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.
You also need to remember that a quadcopter has a front side and a back side. If the quadcopter is facing you the above-mentioned controls are switched. If previously pushing the right stick to the left made the machine roll to the right now it will make the machine roll to the left. All other controls are also adjusted accordingly. A transmitter also known as the remote controller comes with a number of parts buttons antenna and handle. There are two sticks: right and left. The right one controls roll and pitch and the left one controls yaw and throttle. Recall that throttle adjusts the altitude and yaw allows you to rotate it in either direction. Then there are trim buttons with each stick that are used to balance out the controls. You will need to fly your copter by pushing the throttle stick upwards and then see if it tilts automatically or flies itself to some direction without you even pushing the other controls. When this happens you will need to use the trim buttons on your transmitter to adjust the controls.
Bind-and-Fly on the other hand requires you to first bind the machine with its transmitter before taking it off ground. Such a machine is not meant for hobbyists as it requires a little assembly which only experts can handle. Similarly ARF or Almost-Ready-to-Fly aircraft require some sort of assembly before they could be used. These machines come with an instructions manual so that anyone could assemble it easily and quickly. They are perfect for expert pilots who already have the radio equipment (the transmitter and the receiver) and are only looking for other parts to complete the structure of their vehicles. All these UAVs are available off-the-shelf in the price range of $50 to $3000 and even more depending on their specifications model and overall design. Most quadcopters are very robust and durable and therefore they last for a long time if handled properly. Although these UAVs are considered friendly they do pose threat to public safety as they can mistakenly fly over private property and no-fly zones or collide with another aircraft damage something or crash land somewhere unknown. It is therefore advisable to follow the precautionary measures while flying these seemingly harmless quadcopters for the sake of fun in order to ensure safety.
There are some safety precautions to protect yourself as well as the machine from damaging itself and crash landing and also other people to get hurt. Remember to pull down the throttle to zero if you see your quadcopter going out of control and about to crash or collide with something. Always stay away from spinning propellers or do not handle a quadcopter when the propellers are rotating. This happens when youre trying to teach someone else to fly and then try to pick it up. When the transmitter is in someone elses hands and it is on the propellers can start spinning anytime so be very careful! Not everybody can fly a quadcopter with confidence because of a number of different controls its sophisticated design and intricate machinery. Even taking it off the ground and keeping it in the air without damaging objects that come in between is an art to master. Beginners especially find it really hard to fly a quadcopter without experiencing crash landing. Follow the above-mentioned guide if you are trying to polish your piloting skills or wish to master this art to enjoy the activity to its fullest.
