Will the Sabre be able to have a full gimbals setup? To what extent can we gimbal the weapons?

Absolutely, it has 4x S3 hardpoints so you can rock 4x fixed S3's or 4x gimballed S2's(or a mix of both) if you desire. Whilst they are gimballed there are obviously some restrictions due to the locations of the weapons, which infact can completely retract into the hull. The Sabre was designed so that all weaponry can be retracted inside the ship to keep its cross section profile down, so the nose guns tuck backwards and up into the body. The wing mounts retract into the wings and panels cover them up, all the missles are stored in internal bomb bays.
