One of the most durable, while still most exciting remote controlled machine to operate is no wonder RC helicopter. It is a fact that for mastering the art of flying RC machines, you will need to dedicate lots of time and skill. Even though RC helicopter’s field is progressing quickly, but if you are new to all this RC Quadcopter Aircrafts hype, then this article might be the suit for you because it may help you understand the basics of operation of different RC helicopter models.
RC Helicopters, How do they operate?
Even though they might look simple, but the RC helicopters are very complex machines to work with. With hundreds of moving parts to operate from the power source, this design is made even more complex, all thanks to the radio transmitter and the radio receiver for receiving and sending the signals. Even though they may not seem as important, but the fact is that they are the solely responsible for transmission and reception of incoming as well as outgoing signals.
To define it further, transmitter can be regarded as a device used to send the commands to RC helicopter while its flying. While the receiver inside the RC helicopter receives the signal, it then sends it to the internal circuitry of the helicopter allowing it to perform the requested commands.
You must make sure that you have a fully charged transmitter and receiver when you take your RC helicopter out for a flight. If you are flying it, and any of them, either the transmitter, or receiver dies due to low power, then the ultimate result will be the complete crash from the air of the machine, resulting in sever losses to physical structure of the machine. That is why you should give proper attention to the battery status of the machinery.
How Do RC Helicopters Actually Fly?
Operating principles of ‘little’ RC helicopters and complete helicopters designed for military is almost same. Operation of a Best 3D RC Helicopter is based upon the two components i.e. the tail rotor and the primary main rotor.
Primary rotor, or main rotor, is the one which revolves on the top of the helicopter. For lifting up and during flight, the main power and push up force is offered by this rotor. Most helicopters employ rotors revolving with constant speed and lift is produced by the alteration of pitch and attack angles of the main blades. Amount of the lifting off power is proportional to the pitch of the rotor.
Twisting force is exerted upon the entire helicopter while the main rotor picks up its speed. This is where the tail rotor steps into the play. It helps in balancing the overall spinning force of the primary rotor by counteraction. This helps in keeping the helicopter erect while it starts taking off. Tail rotor acts the same way in helicopter as the rudders do in the marine ships, that is its always running opposite to the main rotors force. This helps in steering of the helicopter as well. For connecting main rotor to the tail rotor, belts or even torque rods are employed. For each motion of main rotor, tail rotor can mo move up to 6 times the spins.
It’s a common sight to see in newbies, that they keep looking at tail of the RC helicopters as flying it, and give no attention to nose of the helicopter. It’s a big mistake, because you must give attention to nose and completely disregard what the tail is doing. Because the nose is driving parameter on where the helicopter will led, not the tail. For gaining the complete control of the helicopter, you must focus on the nose of the helicopter.
