@@masoudmasoudi6534 thank you for the comment. The software utilizes some very hardware specific features (DMA channels) of the Teensy 4.0 to generate fast control signals. Not sure if similar functionality is available on esp or avr. The software is available on GitHub 🙂

It uses a back-to-back BLDC motor configuration. If you are interested you should take a look at my thesis 😁github.com/SolidGeek/SingleRotorUAV/blob/main/thesis.pdf

@@MrSolidGeek wow man, awesome ty so much for sharing this.

I am trying to do the same thing with one EDF motor. Can you please tell me if an EDF motor is good for this project, or should I use a propeller motor?

@@firazpeerjade It can definitely be done with an EDF, however, because it only rotates in one direction, the fins would have to counteract the rotational torque of the EDF (which could saturate the actuation). Another issue is the small radius of the EDF, making it difficult to get enough area on the fins I would assume.

@@MrSolidGeek ty so much for sharing your experience.

Thank you! The craft have four fins in the outlet, that controls the airflow. These can be actuated to produce both roll and pitch moment, but also yaw. To produce a yaw moment, all four fins rotate in the same direction, producing an opposite spinning torque.

@UCnrbeoZXn7-rluh-iHhzsCQ Yes, I understand the cancellation of rotation at constant engine speed, but in case of accelerating and decelerating, the rear fins must make corrections in real time, and that is what surprises me...;)

@@MrSolidGeek I don't know if you know the studies on coanda effect by Dr Bob Collins (www.researchgate.net/publication/264382893_COANDA_FLIGHT_CONTROLS). I think that the flight control system that has been developed could be applied to a drone that functions by the coanda effect.

@@guillermogonzalez5915 Yes it happens in real time. The yaw controllers output is basically added together with the control output of the roll and pitch, which is mapped to the fins. However, to minimize the torque at acceleration, I also use a counter-rotating motor setup (two rotors back-to-back). This greatly helps reducing the torque at acceleration, but does not eliminate it as the motors does not equally share the load.

Coaxial blade configuration or maybe anti-torque vector with the vanes below the EDF.

​@@Joe-zw9ep it is a single prop. He answered this above: "Thank you! The craft have four fins in the outlet, that controls the airflow. These can be actuated to produce both roll and pitch moment, but also yaw. To produce a yaw moment, all four fins rotate in the same direction, producing an opposite spinning torque."

You should be using the master branch, not the Firefly. That is an old development project. It is important that you have installed the library in the correct place for Arduino to find it. I will take a look if I can compile it later

I am not sure how to help you. I was using the nRF SDK which has some built in gfx functions. Sorry I cant be of much help

@@MrSolidGeek can i get your source code

I feel you

Thanks mate, that sounds very interesting! I was also looking into using gimbal EDF, however they seemed a little to complex for my project. Please keep me updated on your findings, it is very interesting! Also, where did you find my paper?

@@MrSolidGeek I absolutely will mate. I just burnt my ESC and edf motor right after i finally got my controller working, ordered new/better ones so I am just waiting for parts (torture really). I don’t remember exactly where I found your paper but somewhere on google (not much help lol). It is really well written and actually helped me understand LQR in terms of this type of craft! Specially in defining the state variables and diff equations. So I thank you for that. I will send you a video of my single axis test as soon as the new parts come in. Also, thanks so much for sharing your software, I always thought trying to implement a state space controller with matrices using arduino would be nearly impossible but I’m so glad I have a reference software to get help from since this will be my first large scale software, I need all the help I can get! Are you still studying at MIT?

@@djredrover That sucks, it is horrible to wait for new components - I hope they arrive quickly! What is the title of the paper? I never released a paper on the project, only a large report - who is the author? 😂 I am glad my work can be of help, you are welcome to write me if you got any questions 👍

@@MrSolidGeek Thank man I really appreciate that. I definitely will need your help down the line. I should have been more clear it is your Masters Thesis called "Modelling and Control of Thrust Vectoring Mono-copter". Really well written. I shoot you a copy of it.

😂😂😂👌

Yes, it redirects the airflow using four vanes at the exhaust, which enables me to control the attitude (roll, pitch and yaw).

Thanks! I am designing a new remote that uses this display and the nRF52. Going to upload a few videos about it soon :-)

That is correct, the one shown in this video is an old model, the new only has three holes. I made the modification to make it easier to assemble, and it turns out it does not make any difference :-)

It is free to download in github 👍

5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it
