Course Description

PLEASE READ: In August 2023, I have updated the course with new lectures and a new flight controller. In the new lecture I show you how to upgrade your drone to use the popular MATEK F405TE flight controller. I have also added lectures about batteries and drone classifications. 

The MATEKSYS F405-TE is a perfect fit for our learning objectives. It's a minimalist yet powerful flight controller, making it an excellent device to explore.

Also, by transitioning to the MATEKSYS F405-TE, I can lower the overall cost of our drone without compromising its performance or capabilities. This will make our quadcopter design more accessible to hobbyists on a budget, which aligns with my mission to make drone technology more attainable and exciting for everyone.


Welcome to "Make an Open Source Drone", a course that will teach you how to build a quadcopter from scratch!

Playing with drones, and especially quadcopters, is fast becoming a very popular hobby. As a hobby, it combines state of the art open technology with large open spaces. It even gives me a great excuse to get out of my lab and get some sun!

While you can just go to a shop and purchase a drone that is ready to fly, by doing so you miss out on all the fun and knowledge that comes with building your own flying machine. I admit I have done that myself. Getting my ready-to-fly drone out of its box and flying it was fun, but only for a short period. 

Soon after the first excitement settled, I realised that I didn't know much more than before I opened the box. I was also unable to do anything more than what the drone was programmed to do, to begin with. 

That is why making your own open source drone is such a great way to have fun while learning. 

in this course, my co-instructor Aristofanis and I will help you understand drones and how to build them. You will learn about their mechanical and electronic components and how they interact. You will learn about the software that provides semi-autonomous flight capabilities to drones. 

Motors, flight controllers, Electronic Speed Controllers, batteries and chargers, receivers and transmitters, and so much more, will all make sense as you progress through this course and go through the process of assembling your drone. 

By the end of the course, apart from being able to assemble your drone, you will have the confidence to perform repairs and to extend its capabilities.

Along the way, you will learn about the principles of drones and many design and performance details for each of the components and software. With this knowledge, you will be able to go on and construct your own drones, configure and program them, all while having a great time doing so.

The course starts by explaining the basic principles of drones. 

You will learn about the types of multi-rotor drones, flight terminology, principles of drone flight, and we will introduce the basic drone components like propellers, motors, the flight controller and more.

Then, you will get into the actual construction of the drone. You will solder the Electronic Speed Controllers to the motors and assemble the drone arms.

You will then solder the ESCs and battery to the power distribution board, and start the assembly of the drone frame.

After that is the radio control subsystem. You will learn about the different types of signalling, connect the radio receiver to the flight controller, and connect the GPS module.

Next, you will learn about LiPo batteries and battery chargers, safety and maintenance. 

With a fully charged battery, you will continue with the firmware and software. You will learn about the MegaPirateNG firmware and how to upload it to your drone. 

You will learn how to bind your radio transmitter and receiver, and then how to calibrate your new quadcopter using the open source Mission Planner software.

As always, we save the best for last! At the end of the course, you will learn how to calibrate the Electronic Speed Controllers and attach the propellers.

And in the end, you will be able to take your drone to a field and launch it, starting to build-up your pilot skills!

As with all Tech Explorations courses, we are here to help you in this exciting learning journey. As a student of this course, you will have access to the Questions and Answers board and interact with the instructors. You can ask questions, and make comments or suggestions. 

Please continue by having a look at the list of parts that you will need in this course. You can find it as a document download in the next lecture

The course is very detailed and easy to follow. The instructor takes the time to clearly explain each process, including important dos and don’ts, which makes learning much more effective. It’s truly an amazing course and definitely worth buying. I do wish there was a bit more explanation about other transmitters like RadioMaster. However, since many of the terms are similar, I can explore that separately through additional research. It’s also possible that this is covered later in the course and I just haven’t reached that part yet. Overall, I highly recommend this course.

Alhammdulilah. I am very happy to take this course, because I got the knowledge that I was not expected. Actually Dr. peter you did a great work and your effort as to be recommended, I appreciate your effort. I have no ideal on quad-copter or drone generally but with this course am able to come up (design) with my quad-copter and not only that I can also impact the knowledge to another person with out look for any book. I we also appreciate Udemy for there support and hardworking for making a positive impact to the world through technology. Thanks you all.

As a 14-year-old beginner in drone building, this course really helped me understand the functions of all the drone’s parts, how everything is assembled, and, most importantly, how to fly it. Unlike other courses that are just made up of PowerPoints, this one actually had clear videos and showed the drone being assembled right in front of us. That made it way easier to follow along and way more engaging. Since the drone is quite powerful, its components—especially the flight controller and remote controller—aren’t cheap, and some parts can be difficult to find in certain regions. All things considered, the course was super beneficial, insightful, and fascinating. I would definitely recommend it to anyone who’s new to drone making!

I build a drone following this course 4 years ago. I like the detailed setup with the good quality video and easy to understand his voice. Very good hands-on course and good explanation of the needed theory to know at least the basic of what you have created. Not sure if lesson 80 with use Power Module is optimal, no response to questions in Q&A.

By Michael O'Neal on 4/11/2021

I'm very happy with the results and am now able to practice flying. I couldn't have done it without this course. The only suggestions that I would make would be to remove everything that is associated with the Crius FC. That caused a little confusion. Also, there were some difficulties in getting the transmitter to arm, due to a couple of error messages. So perhaps some time addressing those kind of issues would be a good thing.

By Jerome Attia on 10/29/2020

Good course but it is about five years late with the incredible changes happening in the drone's field. This drone is ugly, too heavy and the recommended radio is way too cheap ! Updated after having tried on modern controller card + small gps etc, I have been unable to reproduce de simplicity and efficiency of this drone, especially the return to home function and other GPS functions where I failed miserably. So thumbs up for the ugly drone!!

By Mark Pryor on 4/29/2019

The course was excellent except section 83.860. The initial setup wizard was basically skipped. I would have liked to have had explanations on setting up the other 8 parts in addition to the compass. Hence I would liked to rate it at 4.7, but 5 stars is closest. Now to start his next drone course.

By Art Juan on 1/10/2019

This course was exactly what I was looking for. Professor Dalmaris is patient and thorough. Everyone just starting out in the drone hobby should take this course. Great job! I look forward to taking the additional courses that I've already signed-up for. Especially those with Professor Dalmaris. Thank you.

By Beena Hemkar on 10/23/2018

In this course, the instructor Peter Dalmaris goes well in depth and demonstrates the step by step procedure by doing it in front of the camera! This really helps when you are building and following along. Unlike other drone courses, Peter also does a great job of providing an upgrade option, within this course, so you are not just building a basic drone, but also bringing it in compliance with what's currently available in the intermediate drone's range of controllers. He is really responsive and is very encouraging towards young minds who want to learn this technology!

By Ron Gaskin on 9/5/2018

This drone was a project that took time and patience. I ran into challenges along the way but learned from them all. The technology utilized in this drone is amazing. The accuracy of the GPS is scary. I am now the defacto electronic maker in my family (my bro went to Devry institute (USA)) :) thank you Peter.
