Uh... didn't ALL P-47's have 8 machine guns? I've never heard of one with 6... but the P-51D did have 6 guns (B & C only 4).
Also, a realistic convergence of well under 200 meters (even just 100 meters would be more realistic than the current pre-war RAF config which was not maintained beyond first combat experiences, and the Germans already began with smaller convergence range) would make not only Allied fighters' guns, but German wing-mounted cannons on 109E and 190 more deadly.
Oh, and get rid of the wing cannons on 109F, they did not have any even as add-on packs (unlike 109G), only the Motorkanone.
On the P47 with 6 guns - according to Gunnie (who codes vehicles) the ground crews would remove the outermost guns to save weight if the plane was carrying rockets or bombs.
Convergence was 200m, then someone (Remdul?) suggested that it should be longer because the veiw distance is longer on plane maps. It then got changed to 400m before the 200m setting could be tested.
There is a 109F without the gunpods in existance - however it has the unfortunate problem that it is called
bf109f4_trop while the one on the maps now is called
bf109f4. Thus when Lobo went and added the plane to the maps - he just picked the first one in the list.
