They appeal to all everybody and all ages too! Quadcopters are a huge amount of fun and they arent just for boys either! Girls also love being "pilots" and enjoying the thrill of commanding their drone either just around the skies or performing intricate stunts and manoeuvres. And these bad boys of the sky arent just for kids either. From as young as 7 years old right up to grandparents there is a drone or quadcopter that will suit. There is an absolutely HUGE range of quadcopters for sale that will cater to any budget and also please the most demanding of "pilots." From a small entry level quadcopter that can fit into the palm of your hand right up to an incredibly advanced... and expensive version that costs more than the average family car! Want four propellers? No problem? How about an eight propeller octocopter? Too easy! Want a protective circular cage around your drone or maybe perhaps even in the shape of a fighter jet? There are so many different options available to you! Just go down to your favorite RC store choose what you want and you are ready to go!
Deciding which specific motors to use was a hard decision. Knowing roughly what I needed was easy. If you look around you quickly learn that there are really only two sizes of quadcopters out there. There are medium-sized quadcopters that dont carry a payload and are designed for 3D flying. These use electric motors of about 45 grams (1.6 oz) each. I already knew mine was not going to be one of these. Unlike an airplane if you have a motor failure in a quadcopter you are dead. There are no inexpensive top quality motors so I decided to spend what I needed to spend to get the quality I wanted. I need to explain why a low Kv (motor voltage constant) was so important for the motors. A speed control (ESC) is not infinitely variable. When you move the throttle stick the ESC might not be able to exactly match the amount of movement requested. Having low Kv motors effectively makes these incremental steps smaller. When the software of the flight controller needs to maintain the quadcopter level having this finer control makes its job easier. You then will have a smoother flying quad which is best for shooting video.
The most obvious standout feature that this remote-controlled quadcopter offers is surely its incredibly compact size. A lot of the hobby drones out there are massive monstrosities that can be very slow and quite challenging to get up off the ground. And even more of a challenge to control in inclement weather-- but the same can not be said when youre discussing the Blade Nano QF BNF. Small enough to fly around in a single room in your house or office but sturdy enough to fly around outside in nearly any weather condition (insert obvious disclaimer about storms hurricanes and tornadoes of course) this is a quadcopter design that is set to revolutionize the industry.
Fourth you will need a battery to power all the electronics. Lithium Polymer (LiPo) batteries are the most popular batteries for the RC hobby. LiPo batteries are characterized by their number of cells (voltage) and capacity (mAh). Each LiPo cell has 3.7V so a 1S (1 cell) battery will be 3.7V a 2S battery will be 7.4V 3S 11.1 V and so forth. Capacity is rated in milliamp hours (mAh). The higher the number of mAh the longer the battery can power the quadcopter. Lastly you will need a frame to put all this onto. There are many commercially available quadcopter frames. Some are in the + configuration which means one of the arms acts as the "forward" orientation. Some are in the X configuration which means that "forward" is between two of the arms. There is also the H frame where forward is on the flat side of the H. H frame is great for FPV and aerial photography since the rotors are out of the way.
