Build Your Own Drone – DIY Drone Parts

Drones have been around for decades, but their popularity has risen in recent years as a result of advances in First Person View (FPV) technology, such as the GPS system, which has opened up a whole new world for outdoor enthusiasts. Building a drone from the ground up can be scary, and many individuals are hesitant to even bring up the subject. The best part is that it isn’t as difficult as it appears.

You’ve come to the right place if you want to learn how to build your first flying drone. Stay tuned as we go over all of the DIY drone parts you’ll need to create your own drone and complete a fantastic project!


Four motors are required to build a standard drone, but eight are required to build an octocopter. Brushless motors are recommended when purchasing these motors because they are light and consume less power. However, if you are familiar with motors and their general impact on power usage, you should be able to make an informed decision.

Because the drone is light, motors that are light in weight and on the battery reduce the time it takes to recharge and extend the range of the drone. Motors are one of the most important DIY drone parts since they give the necessary power to fly your drone.


Once you’ve decided on the number of motors your drone will have, selecting the frame or shell of your drone becomes rather simple. You have two options here: buy it from a store or make one at home. If you wish to build the frame yourself, you’ll require engineering knowledge. 

Light metal, plastic, and even wood are all options. Make sure the structure is sturdy and won’t collapse in mid-flight. Choose 2.5 cm thick wood boards for your frames.


Propellers When purchasing propellers, ensure the ones you choose are compatible with the frame of your drone. Make sure the material you’re using is capable of lifting your drone. You won’t find any made of wood, so make the greatest choice you can. Propellers are always identified by a four-digit number, such as 7534, 9876, or 5435. The first two numbers represent the propeller’s diameter in inches, so a 7524 propeller will have a diameter of 7.5 inches (19.05 cm).

The pitch is determined by the final two numbers, so the 7524 props will have a 2.4 inch (6.1 cm) pitch. The pitch, in essence, determines how forceful the props will be. A propeller with a higher pitch will move a lot of air downwards. They are utilised in low KV motors and spin slowly compared to low-pitched props. Lower-pitched motors spin quicker to compensate for the limited amount of air that is pushed down to aid lift-up.

Electronic Speed Regulators (ESCs)

These are essential equipment because they deliver and regulate the amount of power given to the motors. Brushless motors, on the other hand, do not require ESCs because they only require a simple DC power supply.

Brushless motors will require a voltage input of 3 volts out of phase. This may sound frightening, but once you connect the ESC, it will automatically generate the three out of phase voltage, which will cause the motor to spin. It’s crucial to double-check the input voltage range with the manufacturer or a retail representative.

An ESC has three outputs, which you’ll connect to the female bullet connectors on the motor with solder.

Board for distributing power

This is where you’ll connect all of your major electrical components. The ESCs and battery terminal linkages are the key components you’ll be soldering here. When you connect the batteries to the power distributor board, it will power everything connected to it, including your motors, which will be powered by the ESCs.


Lithium Polymer, or Li-Po batteries, are the most prevalent type of drone battery. Consider the battery’s capacity before making a purchase, as you don’t want to be buying a pair every now and again. The batteries are one of the most significant DIY drone parts since they offer the necessary power to fly.

Identifying Li-Po Cells

A battery, as you surely know, is a collection of several little cells or individual batteries connected together. When exhausted, a Li-Po cell has a maximum voltage of 4.2V and measures 3.7V. Because the volts add up when the Li-Po batteries are connected in series, you’ll get the maximum voltage. A 4S component Li-Po cell will receive a full charge of 44.2=16.8V.


You’ll need a certified charger because your Li-Po batteries are rechargeable. The charging process must be done in a regulated manner, as doing so risks the batteries exploding. There are numerous clever Li-Po chargers to pick from that can handle the heavy lifting for you by balancing the charge on their own.

Connectors You’ll need 4.5 mm connectors for the PDB (power distributor board) and 3.5 mm connectors to weld the ESCs and motors together while building your drone.

Controller of the aircraft

Because this is the brain of your unmanned aircraft, you must get it properly. It’s a hardware hub to which all other components, including the GPS system, ESCs, and RC inputs, will be connected. An accelerometer and a gyroscope are two components of a decent flight controller that work together to automatically balance your drone without the need for user assistance

A firmware controls the flight controllers. You may be able to make a few changes depending on which one you choose. There are two sorts of firmware: closed source (invisible to the public) and open source (accessible to the public) (you can see the codes and make a few changes suitable to you). If you want to use open source firmware like the PX4 or ArduPilot on your drone, be sure the board you’re buying supports it.

When selecting a Flight Controller, make sure to select one with the most processing power. It’s best to go with one that has an F3 or F4 processor. The F7 is still in its early stages of development and is not extensively utilised. The F1 chips, which have been around for a long time, are no longer supported and will be obsolete in the near future.

RC Controller

This gadget serves as a space between the user and the drone. Contains a receiver and a transmitter. The receiver is connected to the flight controller to receive a response signal. There are a variety of controls but the cheaper ones have limited channels. In a drone, the minimum number of channels should be 5 or 6.

Each drone automatically selects four channels, namely, throttle control, yaw, roll and pitch. Some additional channels are designed for unique and easy navigation such as changing the flight mode of your multi-rotor. The controller is one of the most important parts of the DIY Drone.

Battery Monitor

You shouldn’t have it but it’s good if you have it. It is very useful as it will warn you when the batteries run out. This way, you do not risk losing your drone in the air, much worse than the lake!

Input Pads

They are not as important as the help of a moisture vibrator that stabilizes the aircraft. This feature is important as it helps you to take clear pictures and videos.

VFP Camera

This is usually the eye / eyes of your drone. What we will see, you will also be able to see. When buying cameras, make sure they can see in all light conditions and there is no slowing down as this may cause a crash. Many cameras with mounts are easily installed on any frame. Choose a camera with CCD or CMOS. The difference is that CMOS is simpler and cheaper but reacts less when light conditions change. CCDs are different. The rapid camera response is important because drone aircraft often face dark areas followed by bright sunlight. Any delay or lack of visibility can eventually look like a crash.

Video horns

The best way to increase the width of your drone and capture HD videos is to equip them with video sticks and not really VTX (Video Transmitters). Any drone needs two horns, one to send and the other to receive video. There are a few factors to consider such as antenna type and product, connector type, polarization and durability. Check with the manufacturer to see which antennas and connection options fit best with your drone.

Recording Cameras

Here you can make a personal choice but definitely want to get HD video and quality photos – right? The only downside to the cameras is the extra weight, which increases the risk of crash and, worse, the drone loss. When buying a photo camera, consider the following: weight, mounting options, video quality, durability to avoid injury in the event of an accident and viewing area.

USB and Micro SD Ports

It is important to save videos and photos. Make sure you have a USB or SD card slot where you will automatically save your photos and videos.

Final Words – DIY Drone Parts 

Choosing the right parts for a DIY drone is your mix of both science and art. However, the most important thing that should come before this is both the performance and the ability of the drone to fly without risk. Assembling the parts requires great patience and perseverance.

In addition to the parts mentioned, you will need cable locks, AWG silicone cords, zip ties, servo lead cords and 3M command threads. You are free to add some additional features to make your drone look better and more advanced!
