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.
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!
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.
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.
