A quadcopter or quad-rotor helicopter is a kind of helicopter having four rotating rotors. It was developed in the 1950s, soon after the development of the popular and much more advanced single-rotor helicopter. The first of these four rotor machines was the Blackbird, which was designed by NASA. In its first flight, it reached speeds of eighty miles per hour. Since then, many improvements have been made, and the original model can be seen in many model helicopters.
A quatrefoil quadcopter has a distinctive shape, resembling that of an upside down triangle. This design was later used in helicopter design. The controls of a quadcopter are separated into two panels, with each having an independent control set. The rotor blades and main rotor of the aircraft form the four rotors of the quadcopter. There are different kinds of engines that propel the craft; some use counter-rotating fan engines while others have inlet propellers.
Flight simulation software enables the user to create a virtual flying environment, complete with various kinds of aircraft, terrain and natural lighting. Realistic images and sounds, coupled with the sound of wind and engine sounds, as well as the aircraft movements can all be easily controlled using a computer. A single player mode allows a single player to control the aircraft and perform basic flight maneuvers, while a multiplayer mode can put up to four players on the field at the same time, battling it out for the best possible position. In the single player game, a player can often control multiple objects on the screen at the same time, like a jet or an airplane.
Although there are a number of models available for a Quadcopter, there are basically three kinds: the primary flight controller (PFC), secondary flight controllers (SFC) and a user-programmable chip (UPC). Each has its own independent model that can be upgraded, or programmed to run specific operations. Typically, these three models work in conjunction with each other. The PFC is the most flexible and is capable of running just about any kind of program that can be programmed into it. The SFC is fairly simple to program; however, it doesn’t have the same level of flexibility as the PFC.
The hobby of remote controlled helicopter or quadcopter flight is fast becoming a very popular recreational activity. For one, it is very affordable, and it does not require advanced technical skills. Moreover, many people can purchase the tools that they need for these hobbies online. These are perfect for those who would want to engage in recreational activities, without having to spend a great deal of money.
Each of the three major models in the range of quads have their own distinct characteristics, and all are capable of providing the right level of performance, depending on the type of application. For example, some of the quadcopters, like the radio control model, can be equipped with a variety of thrust vector controls. By configuring the rotor’s angle of attack, you can increase or decrease its thrust vector. This allows the motor to more precisely respond to any changes in direction. Likewise, increasing or decreasing the tilt of the wing will also alter the amount of thrust generated by the motor.
As the hobby of remote controlled helicopters has grown in recent years, several companies dedicated themselves to the development of different types of these recreational drones. One such company is ARF (Aerial Robotics Ltd.) which has a range of drones that are used for both commercial and recreational uses. Some of the quadcopter models that ARF has developed is the Shadow, Predator, Fireline, Stratos, Neuron, Dragon, Strato, Strata, Aerobat, Dragonfly, Stratosphere and Storm.
If you are looking for the most compact, easier to fly and the safest RC model available currently, you should look at the the bothezat helicopter. The de bothezat helicopter is equipped with a fixed, stable and powerful 2-bladed propeller that makes it easy to control during flight. Although this type of quadcopter is not as fast as a quadrocopter or a helicopter, it is surprisingly stable and quite stable even when it is at flight speeds of around twenty to thirty miles per hour, and is ideal for beginners and hobbyists who prefer a slower, less elaborate flight mode.
