Gladius Control Surfaces and Atmospheric Flight Model in 4.1 PTU
The Gladius appears to have gotten some special treatment!
Currently in the PTU (4.1.0-ptu.9627438)
The Gladius has had it's control surfaces and atmospheric flight model added!
The ships Ailerons, Elevators, and Rudders are all animated accordingly.
And testing between patches the ship flies a bit differently in the new patch!
I'd suggest trying this out for yourselves!
