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.

Like when it’s on the ground you can spin the fan and it won’t go anywhere but then when ur in the air u have a stick that can move to go anywhere
