This appears to be a video of a homemade airplane made in China by a farmer called the “Shanzhai huaxiangji” via Kottke. It’s hard to tell what’s actually going on, it could be a fake but there are some interesting things about what it’s called — more about the airplane (name) here. “Shanzhai” means homemade or counterfeit and there are tons of other “Shanzhai” projects literally floating around! This could be a Shanzhai Shanzhai if it’s fake!
