109's 20mm cannons

[GOA_Potenz]

I been playing with convergence settings for the 20mm cannons, but i can't see any effect on it, basicly can't hit anything with those guns, and i'm have decents good aiming skills. always seems to be so high, anything worng with it
or convergence settings doesn't work at all???

The real 109 drivers had a similar problem, especially when deflection shooting. The cowl 7.92mm machine guns had a much higher projectile velocity than the 20mm cannon, which was seriously slower, so if you were shooting at a target with MG, and were hitting the target, you couldn't fire the cannon and get the cannon shells to take the same tragectory as the higher velocity MG bullets. To compensate, there was of course a compromise. I believe the stock harmonisation for 109 E's was MG was set to 400M, and 20mm cannon harmonised to 200m. I believe at that point both MG and Cannon had the same impact point. But again, if you were deflection shooting, the different projectile velocity still played havoc with aiming. Probably why you see so little gun camera footage of German deflection shooting, compared to allied gun camera footage?

The great thing about the damage model now is that the MG's actually do some real damage. I get a lot of kills with the 109's MGs. You can also be so surgical with them as they damage what you actually hit. I use them a lot at a distance as there is just so much ammo you can be real wasteful with it.

Then when you get in real close give it some cannon. But yeah you have to aim higher for cannon to adjust for the drop.

As for deflection shooting, the Emil isn't that easy with the cannons but the later models with the nose cannon and the MG151 are a lot better. The Emil's MG FF muzzle velocity is too slow and I think a lot of real LW pilots only used them for close in with very little deflection.

The MG131 and MG151 of the G6 and upwards had fairly similar velocities (IIRC). And are easier to group together in a deflection shot.

I've read that a vast majority of pilots were actually quite poor at deflection shooting, until gyro gunsights came in. They didn't have hours to train like we do, hitting refly and shooting some more. The ones that were naturals had often had a lot of experience in their childhood with hunting and shooting so learned the skill then.

Well except for the LW in Russia as they had lots of time to learn and lots of targets Walter Kuprinski springs to mind here.

I've always wanted a feature that would simulate the way convergences were set in wartime i.e., where the plane was set on a trestle parallel to the ground, and the guns were tested against targets to see where the shells were actually hitting. Instead it was always create a quick mission, and test it against ain aircraft set to fly straight without killing you while you try to hit it. Then going back to watch your track, tring to remember where you were aiming at said point in track, etc. ad-finitum.

Ah well...guess it burns up the idle time doing it that way.

Try this

MG h-convergence: 500, v-convergence: 150
Cannons h-convergence: 800, v-convergence: 150

It seems h-convergence and v-convergence have switched meanings in game. In anyway, above settings work well for me.

There was a thread over at sim hq about this, apparently revi sight shoots low and to the left, cant find the post but it was quite detailed, if you use ww view on a slow flying friendly bomber then switch to the revi the aiming point is different, rounds strike at the ww aim point not the revi.

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.

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.
