Their description of the handling does not match what many other real pilots say about MSFS2020, and, as others have said, they are wrong about how the model is implemented. Their description of the stall characteristics also does not match my experience of playing the game.
* It's impossible to snap roll, even in the aerobatic planes.
* It's impossible to enter a flat spin, even with aft CG well past allowed limits.
* Spin recovery is automatic simply by neutralizing the rudder, no PARE needed, ever.
* Single-engine handling is incredibly benign in all the twins, even below Vmca.
I'm not a pilot, but I've spent a lot of time in other simulators. I can't reconcile FS2020's stall behavior with any of what I read in books.
