Hello. Add as homemade I didn’t, since it’s likely to fall into “themes” anyway, and there’s nothing to describe here. But the idea is really interesting, I thought for a long time how easy it is to make wheels on my "cessna", and then accidentally stumbled on this article on instructions. It's funny that the article is from a fellow countryman, but in Runet it is not. In general, I think someone is useful.
As I said there is nothing to describe here, everything is clear from the photo. All you need is aluminum cans, an old bicycle camera and small eyelets.
You can leave it this way, or you can modify it using more banks.
If you make a light aircraft from the ceiling, the chassis of which is usually made of a bicycle spoke, then instead of the eyelets it is better to use "tubular" rivets of suitable diameter. If there are none, you can theoretically try to make them from an annealed tube from a telescopic antenna.
