RAF Mk2 - early war Spit MkIa, Vb and Hurricane:

USN Mark VIII, all early to mid war US Navy fighters:

Revi 3D - Bf109E, Ju88A, Ju87:

Soviet BPB-1 - most mid to late war Soviet fighters:

Now the small problem. It appears the Spitfire sight is incorectly calibrated (the zero is too low and slightly left - see pic):

Could someone check their install to see if this is something I have created (I'm pretty sure it is not). If it is an existing problem, could someone tell me how to reset the POV for the pilot and I will fix this.

Open the plane in OPS (might have to open the cockpit model instead). Click on the pilot model. This will highlight the gunsight tool (looks like a little green circle with two red "tracers.") Click on "View from gunner's perspective." You'll see your reticle framed by a yellow "target box." Use the arrow keys to center the reticle in the very center of the box, and you're done!

On the spit sight, the screen shot you have is not a good judge of the aiming. it looks like you were losing altitude (nose appears to be below the horizontal plane).

In that pic, that's why the aiming appears low. To really check you need the AH dead level.

If I remember right most taildraggers were put on a tail stand until the AH was spot on before they messed with the bore sighting.

Next question- at what range are the guns sighted in for? Test firing at too short of a range results in hits being too high, and at too long results in hits being too low.

Example. Depending on the round, if I set my 30-06 to be dead on at 200 yards, it will shoot 1.5-2 inches high at 100 yards, and drop over a foot at 400 yards. If I sight it in a 400 yds, it will be almost a foot too high at 200-250 yds.

The muzzle velocity and bullet weight determines the amount of drop and thus the sighting requirements. Because of the weight of the MG rounds, there is a significant drop that needs to be compensated for.

The above example was using a medium grain bullet. If I was to load a 300 grain bullet ( not available commercially btw), the drop at 400 yards would be several feet.

Anyway, if you're putting together some kind of little pack for proper sights, let me know and I'll send it over.

The spit gunsight works fine for me. In my updates to the spit I have not moved the pilot.
