Why Does Fw 190 Have So Much Dispersion?

[funked]

I fly mostly Spitfires and Fw 190 with 2 x MG 151/20, and I have the distinct impression that the 151 scatters a lot more.  

I can't prove this, and have no idea how I could prove this with available tools.  But I have fired a lot of rounds in both aircraft and there is most definitely more scatter on the 190 cannons.  

Yes the slower, lighter, Mauser rounds should drop a lot more, but what I'm seeing is not drop.  I can't think of any technical reason why there would be such a big difference in dispersion between the two gun types and installations.

Can HTC take a look at this and make sure there is not an error in the code somewhere, like an angle in radians instead of degrees or something?

And if there is no error, could HTC kindly give a hint as to technical reasons for such a large difference?  Or at least tell me that the difference does not exist, and my observations are faulty (which is entirely possible).

Funked you better hide yourself.
Uuups too late, I already hear them coming

I'm sry but your not allowed to question anything about LW planes because the 5 year olds running around on this board will call u a luftwhiner and tell you to buck up, get over it, or anything else their feeble brains can come up with.

I'm still waiting for someone more skilled than I to make a target range map.  A terrain with vertical walls different distances from the runway placement where true dispersion could be seen from hit marks, rather than trying to somehow judge distance of tracers through an external view.

[Fatty]

PS - Unbunch your panties, buck up, and get over it.  Luftwhiner.

[funked]

Yeah that's what I mean by tools Fatty.

Funked... is this concerning the Dora9 or all 190 variants?

If it's all 190 variants... I can't see the difference between any airplane and I use the same gunsight for all my planes.

If it's just the D9... I dunno, but I've got a film where I down a B17G from 600yds out...

The answer is very easy:
some dispersion enhances your chances to hit the enemy plane.

Oh damn ! I'm right and wrong. For the good gunner this is bad, for a bad gunner good. I'm a bad one

I'd love to make a gunnery range map.

But HT won't tell me how long the runway is.  

Or any other building for reference. Measuring by using an aircraft as a ruler(known measurements, span, lenght, etc) is out of the question because not everything is to scale --> The Panzer chassis is dwarfed by most planes in AH, however it is just about as tall (about 9 feet) as most of the smaller planes, and taller then the 109.

Sooo....

Get someone to bail on h2h, and run down the runway til icon is 100, 200, 300, etc yards away?

Heya Funked,

I'd assume that they're basing dispersion on the RAE or PRO docs showing the dispersion pattern from a captured MG151/20 (i do believe from a Fw).  I've heard references to this document (i think on another RAE or PRO document), but i have not seen it myself.

Signed,
Goobe.... errr buile-

p.s. lol, i just saw 'Naudet' refer to it in this thread: http://bbs.hitechcreations.com/smf/Smileys/default/Forum9/HTML/002037.html  
Maybe he's seen it?  At least it would be a way to either check the dispersion or show what a used MG151/20 will disperse like.

funked, to prove it is very easy.
Just set up same convergence with Spit and 190 guns to 300 yards, and once at runaway switch on zoom and adjust it to maximum.
Now start firing bullet by bullet (tracer by tracer). You'll notice the difference.
Yesterday I did some tests like this with 190A5 4x20 and Nikki 4x20. The restult for the A5 was NONE of the tracers crossing the exact center of the gunsight (default). For the nikki, 2 of every 3 shoots crossed the center.

[Wmaker]

Yep, noticed the same thing myself funked...109's engine mounted cannons seem to have very much dispersion too...

Actually funked, the speed drag shouldn't be that much more for a MG151/20 round then for a Hispano, the speed difference is about 250 feet per second, this little difference, enables the Hispano in AH to penetrate 80mm Armor aswell.

Last night I went HO with a B17 in my G10, 1x20mm and 2x13mm, hit him all over the body, cockpit and wings with more then 50x20mm rounds.
He started smoking from his engines but nothing more, the MG151's are undermodelled, not only in dispersion but in actuall dammage.
It took about 20x20mm Minen shells to kill a B17 in R/L.

And no, it's not bad connection, I have 0% (zero) packet loss to hitechcrations.

It took about 20 of what kind of shell and where did they land?

1.  The AH guns are a mix of tracer, AP, and mine shells I believe.  Not all one type.

2.  You spread your shots out all over the plane.  Any buff can take huge damage if you spread it around.  Concentrate it in one plance and they die plenty fast.

I don't think your evidence supports your conclusion.
