Remote control helicopter with USB charging cable

Remote control helicopter:
A remote control helicopter is a helicopter that can control the flight at a long distance. It can be divided into toys, model airplanes, civilian, military, etc. Now the most common is the model airplane remote control helicopter model. The remote control helicopter is divided into two types: electric and oil-powered. The biggest difference from a real helicopter is that it has an additional aileron to better control the direction of the rotor.
The actions of remote control helicopters, such as take-off, flight, and landing, are mainly completed by the rotors. When the main rotor blades rotate, an updraft relative to the air is generated, which naturally forms an upward force. The rotation speed of the rotor and the angle change of each blade are used to cause the aircraft to complete various flight actions such as take-off, ascent, and landing. The forward flight of the remote control helicopter is caused by the change of the angle of each blade in different positions according to a fixed law. The pulling force generated by the rotor tilts forward with respect to the rotating shaft, pulling the remote control helicopter forward. The same goes for making the remote control helicopter fly to the left or right.

How to choose a non-military remote control helicopter:
1. Model size selection.
Remote control helicopters are divided into different sizes. Many people who buy toy airplanes blindly pursue the bigger the better. In fact, the bigger the better, the fit is the most important thing. Especially for children, safety should be the first priority.
2. Remote control channel selection
For beginners, it is recommended to buy an electric three-channel or four-channel remote control helicopter. The more channels of the remote control helicopter, the more functions, and the more difficult the control will be.
3. Quality performance selection
When buying a remote control helicopter, you should pay attention to the quality of the aircraft. Although the appearance of different quality aircraft is the same, the performance is very different, and the price is also several times different.
4. Description of flight time, flight altitude, and fall resistance.
Regardless of whether it is an electric or fuel remote control aircraft, the continuous flight time in the air is relatively short. Generally, it can only fly continuously for about 6 to 15 minutes. This is due to the limitation of battery capacity and fuel volume, which is a common problem of all remote control aircraft, so do not Believe in the nonsense that some bad businesses can fly continuously for 30 minutes or even an hour, so as not to be deceived.
The flying height of a remote control helicopter has a lot to do with the size of the aircraft. Generally, the remote control distance of a small remote control aircraft is about 10 meters, and the flying height of a medium-sized or above can exceed 30 meters. Some people attach great importance to the flight altitude and remote control distance when buying, but in actual control, it is not recommended to fly too high, because it is easy to be affected by high air flow and cause loss of control. The higher and the farther the flight, the more difficult to control, and the probability of damage The bigger it is, it is not desirable to blindly pursue such data.
Some people have a misunderstanding about the anti-drop ability of remote control helicopters. Drop resistance does not mean that it is not broken. No matter how anti-drop things can not withstand high-altitude drops and strong impacts, especially for electronic components and plastic parts, any impact is possible. It will cause damage, so don’t trust the seller’s propaganda that it is not broken.
