P-38 Convergence
« on: April 23, 2009, 11:26:01 AM »
As my love for the 38 grows ever deeper. I wanted to see what some of the more seasoned 38'ers have there convergence set at. I've done a little reading and wanted to poll the audience. Hints, tips, suggestion anyone?

I have my MG set at 600 and my cannon at 650, but most have the convergence set way in.

The horizontal spread is never going to be wider than the nose, it is vertical drop that you are trying to overcome. With my convergence set way out, it allows me to rate my nose a little bit less to get a gun solution which equates to less G and more E overall.

If you're serious about learning the 38, I would be willing to work with you. However, my time is severely limited lately with work, wife, and 2 sick elderly parents that require more and more time of me. If we book a time in advance, I will be there.

Right now I have it set at 600 for both. I just don't seem to get the same killing power that others seem to in it. Obviously that could be a ton of reasons. Hoping convergence might be one of them. I will try moving it in some, maybe staggering it a bit.

Thanks, and please continue to post fellas, I am open to suggestion

Honestly, there is no real reason or need to change the convergence on the P-38 guns as they are all center lined.  Whatever the default convergence setting is, that's what I had my convergence set at.  It's basically a personal preference sort of thing in regards to the P-38.

I'm not really a full on Delirium protege so to speak, but as an avid fanboi/38 wannabe I also have my mg's at 600 and cannons at 650. :)

You'll probably find that convergence has little to do with it though. If done with consistency 10-15 minutes offline shooting on the practice drones from various angles before entering the MA will give you good improvement. When I was disciplined about it, I saw some awesome results.

Don't fly the 38 much except for maybe in the DA for practice and the MA's for jabo runs... but this is what I've found.

Since all the guns are in the nose not a whole lot of conversion choices are needed. The only one you'll really have to mess with is the 20mm. I have mine set out a bit farther to keep it a little closer in line with the 50's as it travels. To short and it drops to fast, to long and it travels slightly above the 50's.

There are many posts on how 20's travel through the air. Trying to find that perfect trajectory to meet up with your 50's at your chosen conversion point (or WHERE YOU NORMALLY TAKE YOUR SHOTS) is not easy.

Use this thought process for setting the 38's 50's then test it out using the .target command and you'll find I'm right.

As the bullets leave the guns from the nose of the plane they are in the shape of the nose which is maybe 3.5 feet wide (?)



The convergence is set to meet at one point like the tip of a cone. After they meet they extend out in the other direction creating another cone. The farther they travel the larger the cone on the other end. Well you only started with 3.5 feet so twice the convergence set would end up the same size as the nose again.






Because of this I like to set my 50's at about 175 to 200. At 200 they hit like a laser. At 400 they hit like a shotgun.






Any farther out and they spread into a larger cone but you have to keep this in mind.





This is where setting your 20's comes in handy. Try to match the 50's dropping with the single 20 for the best convergence. Basically all the bullets will stay in the same path and your hit sprites will all be in a circle I like to call "The Cone of Silence"  :lol

I use 175 for 50's  (=D300 nose cone) because my shots are normally taken a little closer and 400 for the 20's

i thought that since the convergence also brings the rounds together where your sight is, that if you set it out farther, it would sort of "lob" the rounds, so they'de higher out there?

That's what the bottom of the last illustration A8TOOL posted above shows.

This one:



Convergence too close on a far target and the projectiles fall short.  Convergence set far out on a close in target and the projectiles potentially arc over the target.

YES exactly. i saw that after i posted mine. i used to keep all my guns on the 38 all the way out to 650. but i kept missing close shots. brought it into 450, and i hit better, but didn't want to bring it in much closer than that.

Yep, I find myself shooting below the target on straight 6 shots of 600 or less, but knowing this I find that I can do just as good. Personal preference there I spose.

I brought the MGS, in to 550 and the cannons to 575 and I already notice some good results. Thanks to all of you for your help. I'm sure I will have more 38 questions down the road.

Actually, I have a little trouble getting a good roll over at the top of a climb to come down on someone. Hurri's been giving me fits too. Back to the drawing board lol.

turn combat trim off as you get slow and roll over the top, it will roll a lot quicker... well not like a Folk-Wulf, but quicker than normal   :D

I find that I have no trouble getting bullets to converge on my 38.   

That was your question right? :)
