We had in St James Gyrodyne a helicopter company that made small helis 50 years agoI do not believe in hoppacopters. There is what we useta call a "Jesus nut" on them. You can see it plainly on the leader -- it is the nut that holds the rotor on.
No other powered aircraft turns into a completely uncontrollable brick if one dinky part breaks.

Oh... One moar thang: It takes both hands and feet of the pilot to just keep a hopticator in the air. A real plane will actually fly itself -- even a Spam Can.
Wait... if your Piper Warrior engine dies, you crank the trim wheel back, and the plane will assume an attitude that will allow it to land by itself if you are incapacitated (possibly without damage if the ground is clear like a golf course).
OK, so I am as high as the Statue of Liberty's nipples...
