If you have decided to build your own Arduino Quadcopter, then you are at the right place.In this article, I will show you How I build my own Arduino Quadcopter using the Arduino Nano and Multiwii software.This will help you through all steps from fabrication to Arduino Flight controller making and programming it to build your own Arduino Quadcopter.In this post, I have discussed the Arduino Quadcopter Fabrication and then you will be guided to Arduino Flight Controller for Quadcopter in another post, If you directly want to go to the Arduino Flight controller Post Click here
Things You Need
- Quadcopter Frame
- 4 x Brushless Motors
- 4 x ESC’s
- Arduino Flight Controller(Read)
- Lipo Battery
- CW/CCW Propellers
- Power Distribution Cable
The Frame can be Build using Aluminium, Wood, Carbon Fibre or Acrylic, But the most commonly used is Aluminium and Carbon Fibre.I chose Aluminium for my Frame as it is easy to work with Aluminium rather than the Carbon Fibre.You can even buy a ready made frame if you dont want to build your own.
Now decide what shape of frame you want to Build an ‘X’ shaped Frame or an ‘H’ shaped Frame, I decided to Build an ‘H’ shaped Frame and use small steel ‘L’ Brackets for Joining the Frame Arms.
First I Cut four Aluminium C-Channel Bars of Length 2 x 35 cm, 2 x 33 cm then Drilled 3mm holes for M3 screws to attach steel Brackets.I did not want the Stock Silver Look of those Aluminium Bars, so I covered them with a Carbon Fibre Vinyl that I got from Amazon (Paper with Carbon Fibre texture Printed on it)
Then I joined Both the arm’s to the Middle Bars using Brackets with the Screws.I also Drilled three Holes for attaching my A2212/13T Motors at the end of both the arms.Two holes for attaching motors and one for the motor axis.
I attached a Rectangular Acrylic Plate at the Centre of the Frame which will be used to support the Lipo Battery and also add more strength to the Frame.
Make sure your frame is strong enough to take the vibrations from motors and propellers.
Now the Frame Was Ready for Electronics!
As the Frame is Ready I started putting on the electronics onto the Frame.
I first attached my Brushless Motors to the Arms of the Frame and made sure that the axis of the motor is rotating freely without any friction due to Frame.After putting on the motors I attached the ESC’s to each Motor and made sure that the spinning direction of the motor is same as in the image below.
Note: If the motor is spinning in the opposite directions then swap any two ESC wires out of the three
Then I used a Power Distribution cable to connect all Postive(Red) wires and all Negative(Black) wires of ESC’s to the Positive and Negative of Battery.

Now I Put my Arduino Flight Controller on to the Centre of the Frame using 3cm Standoff Spacers
To Build your Own Arduino Flight Controller Read this post
I attached all the ESC’s and my Receiver to the Arduino Flight Controller.I Plugged in my Lipo battery and tested the Quad with my transmitter without any Propellers On.
I Configured the Arduino Flight Controller Parameters in the Multiwii Config by connecting the Arduino Quadcopter to the computer Via USB cable.we can configure the Arduino quadcopter through any smartphone with this Application-EZgui
Attach your propellers and plug in the battery, Now the Arduino Quadcopter is Ready to Fly!
