Ian, i think you are referring to the uncaged modeYou can switch the heat seekers out of boresight mode - I think it's shift-8 or shift-control-8? It's in the manual anyway.
I've done some more testing and yes, you can either put two machine guns on one wing and they'll work, or one machine gun on each wing and they'll work. Any more than two machine guns, however, and simply nothing happens when you pull the trigger.
S'pose you could quadruple the fire rate and the amount of ammo and put one gun in each wing, but...
Ian P.
. That's not what i meant with off-boresight. Uncaging means the seakerhead is free to move through the maximum extend of the gimbal angle of the seeker-head. Off-boresight practically means the seekerhead can be slaved to the pilot's view up to a certain angle (guesstimate: somewhere in range of 50 or 60 degrees FOV) sideways, utilizing a HMS (Helmet Mounted Sight), which can be simulated with the Shift 3 option. You aim at a tgt by using your hat-switch to an aircraft at (for example) 10 o'clock high, and have the ability to establish a lock with your heater missile, and launch. The missile will then steer to the given vectors and acquire it's given tgt (with modern techniques of IIR the missile can even recognize the specific tgt by itself.).
