littlebird gatling guns accuracy

[Leon86 13]

Is it just me or is the littlebird way more precise on 4000 compared to 2000? Doesn't make sense to me.

[armapaddy 10]

It does make sense because you are shooting twice the amount of bullets in the same amount of time so you are more likely to hit your target when you fire.

[ryguy 10]

armapaddy's pretty much got it.

[Uglyboy 10]

Not really, he was referring to the dispersion of the gun on 2000 rpm ( absent on 4000 rpm ) not the chance to hit the target when firing more rounds.

I don't think the engine can actually render that rate of fire. So maybe the higher RoF drops some of the ballistic calculations to keep things doable.

[max power 21]

On future weapons, they had some advocate of the minigun saying that at super high rates of fire, something weird happens to hit percentages. If an FN MAG fires 1000 rpm, and a minigun fires 4,000, the hit percentage isn't 4 times more. It's more like 8 times, or so they say (IIRC). I'm not sure what this means or why, but I know that BIS watches future weapons. Maybe they pulled in the dispersion a bit to compensate for that.

May I ask out of curiosity, are the miniguns on the littlebirds so accurate in real life?

I only ask because looking at real footage of miniguns, all you see is a huge cloud of dust and carnage wherever the bullets are hitting, but on Arma 2 you need sniper like accuracy to hit ground infantry.

It's almost as if the bullets themselves aren't powerful enough? I'm probably wrong lol, just something I noticed.

I tried to finish a single infantry with this chopper but nu-uh.

If you place the infantry on your crosshair it wont hit since the left minigun is aiming left of the crosshair and right is aiming to the right so...you have to do some weird stuff to get a kill.

Also the miniguns are like 2 little drills just making holes to the ground. You can't really kill stuff with it or suppress a squad of infantry and actually damage them.

An increased "spread" on the AH-6 M134 would be great in my opinion, since at the moment, it's so hard to hit infantry/very light vehicles/static defenses with this thing and those are the only things they're useful against. (It can't even take out a humvee so I put in "very light vehicles" like the UAZ)

Would be nice if the M134 rounds had more of an effect. I'm guessing they use incendiary ammo or something irl.

[max power 21]

According to a source I found, on a hard mount, the m-134 has an accuracy of "6.5 mils, 80% circle" at an unspecified range. 6.5 mils is a cone angle of 0.367 degrees, or 0.006 radians. I assume that to mean that 80% of the rounds fall within some circle corresponding to an angle of 0.367 degrees at some range. By contrast, the compendium of modern firearms suggests that the dispersion angle of the FN MAG is 0.47 mils, and of the Minimi is 3.652.

This means that the m-134 on a stable mount should fire 80% of its rounds into a 3.25 meter circle at 500 meters, a 1.625 meter circle at 250 meters, or a 0.65 meter circle at 100 meters. It should about 1/12th as accurate as what is predicted for the FM MAG on what seems to be a hard mount, or about 1/2 as accurate as a Minimi on what I assume is a bipod. Again, this isn't really such a great comparison because the range at which the Gatling gun was assessed is unknown.

I always use the ruder to give the gun some more dispersion. Works great agains inf.

[Kristian 47]

Surelly we can spam the M134 everywhere, and hope for hit, but we need some splash damage and dust :rolleyes:

Indeed. On 2000 the hits have a nice spread. I'd like something similar on 4000.

[celery 8]

The 2000 RPM spread seems exaggerated and the 4000 RPM spread seems exaggeratedly sniperlike. Something between would feel the most natural and yield the most effective results.

Let's take a look at the config:

	class TwinM134: M134
{
	class LowROF: LowROF
	{
		reloadTime = 0.015;
		dispersion = 0.015;
		minRange = 1;
		minRangeProbab = 0.09;
		midRange = 2;
		midRangeProbab = 0.058;
		maxRange = 3;
		maxRangeProbab = 0.004;
	};
	class HighROF: HighROF
	{
		reloadTime = 0.007;
	};
	class close: close
	{
		reloadTime = 0.007;
	};
	class short: short
	{
		reloadTime = 0.007;
	};
	class far: far
	{
		reloadTime = 0.015;
		dispersion = 0.015;
	};
	class medium: medium
	{
		reloadTime = 0.015;
		dispersion = 0.015;
	};
};

The inherited dispersion for 4000 RPM is 0.0017. That's almost 9x less dispersion than for 2000 RPM.

Judging by this, it seems to be by design. Why? I dunno. But according to this, the 2000 RPM is supposed to be used for longer ranges; so I guess they want it to be a lot less accurate at those ranges. I don't really agree with it being so accurate at close range though, nor that the player selectable fire modes follow the same rules.

Of course, it's even more baffling considering the single M134 has no difference in dispersion between the two ROFs.

Good find, how do you interpret such a config file by the way? How do you get 0.0017 for instance?

He had to reverse engineer the arma2oa.exe and hack it. It's very time consuming and requires lots of patience.
