Edit by pedro16797:
It seems like activating AG4 causes a huge roll and yaw instability in the craft, apparently for no reason since both missiles assigned to that group are symmetric.
Activating AG5 removes the instability but absurdly increases the drag of the craft, even after closing the bay.
Activating AG6 restores the drag, allowing the craft to pick up speed again.
