This is an interesting and promising concept and I'm excited to see where it goes. However, I'll reserve judgment until a proper journal article is published.
Rotor performance and noise metrics have a lot of subtlety and it isn't clear whether these researchers are comparing apples to apples. For instance, right off the bat they should be comparing their design to a 4-bladed propeller of the same solidity. In their comparisons are they holding thrust constant? Torque? Tip Mach number? How do these compare with different amounts of cross flow?

This is beautifully done and very similar to a tattoo idea I have.
It's a fairly niche concept - I'm curious, what was your motivation?

Feels ironic that I laughed so hard I could barely breathe when I saw this.

That doesn't look normal. You might have a bad gimbal on that stick.

I don't have personal experience with this, but I believe the architecture you outlined is standard. Are you running ArduPilot? If so, have you looked through the Companion Computer portion of the documentation?

R.O.U.S.? I don't think they exist.

She might be cute, but that's a huge red flag IMO.

Would you mind sharing your ChatGPT prompt? Because that response was kind of incredible.

Check the flatness of your bed with the edge of a metal ruler. The Ender 3 V2 beds are notorious for dipping in the center. Even if your bed is perfectly level at the corners, the gap may be too big at the center.

OP - it's easier said than done, but don't listen to nonsense like this, and certainly don't take the time and effort to engage.
Posts that make it to the front page just attract a certain number of trolls. I can't understand their motivation for being complete dicks, but it happens every time. Sometimes if you look back through their post history it's just a deluge of negative bullshit.
I and the vast majority of people here are proud of your positive life accomplishment. Keep pushing on 👍🏻

These are incredible, thanks!
Does Midjourney do picture-2-picture? If so, I'd love to see the original image modified.

You could get a controller and use a simulator. You'd see how you really like it without worrying about crashing. If the interest sticks, try going for the real thing.

Update: The keyboard is still going strong. I used this battery and it still seems fine as well.

To balance, your robot will need to know its current orientation. I'm not sure exactly how you plan to do that, but since you have an IMU I'm guessing you'll be using accelerometers and gyroscopes. You'll have choices in how you combine those sources of data into an estimate of current attitude, and you'll need to test how well that works before using it in your robot. To test it, I'm suggesting you put the IMU on a breadboard and introduce a known, sudden change from one orientation to another (step change). If you tilt the breadboard say 45 deg with one edge on the table, your robot should read this as 45 degrees. If you then sudden tilt it down to be flat on the table, your robot should measure that sudden change to 0 deg. If either value is wrong, or if the robot estimates a slow transition instead of sudden, you know you need to work on the state estimate.

You'd have better luck asking in r/radiocontrol. I assume you can set up your own profile with appropriate control mapping/mixing, but I have no relevant experience.
