The construction process of a multicopter is quite harmless, but there are simply a couple of things you must be cautious with throughout the building and onwards.
Batteries
Foremost to be careful about is the energy source you are using. Almost all remote control multicopter guides recommend the lithium polymer energy cells by way of power resource. These produce a huge amount of electricity needed by brushless engines. Charging these batteries wrongly or short-circuiting them would cause explosions and combustion.
Propellers
Never utilize propellers on multicopters unless crucial. In many cases, you would need them simply in the last stage of building. Propellers on the run are similar to knives, and therefore, can bring about serious harm to property and people. In addition, always do your multicopter flying in an empty area with much space.
Basic building
To begin building the quad copter, you have to prepare all its needed parts. For beginners, keeping your initial model easy is highly recommended. Start with mounting your brushless engines, energy cells, besides other electric equipment easily. If you choose to create your frame, remember that it needs to be leveled and firm.
Brushless engines or motors possess three wirings that control the three stages of the motor. When linking the engine to its Electronic Speed Controller or ESC, it doesn’t actually count how you join the cables to allow it to spin. This device has three wire sets, namely the two thick current supply; the three dense motor cables; and, the three small controller wires.
For the multicopter to remain in flight, you will need an equal distribution of propeller clockwise, as well as counter-clockwise. This ensures that the multicopter would not turn around. A multicopter control board exists as an essential portion of the multicopter. It is the core that controls the motors independently, as well as correcting the balance.
You may use the Quadcopter control board V2.1 or a blackboard v5.5 as both has similar results, besides being identical. Be wary, however, as to where you order the blackboards. There are retailers on Ebay, but some are identified to vend faulty and improperly tested multicopter control boards.
Hence, it is highly suggested that you consider buying from multicopter manufacturers, official retailers on the developer website, or through http://www.larsleonhardt.com. Also, buy a USBASP programmer card for supplying the board with software outline needed.

You will likewise need to regulate your multicopter through a transmitter, such as a Spektrum Dx6i. This brand has six stations, where four actually enough to support the multicopter. The fifth station is, however, generally used for illumination. Moreover, when off-course, a satellite receiver is equally needed for projects aimed at optimal clarity.
Multicopter flying basics
For all time, there is an aeronautical direction founded on the framing of the control panel. This stays necessary since you would not know whatever may result of the navigation from the transmitter. The flying direction remains often described by LED lighting or foam ball. Thus, it could be known from the field.
