Funny thing is, someone posted about that very project just yesterday

It's a crowd funding project - doesn't exist - and if it ever does, as rarely do crowd funding projects meet original specs, it's too light and small, resulting in poor navigation. Which is basic physics that all large popular drone manufacturers understand - because they hire people who went to school.
Small light weight drones can only be used indoors in very large open environments.
Besides, it's a crowd fund project. Won't exist anyway
