good as once, and it can only fly indoors. 3D flight consumes more batteries and the flight time will be shortened. However, fuel power is strong.

Q: How loud is the oil-powered helicopter when flying?

Answer: it's similar to a motorcycle, and the sound is not small. If you are flying, you will hear the wonderful sound of the main rotor interacting with the air. If you prefer a lower voice, she is really not as powerful as an electric helicopter, and can make a squeak like a mouse.

Q: What is the load of the remote-controlled helicopter?

A: Take Yatuo series helicopters as an example. Usually a 30-class helicopter can be carried.

1.5 kg, the 90-class helicopter can be adjusted to about 3.5 kg.

Q: Since it is a fuel-powered helicopter, why do you still use batteries?

A: The battery used in the airplane is also called the receiver battery, which is used to receive the signals sent by the remote controller and provide power for electronic equipment such as the movement of the airplane steering gear.

Q: How long does it take to charge the receiver battery once?

Answer: the original 1600 mAh battery pack can be used continuously for about 4-5 hours after being fully charged, and other single scattered batteries are similar, but never use a battery with one yuan and four batteries. If you want to fly for a while, you can join a group. Then again, you usually take a rest after flying for half an hour, and flying for five hours in a row is enough to lift your neck.

Q: How many adults can play? Which groups are suitable for?

A: It is impossible to buy a professional airplane model for children. There are toy-class planes for sale in the store, so you can consult them at any time. Many people like models, and they are a little embarrassed when they come here to buy them. In fact, there is no need to buy it for children. Children don't understand these things at all. The average helicopter flying crowd in China is about 40 years old with upper-middle income, and the price of 3,000 yuan to 10,000 yuan per plane is beyond the reach of low-income people.

Q: What are the climatic requirements and can they resist wind?

A: You can't fly in rainy days; Because the helicopter is an electric or oil-powered engine, there is no need to worry about wind resistance. Engineering aircraft can fly stably in the environment of 7 winds. There are related videos available on China Model Online. The larger the aircraft of the same class, the stronger the wind resistance and stability, so it is safe to fly in windy weather except rainy days.

Q: About purchasing complete sets of machines.

A: The store thinks it is ok for beginners to buy a 450-level kit, that is, all the items needed for airplane flight are ready, and players can fly directly after assembly and adjustment, but there is no kit in this store now; Some merchants constantly recommend customers to DIY and buy them themselves. In fact, for beginners, they only know that an airplane has a fuselage, an engine, a remote control and a gyro. When they buy it, the merchant tells you that you also need a spark plug, a starter, a starting lever, an igniter, a steering gear, and so on. It's endless, and it's always assembled after buying it, and it costs 200 yuan, which is very expensive. Therefore, I personally think that it is also beneficial for beginners to buy a set of machines with better configuration.

Q: What should I do if some parts are damaged after the plane explodes?

A: It can be said that any spare parts on the empty plane can be bought on Taobao because of the plane crash, but many players often say that there are many people playing in Alto, so it is easy to buy some parts. That makes sense. The store believes that no matter what brand of empty aircraft, there is no problem of not buying spare parts. We can only provide Fengshen machines and their parts in our shop.

Q: Why does the helicopter deviate to the left or other places when taking off, instead of taking off in a straight line?

A: Because of the gyro effect and downwash airflow of the main propeller, it is normal for the helicopter to lean to the left when taking off! You need to hit some aileron levers (right-hand horizontal levers) slightly to the right, instead of fine-tuning the aileron. After hovering stably, observe the left-right movement of the body and then adjust the aileron fine-tuning. If it deviates in other directions, it can be corrected by fine adjustment when it is on the ground.

Q: What is hovering and why do you practice hovering?

A: Hovering is a unique flight mode of helicopters, and it is also the charm of helicopter flight! As the name implies, helicopters almost stay at a certain height in the air, so that they can accomplish tasks that ordinary fixed-wing aircraft can't! For beginners, it is necessary to start from the practice of hovering flight, because the take-off and landing of helicopters and the beginning and end of other flight actions need to enter the hovering flight state first. So hovering has become the basic practice subject of helicopter flight!

The above is the basic knowledge I have compiled for you. I hope it will help you.
