Can't you build an array of smaller (say brushless DC motor) propellers to achieve the same thing? I could have sworn I saw a guy on Youtube do that and hover around his backyard in a home-made frankendrone comprised of a ton of props
- nradov 5y agoYou can, and hobbyists have done exactly that. But such aircraft are extremely inefficient and only have enough battery power for a few minutes. It's kind of like that guy who tied a bunch of little helium balloons to his lawn chair and went flying. It sort of works but it's pointless and dangerous.
- dreamcompiler 5y agoYes, you can certainly do this. But it won't be as efficient because in general large propellers are more efficient than small ones. So your batteries won't last as long.
