From the diagram it looks like the best firing solutions are...

Aim LOW at 200M for maximum concentration of fire. You will still have difficulty with different impact points for deflection shooting, due to different MG and cannon projectile velocity.

Aim dead on for targets at 400M, but notice serious 4.5M DIVERGENCE of cannon at 400M. Almost a waste of time using cannon at 400+, unless you are attacking BIG targets, or kick the rudder left and right.

At 300M MG and cannon still shoot higher than gunsight aimpoint. Also MG and cannon have neither verticle or horizontal convergence relative to aimpoint, but offers a 'spray' concentration of fire. Would be damn near impossible to be able to get combined MG and cannon deflection shots.

No wonder the pilots who got the most kills were also the ones that said get in real close.

P.S. Love the diagram.

There is a reason why the MG FF was replaced as soon as they could with the MG151. The MGFF is a slow rate of fire slow velocity weapon (relatively speaking) and its tough to hit a maneuvering target with it..

That, and it didn't carry a lot of ammo.

Thanks that diagram helps me a lot with convergence settings

Here is a similar image I found around here. Note MG17 not show (I only just realised :S). EDIT: I have also since realised that the MG151/20 in this diagram is not the same as an MGFF, and the trajectories would be different.



and the appropriate page from Flea's guide:

THIS WOULD BE AWESOME I am not sure how intensive the design would be but how cool would it be to have this in the setup screen, where you could visually slide the targets further and closer and then click a button and fire the guns and see where they hit the targets and adjust on the fly before going up.

Wishful thinking im sure with all the things still left to deal with but I would love to see this someday.

Is bullet drop (ie. curved trajectory) modelled in CoD? Looking at the tracers I'd say no.

by looking at tracers i say yes.

I'm only going off videos I've seen but there should be a noticeble curve to the tracers, as the diagrams above show, the guns fire at an angle. If you get too close your bullets would simply go over what you were shooting at. I've not seen this.

I've also yet to see any tracers cross over (this may just be the videos I've watched) at convergence.
