Remote control model is a kind of entertainment, mainly divided into two parts, the remote control and model. Player mainly through remote control from electromagnetic wave (sometimes for infrared, but quite rare), driving or flying control model.
If you research remote control model deeply, it is a deep and complex world. Assembly, maintenance, handmade and handling of all kinds of remote control are very complicated. Some remote control model is children's toys, of course not be so complicated to operate. But the real professional players playing remote control model, all aspects are quite profound. For beginners, I'd like to give some suggestion.

| RC Helicopter |
For thr first time, the structure of the coaxial sculls is the best choice to the rc helicopter, the stability of this structure is the best, the speed is slow, the trainer is a helicopter! Also you can choose the traditional small level model of the main rotor + tail rotor structure, speed faster, airspace, but as far as possible, choosing the stability helicopter.
How much empty flight time (time) is mainly determined by the power system. Such as the motor power of the electric helicopter using size and carry the battery voltage and capacity, engine oil displacement of the helicopter and carry fuel volume. General electric or oil on a single charge or the blank time after refueling in 10 to 20 minutes or so. One is energy weight limit, the other is also considered to avoid the pilot lots of concentration for a long time transition fatigue caused by the manipulation of the error.
Due to the higher the height, the lower the air density, so the helicopter flight level are generally much lower than that of fixed wing aircraft, even so have distance is much larger than our visual control and remote control distance, so it can be for the aircraft's flight altitude and flight distance is the distance from the security of the remote control equipment remote control and visual range. Form special smaller aircraft usually flying height can reach more than 20 meters (about 5 to 6 floors).
The plane hard to control, there are two big reasons:
1. The stability of the helicopter can't be compared with the fixed wing aircraft. Besides the structure of the coaxial sculls again helicopter, there is no a helicopter can not control condition for a long time and stable floating in the sky (usually within 10 to 20 seconds off balance and fell to the ground), so you have to keep a spirit highly centralized control! 2. Due to the beginners in the first place has not been formed in the brain to control the direction of a reflex, so under the plane in a flight attitude, often through the transmitter to the plane error motion commands, and even the brain a blank, and the plane can't give enough time to correct the pilot, and fell to the ground. As long as the correct constantly practice can be easily manipulated. In the early also can be finished with the help of a computer simulator practice.

pitch
Pitch refers to the helicopter rotor or fixed wing of the propeller rotates 360 degrees, up or walk forward distance (in theory). Is just like a screw, screw you after a circle, can the length of screw in. The greater the pitch forward distance, whereas the smaller! However it is difficult to measure the size of the pitch, so general fixed wing aircraft using the same pitch labeled on the propeller of the diameter and the size of the pitch (mostly in the unit in inches), and in order to facilitate the appropriate engine systems. The vast majority of fixed pitch of helicopter blade is generally designed for a certain level of customization, so only indicate the diameter. Variable pitch helicopter can be very easily by measuring the Angle of attack of the blade Angle (wind) size to reflect the size of the pitch, and change.
hover
Hovering helicopter is peculiar to a way of flight is also the charm of helicopter flight! Just as its name implies is almost still stay in the air of a helicopter in height, which can accomplish common fixed wing aircraft was unable to complete the task! For beginner friends must begin from hovering flight of practice, because of the helicopter takeoff, landing, and other action is the beginning and end of the flight need to first enter the hovering flight status. So the hover became the base of helicopter flight practice subject!
paddle
Refers to two or more than paddle blade when rotating, are not at the same rotating plane held high! Blade tip like with open mouth of the scissors. Paddle is due to two or more different cause of blade pitch (lift). As long as all the tip of it with a different mark and with one of them as a benchmark, then observe the other oar the rotation is located in the top or bottom of the benchmark blade, can the other oar pitch (Angle of attack) are fine-tuned to watch again, such as observation held high two rotary surface which is eliminate the OARS. Double-screw can cause strong vibration, is must be eliminated!
gyroscope
Gyroscope is used to balance the direction of the helicopter, like fixed wing of the rudder. It can automatically control the helicopter in the transmitter was given direction instruction, keeping the original direction! Because it is a tiny devices with high sensitive sensor and highly automated, so its price is relatively high.
The spin
Spin is the body rotate 360 degrees centered on the propeller shaft. If there is a spin, so there are two possible. One, high-speed rotating to the left or right, the rudder no role, is the reverse, gyroscope swappable gyroscope reverse switch on the body. If not reverse switch, can be done by reverse installation fixed gyroscope; Two, head to the left (main blade clockwise models) slower spin.
Electronic governor
Electric helicopter power is provided by all kinds of motor, the power output size is determined by the rotation speed of the motor, and the speed of the motor is controlled by the electronic governor. RC model control steps are given as follows: the discretion of the transmitter throttle position through radio signals by plane receiver to receive after decoding, transmitted to a in the gas channel receiver on the socket electronic governor 3 core signal input, governor according to signal to determine the speed at the other end that how much power to the motor of electric supply distribution, to have the function of adjusting speed of the motor. We can put the governor simple as an adjustable resistor (actually more complicated).
I hope this help the novice to quick mastery skills to play model planes and more know the model helicopter,play it better.
