You would need to mess around with the CSWeapon.xml to get the correct angle/direction of fire. BUT. They will be a fixed angle/direction, you can't have them moving.

It is described like this in the CSWeapon.xml file:

<Station name="Nose" params="0,9,0,0,-0.039,0,200" />
<!-- Station position (x,y,z) meters, angle of incidence, ammo units quantity -->

In the above station, the guns are angle up at about 3.9 degrees. It gets confusing that a negative number is up, but messing around with them, you will get more familiar with the way they are.

This one is from my A2A WOP3 Spitfire mod:

<Station name="Left Wing Outer" params="-4.0,0,-0.5,0,-0.017,0,200" />

As you can see, I reduced the angle to 1.7 degrees, so they were lining up the gunsight.

Would this work in multiplayer (i.e. with someone else flying the helicopter) or with FS Recorder?

In multiplayer with both players having Weapon for FSX? Possibly (but you can't shoot others players down). I have no idea how well it would record in FS Recorder, but you might be able to shoot the another aircraft down.
