Check out this video from amazingdiyprojects as he takes his homemade multi-rotor copter out for its first manned test flights. Yes, it looks like a death trap. He is just sitting there surrounded by dozens of angry, spinning rotors.
He admits that he should be wearing some protection, but he explains:
Regarding wearing MC suit and full face helmet etc. This project is about obtaining the precious feeling of freedom. 10 min at a time LOL… I know, but still… so wearing a fortress would be counterproductive. I have tried to build in safety in the structure itself, so that I can feel FREE. Goggles and ear protection or headphones is a must. All other clothing is OPTIONAL. I’m flying in an unpopulated area, so I just might try flying nude. I promise to NOT make a video documenting that flight… LOL!
It is a 25 minute long video, so after the first flight skip to 15:30 for the second flight, and some first-person point of view footage at 22:30. While it looks quite dangerous, it still looks like a lot of fun.
