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.
Once your quadcopter is in the air you can fly it forwards backwards to the left and to the right. You need to hold the left stick (throttle) at all times to keep the machine airborne. The right stick will then be used to move it to any direction you want. The basic four directions are easy to learn; however once you have mastered these controls you should move on to experiment with yaw to rotate it in mid-air. These are the steps to make your first flight successful. With time and practice you will learn more advanced functions to fly your quadcopter in various patterns and thoroughly enjoy the experience. Some examples of various patterns include flying it in a square pattern or in a circle. You will need to hold down on one of the controls to make this happen repeatedly. Changing directions and rotating at the same time allows you to fly your copter continuously in the air. Its a good practice to fly up to an altitude of just a few feet in the beginning so that you dont damage it if you lose control.
This is a very good thing due to the geometry and weight distribution that Quadcopters have. Lower weight means more payload less fuel and/or longer range. Perhaps the weight savings of lube oil (2-types needed in normal current helicopter technology) on each of the four motors could also give weight space for electromagnetic bearings with a thrust bearing combination around the outer ring on the rotorblades to control vibration and free-wheel free of drag and easy start. If the motors happen to be electric even better in this case. If high speed gas turbines we save weight and add safety to a nearly maintenance free design. Some of the NASA tests have concluded 60000 hours with no damage or need to replace parts or bearings. For a rotorcraft this is nearly unheard of due to the harsh environment they fly and the fact that the motors are under so significant load all the time the aircraft is airborne.
Finally and this is a brilliant feature the Blade Nano QF BNF Quadcopter includes a "return to sender" button. At any time you can hit this button and your Nano will return straight back to you no matter where they are at that time. This alone is extremely useful for any time you have lost sight of your drone and need it back! Some buyers have complained about a weak RF signal sent from the remote control module saying that the signal isnt strong enough to support long-distance flights or those that climb higher and higher into the sky. However considered that this particular quadcopter has an advertised effective range of 200+ meters that really shouldnt be all that much of an issue. If you need to go higher and further than that you probably need a bigger more powerful drone. Secondly this specific remote-controlled quadracopter can be a bit of a challenge to fly particularly if you dont have any real experience backing you up with UAVs or drones.
