Inventor Shane Wighton of Stuff Made Here made a gigantic metal version of the hand-spun toy helicopter that many grew up playing with, but there was one critical design flaw. Before we get to the error, just know that the smaller version works by spinning its blades rapidly, thus generating lift by pushing air downwards, allowing it to stay airborne due to lift.
Initially, he wanted to add a parachute to the life-sized version, and that was scrapped for autorotation blades that change angle after the helicopter reaches its maximum height. We won’t spoil the critical design error, although it does have something to do with the flywheels and their gyroscopic effect.

As a helicopter flight instructor, I’ll say it’s really fun watching someone brute force their way through understanding helicopter flight controls. I’m honestly really impressed so far! Everything gets more complicated when it spins!,” said one commenter.
