You may have seen some pretty amazing flying vehicles these days. UAVs (unmanned aerial vehicles) are becoming more and more common. The hobby is also getting more and more easy to get into. But with the great range of models and brands you may wonder what is the best quadcopter to start out with. There are a several variations of the multirotor family. The most common is the quadcopter like the DJI Phantom. A quadcopter uses four motors and propellers to generate the thrust necessary to lift the aircraft. It can be more mechanically simple than a traditional helicopter that requires a tail rotor to counteract the angular torque produced by the main rotor and the main rotor does not require collective pitch and other mechanical complexities. With a quadcopter the pitch is fixed and the flight control is achieved by actively changing the motor RPM (revolutions per second).
So because it is so difficult to learn how to fly a quadcopter I will always recommend that a beginner buy a small quadcopter toy before dropping $450 on a DJI Phantom for example. There are a couple good little quadcopter toys out there but my favorite is the Syma X1 Quadcopter. It comes in a few different configurations you can get a space ship bumblebee or UFO. It comes with everything you need to fly for just about $30. That includes a 2.4 GHz transmitter so you can fly indoors and outdoors with a pretty good range. It also means that you can fly more than a couple of these guys around. It can also do flips in any direction at the touch of a button! One important thing to note is how to calibrate it. A lot of people think that their quadcopter is broken because after they plug in the battery and try to fly it it will always veer off in one direction. This is because when they plugged it in it wasnt on level ground when it calibrated the gyros. So what the flight controller thinks is level really isnt level. So what you have to do is plug in the battery then immediately place it on a flat surface so it can calibrate correctly. Then you are ready to go!
I knew that choosing the flight controller needed to come next. After all quadcopters replace mechanical parts with gyros. If you think about it it is really just like a computer game! Im a terrible helicopter pilot. I can barely control a coaxial beginners helicopter. Being able to use a flight controller was a big part of the appeal of a multirotor platform. The simpler flight controllers only have angular rate of turn sensors. These sensors are what we call gyros. They can sense when you are turning but that is all. A feature that I really wanted the flight controller to have was accelerometers. An accelerometer can tell in which direction is down by measuring the acceleration due to gravity. With this auto leveling feature I can let go of the control sticks when I get into trouble and it will bring it back to perfectly level attitude. This was very important to me!
Have you ever had a chance to fly a quadcopter? If not you have no idea just how exciting it is to fly these machines with precision accuracy using a remote controller. However once you do attempt to fly one you will encounter many problems in the beginning. This is because this type of an aerial machine is extremely sophisticated and it requires a good number of trial-and-error attempts to master the skill of handling it perfectly. Whether you have already tried your luck on flying one or youve yet to take your first one in air this article will help you learn the basics of flying and refine your skills so that you can tremendously enjoy this pastime.
