I’m also a pilot.

In fact I’m a commercial helicopter pilot holding an ATPL license. I'm adjusting my observation to be a 65° turn. Had a better look at the video on my computer vs my phone, and I can see the ADI go past the 60° white mark while still turning a bit more as it goes out of view.

A turn this steep can be dangerous due so the high G-loading of the disc, as well as the risk of getting into a low-g situation and inducing mast-bumping.

Doing aerodynamic moves in a two-bladed teetering hinge rotor system like the Robby is always a great way to get killed. Although 65 degrees is substantially less dumb than the 80 as I originally stated.
