I think the biggest issue is not 'if' you can hover an edge in RF2 but more the fact that you are hovering a plane governed by unrealistic laws of physics (such is the limitation of RF2 and its 3D aerodynamic physics).

This means that whilst it may be hard to do - you're getting used to controlling a plane in an unrealistic environment. I switched from RF2 to AFP and found them very different at stall speeds/snaps/hovering.

Just my opnion.
