Edit: redesigned center fuselage, still can't fix the turrets though

Experimental Aerial Defense Weapons Platform designed to safeguard high-value objects or areas. The AP-120X is armed with multiple AA gatling guns, missile batteries, and a pair of centerline high-caliber machineguns designed to deter or destroy would-be threats.
This craft can soak up a lot of gunfire, but a well placed missile can destroy it in one shot, and this craft's own missiles are less powerful than usual.
Was an old project that I decided to upgrade and improve further on, with decent results, except for the turrets.
If anyone can help fix the weird turret wobble/torque, it would be appreciated.
