I get that the spinny fan like pulls it up but like how does it spin because if I theoretically have a massive fan that spun at extreme speeds will my house fly?
Plus why do helicopters need spinny things when literally every other thing that flies just has wings and an engine. Also if the fan spins why does it spinning pull it up like when it’s on the ground it stays still but when it’s in the sky u can like manoeuvre it 360 like what.

Helicopters use rotors to fly .The rotors create lift by making a low-pressure area above them and a high-pressure area below them, and this difference in pressure keeps the helicopter in the air. By changing the angle of the rotor blades, the helicopter can change how much lift it generates, allowing it to move up and down or stay in one place.
But, unfortunately, just having a massive fan spinning really fast won’t be enough to lift something as heavy as a house. To generate lift, you need something like a helicopter rotor or an airplane wing that’s specifically designed to create a difference in air pressure and lift objects off the ground. The rotor blades on a helicopter are specially shaped to create lift as they spin, and they can be adjusted to change how much lift they generate.
Helicopters use rotors instead of wings because they need to be able to take off and land vertically, and hover in one place. Wings are great for staying in the air, but they need forward motion to work properly.
