Not again. Could everybody please read their Prouty before coming up with that again and again and again? It has been debunked several times here. The Robinsons have an offset of 72°. Not 90°. Can't be gyroscopic precession. Other helicopters have other offsets. Yes, Smarter Every Day got it oh so wrong, too. He isn't that smart. Otherwise he would have talked to somebody who actually knows something about it. And yes, the FAA helicopter handbook gets it wrong, too. It's lies to children. Simplifying things to the point where it is wrong.
In a vacuum you would have that effect, but aerodynamic effects are way stronger and therefore gyroscopic precession is not important on a rotor. It is called phase lag.
And there is no centrifugal force either. Centripetal force is the real thing. Goes in the opposite direction.
