Atmospheric Archwing Animation is Broken

[ApathyPersonified]

While the archwing flight animation in space seem pretty smooth, flight in the open worlds is kinda choppy in some instances (namely: afterburner movement). When moving backwards at max speed, it looks as though you are still moving forward. There's also no ascending or descending animation at max speed.

Movement in space looks awesome, so one would think it'd be an easy fix (not that I would know).
