A quadcopter or quadroopter is a kind of helicopter having four rotating propellers attached to its body. It was designed for indoor and low level flights, with agility and portability in mind. Some of them are extremely aerodynamic, allowing for inverted flight. They can be flown by one person, although larger ones can be flown by two persons.
The controls of a quadcopter are located on the top and bottom (throttle) panels. They are generally equipped with either a joystick or a control stick. Each of the four propellers can be controlled separately or simultaneously. The throttle itself can be set to take a variable amount of force into account, like while flying in a helicopter. This lets you adjust the amount of lift and airspeed required to fly a certain distance.
There is no electrical ignition system on a quadcopter, only the propellers and receiver. It can be powered either mechanically or electronically. In electronic stabilization, the pilot has the ability to fine-tune the quadcopter’s stability, turning it into a plane more similar to a helicopter. Electronic stabilization depends on the principle of servo-motor technology. A motor becomes capable of producing the needed force in response to inputs from the control stick, thereby imparting the right amount of lift or thrust.
A good example of an electronic stabilized quadcopter is the phantom 4, which has a pair of electric motors providing the lift and thrust. The transmitter of the phantom 4 can be controlled by a PC based computer, and the control of the propellers can be fine-tuned by a radio transmitter. The aircraft also has a very responsive control system, giving the user excellent control during high speeds. The only disadvantage to this type of quadcopter is that they run out of power when they are not in use, forcing the owners to recharge the batteries periodically.
A slightly different quadcopter, the phantom 5, uses a pair of propellers connected in tandem. Unlike the quadcopter of the previous model, this drone has four propellers, giving it a more realistic look and feel. They give a smoother and less jerky motion, but the major drawback is that these propellers also need to be connected to a separate receiver with a separate cable. This makes it difficult to use them in places where there is no terrestrial power source.
Some versions of this drone have the ability to move using only one propeller, called a left stick throttle. This quadcopter moves very realistically, with much more control than its sister models. The main drawback with this form of quadcopter is that it cannot be flown indoors. Also, it cannot use the left stick throttle for longer flights because it is quite difficult to get the throttle to stay in the right position.
In the Phantom 4, the controls are divided into separate channels. Each channel can be used for a particular function. For example, the FCS and ILS channels can be used to fly the quadcopter in autonomous mode, while the right stick is used for controlling the altitude, the left stick for controlling the rate of descent, and the forward and reverse gears. It can even control an aerial camera to provide a more complete view.
The newest addition to the Phantom family, the CH Pro, also incorporates a remote control with a separate gyroscope and laser rangefinder. It also offers two channels, one for the pitch/roll control, and one for the forward/backward movement. The new CH Pro does not offer a throttle, but instead uses a foot pedal for throttle control. It is much more complex than the previous models, however, and is only available for sale in Australia. It’s unclear when we will see helicopters like the CH Pro in the US.
