Here is a basic list of the components you’ll need in order to build yourself a drone:
The 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 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 which 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. You can also get more familiar with them by reading our article about drone motors.

ESCs or electronic speed controls: these are also essential pieces of your drone as they are in charge of delivering power to the motors. Again, their number depends on the number of arms your drone is going to have.

Propellers: When looking for the propellers, you must find the ones that match the frame of your drone. Pay attention to materials – you won’t find wooden propellers, but you must make sure the ones you choose are a good fit.

Connectors: You will need 3.5 mm connectors to weld the motors and ESCs, as well as 4.5 mm connectors for the power distribution board.

The power distribution board – this board connects the electronic speed controls to the battery.

Batteries: When purchasing the batteries for your drone, you need to consider the capacity of a battery and its type. The most used batteries for this purpose are Li-Po batteries and their power differs. To have a much better insight on this topic, we strongly suggest checking out our article about drone batteries.

Battery monitor: This is not an elementary item, but the monitor is quite useful in warning you when the batteries are close to finishing. This way you don’t risk having the drone remain out of juice in the air, over a pond.

Mounting pad: It reduces the vibrations, and thus improves the flight. This one is very useful especially if you are trying to take pictures or videos with your DIY drone.

Controller- This device shares the power and commands the motors at the same time.

RC receiver: Of course that, if you have a transmitter (which is usually with you), you’ll also have a receiver mounted on the drone.

Micro SD Card

Camera: If you want to take aerial photos and record the surroundings while flying your drone, you will need a camera. The best cameras are those that can take the quality 4K videos, but everyone will find one according to its needs. For the high-quality photos and videos, you’ll also need a gimbal for the camera.

USB key: It is necessary to save the photos and videos.

These are the most important parts that every drone must contain in order to work and fly.
