However, in the best RC helicopter, it is not always considered as the helicopter, which makes it very difficult to maintain orientation and maintain control. I have even heard that full-size helicopters say that a popular RC helicopter is more difficult to fly, although, in reality, it is unlikely to be so, staying aligned when the helicopter is extremely difficult to master.
The main rotor, the tail rotor, the swing plate assembly, the collective control, and the cyclic control.
The main Rotor
A gyroscope, either mechanical or piezoelectric, measures the difference in the rotational force between the helicopter and the tail rotor and adjusts the inclination of the tail rotor accordingly to keep the heli RC stable.
The tail rotor is typically mounted at a 90-degree angle to the main rotor and provides a lateral thrust that counteracts the rotational force applied by the main rotors to keep it straight.
The oscillating plate assembly fits the main rotor shaft below the heli head and consists of a rotating disk and a non-rotating disk.
The lower non-rotating disk is directly connected to the cyclic and collective controls that are controlled by servos under the command of the pilot transmitter inputs.
This non-rotating disk is connected by a bearing to the second rotating disk, which rotates with the rotor and is connected to the pitch horns of the main rotor blade.
How do RC helicopters fly?
How does an RC helicopter fly? Someone once said that it exceeds the air in submission, and in fact, it does so in some way.The main rotor, the tail rotor, the swing plate assembly, the collective control, and the cyclic control.
The main Rotor
- A conventional RC helicopter has its main rotor in the fuselage (body) consisting of 2 or more rotor blades that extend from a central rotor head or a central rotor assembly.
- The main rotor of an RC helicopter is the one that generates the lifting power that makes the RC helicopter fly. The rotors of an RC helicopter have the shape of an airplane wing, only they are thinner, narrower and both sides are symmetrical.
- As the rotor blades rotate through the air, they create buoyancy. The amount of lift generated is determined by the angle of inclination (and speed) of each rotor blade as it moves through the air. The angle of inclination is called the angle of attack when the rotors are moving.
The amount of thrust produced by the tail rotor is determined by its angle of attack.
Increasing the fixing angle (inclination) of the tail rotor blade will increase the thrust, which will push the helicopter in the same direction as the main rotor blades, while decreasing the inclination will decrease the amount of thrust, allowing the natural torque of the main rotors so that the helicopter rotates in the opposite direction to the main rotors.A gyroscope, either mechanical or piezoelectric, measures the difference in the rotational force between the helicopter and the tail rotor and adjusts the inclination of the tail rotor accordingly to keep the heli RC stable.
The tail rotor is typically mounted at a 90-degree angle to the main rotor and provides a lateral thrust that counteracts the rotational force applied by the main rotors to keep it straight.
The Swashplate set
The place of the swash in an RC helicopter (or full size) is used to translate the commands of the pilots in the movement of the main rotor blades and/or flybar.The oscillating plate assembly fits the main rotor shaft below the heli head and consists of a rotating disk and a non-rotating disk.
The lower non-rotating disk is directly connected to the cyclic and collective controls that are controlled by servos under the command of the pilot transmitter inputs.
This non-rotating disk is connected by a bearing to the second rotating disk, which rotates with the rotor and is connected to the pitch horns of the main rotor blade.
