Drones

  Frame : There are two possibilities when it comes to a frame for your drone . You can make it yourself or buy it in an online store, and for a wide choice of high-quality frames, we suggest checking out our article about the best drone frames. If you decide to build it yourself, the project is not that difficult, but you’ll need some engineering knowledge and knowledge of the materials you are going to use. For instance, you can use metal (something light), plastic, or even wood slats. If you opt for a wooden frame, you’ll need a wood board that is about 2.5 cm thick.   Motors : For an ordinary quad, you will need 4 motors in total, but an octocopter requires eight motors to fly. The recommendation is to use brushless motors – they are lighter on the battery and, unless you are an engineer who completely understands how a motor works, these pieces should be bought from a store.   ESCs or electronic speed control: T hese are also essential pieces of your drone a...

 A quadcopter is also called a quadrotor helicopter or quadrotor. The quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft because their life is generated by a set of the rotor. Quadcopters generally use two pairs of identical fixed pitched propellers; two clockwise (CW) and two counterclockwise (CCW). These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor it is possible to specifically generate a desired total thrust; locate for the center of thrust both laterally and longitudinally, and to create a desired total torque, or turning force. Fig.1 Quadcopter Drone   Quadcopters differ from conventional helicopters, which use rotors that can vary the pitch of their blades dynamically as they move around the rotor hub. In the early days of flight, quadcopters (then referred to either as 'quad rotors' or simply as 'helicopters') were seen as possible solutions to some of the persistent problem...
