A quadcopter or quadrocopter is a form of helicopter with two rotors working in tandem. The term “quad” refers to the four rotating propellers. These machines are used for recreation, such as flying kites, remote control airplanes and even paragliding. The original design was made to be used by the armed forces. They have now been adopted by hobbyists as an easy to control, versatile, and affordable way to enjoy the sport.
There are several forms of this type of helicopter, including a fixed wing one, which has no tail rotor. There is also a mini-quad which has three rotors, and a propane powered mini-quad. There are also two-seat and three-seat versions. Each has a different variation on the basic design with the exception of the pitch and thrust capabilities.
This form of aircraft differs from a traditional helicopter in that it can go up to thirty miles per hour, which makes it ideal for sports piloting or other situations where high speeds are needed. It has much more power than its lighter cousin, the glider, but because it has four rotors it needs more skill to operate. Because it uses so much more power, a pilot must be experienced in other forms of aviation in addition to flying a mini-quad. The increased difficulty level is due to the extra complexity of the flight system.
As mentioned above, these helicopters are very popular with the armed forces. It is their main choice for surveillance operations. They can be armed with a machine gun or a laser, or other weapons that enable it to penetrate many targets that are many miles away. Due to the increased stealth and maneuverability, these types of helicopters are capable of remaining hidden in thick foliage, or being carried by a single passenger, whereas gliders cannot do this.
Another popular choice is the remote control helicopter, also known as RC helicopters. In this type of aircraft, the pilot uses a remote control transmitter on a computer to operate the blades, which are charged by a battery. The remote control then transfers this energy to propellers on the back of the aircraft. A remote controlled helicopter can fly as far as thirty miles per hour and, with the use of rechargeable batteries, can stay aloft up to forty-five miles.
The quadrotor, or quad-robot, is perhaps the most popular choice for a small-scale remote controlled vehicle, or RACV, as it is often called. This type of RC vehicle features four rotating rotors, each of which is servospeakers, which allow it to move its central fan at high speeds, much like a fan. Because each rotator is servo-stepped, it is capable of greater thrust in a smaller space. The RC drone is able to move at speeds of over eight miles per hour; this is much faster than the electric-powered RC toy, but can be difficult to fly, as its fan is not powerful enough to achieve flight.
The final option for RC toys is the helicopter, which is the fastest, yet has the least maneuverability. The fixed wing RC helicopter is the most stable of all the options and is often used for more advanced pilots who need stable and consistent flight times without the danger of a mid-air collision. The fixed wing lacks the agility of the other types of RC vehicles. It also has the least amount of power and typically requires a lot of flight time to achieve desired speeds. As a result, many hobbyists prefer the reliability of the fixed wing, while still allowing them to have some degree of maneuverability.
The electric RC toy, or RC airplane, is the most easily used by beginners because it is capable of both high speeds and longer flight times. The electric RC models are the most popular because they come with batteries that are easy to replace, and there is no need to maintain the motors or the rotors over time. The greatest benefit to these electric models is the small size of the motor and controller system. These are much smaller than the large and expensive motors and controllers used in helicopters and airplanes, and therefore can be stored easily and transported easily. Regardless of the type of RC model that you choose to fly, it is important to choose one that meets your skill level, has good flight characteristics, and is within your price range.
