UAV stands for Unmanned Aerial Vehicle and it covers all remotely controlled machines that are also known as quadcopters as well as aircraft used by the US air force. These machines are mainly used by military and police officers to carry out an operation where a manned aircraft seems impractical or too risky. Unmanned aircraft are not new; they have been in use since the World War I. However at that time the control was mechanical and the aircraft could only go as far as the fuel would allow. Later on devices that could be controlled with the help of radio or infra-red technology were developed. These devices became the predecessors of the modern quadcopter that employs integrated circuit or computer chips and can be programmed to fly for a definite time period in a definite direction fulfilling a definite purpose.
If you want to move forward the back two motors spin faster and the front two motors spin slower. This tilts the aircraft forward and vectors the thrust in that direction. If you want to roll then the same principle applies but on the lateral sides. If you want to yaw then you must understand angular torque. A spinning object will produce torque proportional to the speed with which it is spinning. That is why on traditional helicopters you see a main rotor and a tail rotor. If the main rotor is spinning counter clockwise the entire aircraft will want to spin clockwise to conserve angular momentum. That is why the tail rotor is necessary it produces the necessary thrust to counteract the forces of the angular momentum.
It should have an autopilot system intelligent orientation control and accessories such as a receiver and remote controller for easier navigation. There are extra minor features which are also important for many people such as live video streaming and the ability for one to control a GoPro quadcopter using a tablet or a smart phone. It should have a design that is highly integrated and attractive to catch the buyers eye. Software tuning and hardware mounting must have been done before delivery to spare the user any stress. It must have a setup that is fast and a control layout that is easy to maneuver. It is always relieving to receive a GoPro quadcopter that is pre-assembled after making an order. One only needs to charge its battery and put on the props.
When looking to buy a GoPro quadcopter there are several factors and questions that one must have in their mind. There is always the debate as to whether one should purchase a quadcopter thats ready for flying with GoPro or build their own. Many people who have taken up aerial viewing as a hobby will give advice on building one since its a much cheaper option and one has the surety that the performance will be exactly how they want it. Buying a GoPro quadcopter is beneficial since they work much faster and the parts are easily replaceable. This article though will focus on the buying option. Before making a purchase one must be sure what the purpose is whether its for flying or filming. Ready To Fly quadcopters abbreviated as RTF come having everything that is needed to fly from transmitters to batteries. They are more recommendable due to the less strain they give the user.
