Convergance for guns
« on: April 14, 2011, 04:17:31 PM »
Does anyone have a graph or something to show me the range to set certain weapons? having a hard time trying to figure out how far Browning 50s or Ho-5's go etc.

Basically want to know the ball park area to set my guns, for example a spit8 has 303s and 20mms, do I set the 303s to 350 and 20's to 425?

No easy answer for that, because convergence settings depends a lot on your flying and your usual shooting distances.
In a pure .303 fighter (like Spit or Hurri I), you don't really want to shoot much beyond 200-250, so a close convergence (like 200) makes a lot of sense. On the other hand, if you are flying less maneuverable but fast, and more heavily armed fighters in LW, you may often have to fire at longer ranges.

In the case of the Spit 8, I have the 20mm at D350 and the .303s at D200. The Brownings are not very efficient at long rnages, so I shoot the Hispano's only, using the machine guns only to augment (or substitute) the cannon firepower at close ranges.

For most players, I usually recommend leaving all guns but the rifle-caliber pea shooters at D350.

Ah ok, I've had everything set for 350, seems it works out alright, I read some set for 650 but I don't see that happening.

Consider the distance you typically hit at.

Best advice I can give you is to set conv. to or near the distance you most often shoot from.


   I rarely shoot past 200 yards so it make no sense to have my convergence set out to 400yds.

 Go into the training arena and use the .target command,you can set the target at various ranges and can observe the different bullet patterns you convergences have.


  hope that helps.

Much appreciated, I will have to do some more TA flights and work out the general dynamics, so far best I figure is 350-375 is roughly where I start shooting, unless I can get closer, but I haven't yet to figure out dogfighting to get close enough to 200.

When the icon changes from 400 (500-300) to 200 300-100) your range is 300. Set your convergence for 300 and close until you get the change, then let them have it !

On Spit8 I got my 30 cals set to 275 and 20mms set to 300. I usually fire at 400, works well.

Generally speaking, trying to set and shoot cannons much beyond 300 is not going to work well.

Yeah I made a few 600 Sprays and obviously ended up no good, straight and level you have a shot to ding up a plane but nothing fancy,
I try to end up on a deflection shot around when target changes from 400 to 200. But I still am having problem learning the balistics.

From what I gather so far -
German Mk108 is by far the worse, best set for 250
Russian 20mm - 250
Japanese HO-5 best set for 250-275
German Mg-151 best set for 300
German 13mm best set for 300
Japanese 13mm - 300
American 50 cal - 350
American M2 - 350
British Hispanos - 350
British 303 - 250

Is this roughly a ballpark figure? I would like to write this down once finished so I can change the planes accordingly, another question is on the convergence of for example the 6x50 cals, Would I have all guys aimed at 350 (example) or do I stack 300/325/350?
I would assume to have all guns set for the same convergence, only plane I can think that would require more then one convergence is the P47 based on the 8x50s, but I haven't flown a Jug really to know this.

I would not use so many different. It doesn't help that much. After a long time of tinkering & testing,  I finally have 350 on all my guns but .303's (and the Me 262, where I use a special "shotgun" setting)

For the scissoring convergence, see this thread http://bbs.hitechcreations.com/smf/index.php?topic=291419.5 with a lot of data and a few very illustrative graphs.

Thanks, and I apologize for making a thread which already was answered before hands, I didn't use the search to well! :)

No worries, the search fuction is currently messed up quite a bit anyways. If you don't find the answer, never hesitate to ask in here  :aok

I like 275.  The trick is to discipline yourself to shoot as close to your convergence as possible.

I like to set my convergence to max range when making an attack run on ground targets.

Perhaps it's merely the placebo effect, but I seem to have a better time dealing with the ack when I have that extra few hundred yards as a buffer while engaging.
