WHat are they and who uses them? Some call them drones, some apply the label “quadcopters” ,though they can have any number of rotors or even be planes— ALSO called them “unmanned aerial systems” (UAS). I prefer to call them “unmanned aerial vehicles” (UAVs).
UAVs are and aren't new. Starting somewhere around 2013, a new trend emerged in the tech toy and aerial imaging market an explosion in popularity of compact multi-rotor RC aircraft, perhaps most notably the DJI Phantom 3 (or similar), a compact quadcopter capable of flying a GoPro either statically mounted or stabilized with a 2-axis gimbal, equipping them with cameras for FPV since cameras got small and video transmitters got cheap. Such technology can have many applications as a hobbiest and as a professional.
Why not to built our own at cheaper rates..:)
So lets get to understanding the drones("quadcopter" in my case) and then i will tell you how to make your own drone including each and every step i used to built my first drone.

Step 1: Know your quadcopter-How they Work
UVAs break into seven key components:
- Main Controller (MC) or Flight Controller
The heart of the flight-control system, this can be thought of as the “brains” of the UAV. It is an embedded computer that has custom software for controlling the aircraft, sometimes user-reprogrammable. In some designs the MC is a separate module with connection ports. On others, especially consumer products, there may be a single PCB (circuit board) that includes the MC, gyros/sensors, ESCs, and other core flight electronics. You can reffer to photos of MC i used in my drone.
>>I used KK2.1.5 Version of flight control board. They are pretty compact and built in gyros.
- Gyros/Sensors
For autonomy to work, the MC needs to track how the aircraft is flying. To accomplish this, some form of sensor array is provided. Generally, it will include accelerometers, IMUs (inertial measurement units), and gyros, and may also work in conjunction with positional data from an optical flow system or GPS/compass. Basically, these sensors tell the UAV how fast its acceleration is changing, in what direction, and whether it is right-side up. Those familiar with motorized gimbal camera stabilizers may recognize the same sensor technology being employed here as in gimbals.
- Electronic Speed Controllers (ESCs)
Each motor has an ESC . In its most basic form, an ESC regulates power going to the motor with which it is paired. More sophisticated systems can also relay data back to the MC, such as vitals about how the motors are performing. With six or more rotors, active feedback makes it possible to keep flying (enough to land safety) if one motor fails.
- Receiver
This receiver is for the radio control system. It pairs (“binds”) with the controller the pilot or operator holds, which logically, if confusingly, is known as the “transmitter.” Modern receivers typically operate in the 2.4GHz range (like other license-free radio systems such as Wi-Fi) and have four or more channels, extra channels enabling custom functionality to be relayed via the control signal, in addition to basic piloting inputs. In the hobby world, these extra channels might be used for anything from retracting/extending landing gear to firing off a smoke generator. In aerial imaging applications, the extra channels can sometimes be dedicated to gimbal or camera control.
- Motors
In most cases, these are brushless electric motors. The motors are usually paired, each pair a set containing one clockwise (CW) motor partnered with one counterclockwise (CCW) rotating motor, though they may be sold individually. It is important when replacing them or building your own system to use the correct rotational direction in the correct position. This can get confusing, as the propellers are often designated CW or CCW based on which way they screw on, not which way they rotate—which is probably the opposite direction!
- Propellers
Light UAVs use plastic propellers, which resist breaking on impact because they are flexible, and they are safer. Heaver models use carbon fiber or other more rigid materials (planes frequently use wood or nylon/glass). Carbon fiber propellers are dangerous, even deadly, and should be used only by experience pilots and well away from people. Unless extreme performance is a concern, the benefits of carbon fiber over plastic are marginal on multi-rotors.
- Transmitter
This is the radio controller. UAVs equipped with receivers, can work with a range of transmitters. This allows the user to select the best fit, depending on what features they are looking for and what their budget might be. Systems that include a transmitter (as well as other basic accessories required for flying) are dubbed “ready-to-fly,” and are the simplest to jumpstart the beginner. When investing in a transmitter, generally, compatibility can be determined by referring to the specs for the receiver. It will need to support the same protocol as the receiver and support at least as many channels as the receiver requires.
So, for example, 4-channel receiver will work happily with a 6-channel transmitter.

So i think its enough to understand our drone with quite brief introduction and now its time to move to our DIY section..:)
