This one is my favorite, a 'cyclocopter':
I don't care as much about the combat as about the efficiency.
That's a big wing airfoil, and it's cheap foam, and it's not as mechanically complex as a helicopter. There is potential here for low-speed heavy lift. I wish they'd included a scale-up of batteries from "Tiny" to "Too heavy to loft", with sustained in place hover times and watts per kilogram as the performance metric.
How about a cardboard plane
That guy is 3 parts genius and two parts absolute madman. He's like Lilienthal and if he's not going to be more careful he'll end up the same way. 15 meters is all it took. When you fail with aircraft it is better if they don't work at all. He is now getting into an area where the accidents will get more severe until he becomes more careful or ends up in the hospital or worse.
It’s a really interesting project, worth checking out the video where he merged it with a companion computer to do computer vision tasks and inject controls straight into the flight controller https://m.youtube.com/watch?v=uaY2G5Kbj_g
He also has a fun YouTube channel: https://m.youtube.com/playlist?list=PLTSCOv-lGtMax-oA4Pnq8OT...
One of the first flight controllers he coded was in Arduino..

He deliberately kept the code in single file and made sure it was still easy to follow.
It's a little work of art and shows in the most powerful way what such a little microcontroller can do with the right code.
Ironically, he says at some point in one of his videos 'I'm not a software guy' and next gives a masterclass about how it is done.
That was freaking cool.
Oh yeah, this'll scratch an itch.
