If you have ever wondered what you need to get started in the RC hobby of multirotors this is the place for you. In this article I am going to outline all the basic components that are necessary to get started building your own quadcopter. First you are going to need a transmitter. The transmitter is the radio control that you use to communicate with your unmanned aerial vehicle (UAV). There are various types of transmitter that are categorized by brand frequency and number of channels. For a quadcopter you need at least a 4 channel transmitter but I would suggest getting a 6 channel transmitter that works on the 2.4GHz frequency.
Second you will need a flight control board. This is the brains of the quadcopter. It controls how the motors work. When choosing your flight control board it is important to remember that not all flight control boards are created equal. Some are extremely sophisticated and capable of numerous functions such as GPS mission planning return to home and loiter modes. Choose your flight control board based only on what you really need when you are just getting started you will not need all the bells and whistles. Third you will need the motors and electronics speed controllers (ESC). The ESCs interface with the flight control board which receives commands from the receiver. The flight control board calculates what the motors need to do to make the quadcopter do what the user is telling it to do then tells the ESCs which in turn tell motors how to spin.
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).
Additionally it has a size of 31 x 31 x 7.2cm and it offers you two colors options including green and white. Made of ABS and PS materials it has a super strong structure which ensures the safe flight. Exactly the prominent feature of JJRC H31 is the super anti-wrestling ability. Depending on the strong structure it will be intact even it falls from the high altitudes when it is out of control. Besides it has not been affected when impacted at high-speed flying. If you like you even can trample it on the ground. You do not have to worry about it because this completely damage will not bring it any effect. Very strong structure it has! Another feature I appreciate is the waterproof ability. This is very useful when you fly it near waters. If the RC drone immerses into the water and socks for a few minutes it is unnecessary for you to do any treatment. When it is full of water it even can complete 360 degrees rolling. Additionally JJRC H31 supports headless mode. Although this feature is normal for RC quads thanks to the special appearance design it is able to complete the pattern rotating action. And this has another benefit of flying in any direction you like.
