Title: B25H Gunsight Mod
Post by: AKP on June 13, 2009, 10:29:19 AM
Since the gunsights are spread out in the original thread:
http://bbs.hitechcreations.com/smf/index.php/topic,256861.0.html

I am reposting them here.

When I first posted the gunsight mod for the B25H, I didnt realize Photobucket converts the BMP's into JPGS when you upload them.  Even if you save it as a BMP, the conversion process removes the alpha layer in the image file.  So I uploaded them to my comcast webspace... They should work fine for you guys now.

I also posted the original mod by GhostH, and a "pink" version of the mod I did.  There are also direct links to the BMP's for easier download.

Original Mod by GhostH

I took GhostH's sight that I found on the original post and just photoshopped it a little and added to it.  All the range markers are based on his, just made it a little sexier.

I added the range numbers for those of us that need them, and laid it over the US MK9 gunsight.  I checked it for accuracy and it is pretty dead on.  Works best against ground  and sea targets, but if you can get a shot off at an air con that is flying away from you straight and level... its darn close.  Of course if they are inside 600'... no need for the markers! LOL

Here is a shot of it in game:

(http://i98.photobucket.com/albums/l273/woosle_2006/b25h_ss.jpg)

This is quoted from GhostH's instructions on using the sight and bombing in a 25H:

As to bombing, 250 feet AGL, 250 mph, level or a very slight glide, bottom of the sight glass is your aim point.

Come to the TA and try it someday. You can get very good accuracy with low level high speed runs.

And yes that cannon will hit things out to 4k if you have a good sight and your good at estimating range.

And his in-game shot with directions.  These will apply to my modifications also.

Thanks GhostH for making the original mod, and I hope all you 25 drivers enjoy and find these helpful.  I know I have.

At which range do you have to zero the 75mm gun in to be able to use the range marks properly?
sorry if this question was answered before!

What alt is the sight set for?

If you fire it on the deck compared to say 2k, the results will be much different.
Title: Re: B25H Gunsight Mod
Post by: AKP on June 14, 2009, 02:18:28 PM
From what I have noticed... the range markers work best if you are in level flight, or a shallow dive.  If you are in a steep dive, the 75mm has much less of a ballistic trajectory... and you target closer to the center of the gunsight. 

As for what rage you zero the 75mm in at... I have the convergence set at 600...  but that really shouldnt matter much since it is a single cannon and not a pair.

I am by no means an expert with it yet... still learning the particulars of attacking with the 25H.  So if you have found a method that works better, please share.  And... as I learn more, or learn different methods... I will post them.

I don't think the 75 has convergence to it, does it?  It should fire straight ahead.
Title: Re: B25H Gunsight Mod
Post by: AKP on June 14, 2009, 02:43:10 PM
Not sure if it is included in the convergence or not.  I think it is, but I may be wrong.

Post by: Larry on June 14, 2009, 03:02:45 PM
Ballistics for the gun is different at all alts. That is to say if you zero it in sitting on a base that is 5k it wont work the same when you are on the deck shooting GVs.

Sorry if this sounds mean but I don't think AKP knows any info about the range marks since from the looks of it he copied Ghosth's gunsight and just made it look pretty.

Doesnt sound mean at all Larry... its exactly what I did.  I was looking for more info on the 75mm on the 25H and found the sight that GhostH made.  All I did was "make it look pretty".  I did however test it in game, against GV's and Ground Targets and it seems pretty accurate. 

I am by no means an expert on the ranges, nor did I figure out where the marks go on the sight... all of that credit goes to GhostH.  I just wanted a gunsight that had the ranges on it, and one that looked cool at the same time.  Not trying to take credit for anything I didnt do.

I AM however going to spend some time with it and figure out what dive angle works best with the sight (any info you may have on this GhostH would be helpful), and work out some screenshots of what buildings and ships look like in the gunsight at different ranges... since you dont get range info on them like you do a GV.  Once I have those together, I will post them as well.... and hey... that WILL actually be something I did beside dress up the gunsight.
Title: Re: B25H Gunsight Mod
Post by: TOMCAT21 on June 14, 2009, 08:28:49 PM
I checked convergence in the hangar and I didn't see anything for the 75mm.
Title: Re: B25H Gunsight Mod
Post by: AKP on June 14, 2009, 09:09:33 PM
Roger... then its just the forward 50's.  I didnt even think to check while I was on today. 


However, I can report that the range settings on the sight work best in a shallow dive, or in level flight.  Speed was 250... and was not wepping.  Only checked out to about 2K though...  Have not tested the 3K or the 4K marks. (I have to practice a LOT more before I get hits that far out on GV's)  Also... GhostH was right about the bottom of the sight glass being the release point for bombs with a shallow dive angle at 250.  Dead on the mark.


Title: Re: B25H Gunsight Mod
Post by: Ghosth on June 15, 2009, 07:22:53 AM
AKP like you mentioned, level or slight dive seems to be the most accurate.

I set and tested mine at sea level, since the longer ranged shots were designed for killing ships, lvts, etc at sea level.
2-4 B25H's can totally trash a fleet in one pass with just the guns with good pilots and a good sight.

As to how I determined distance, that was the tricky part. I spent a lot of time with the .target command.
Some of it parked, some in air. working with different distances, zooming for aim, un-zoom for fire etc.
Test marks I'd actually put on my monitor with a sharpie, then I'd tab to paint to put them into the sight. Then save and load the sight and test to see how close they were. 

Personally, I'm tickled pink to see someone pick up the ball and run with it.
Mine was not intended to be anything fancy or long lasting, it was just something quick and dirty I whipped up for my squad members and myself. Then ended up sharing with those interested.

Thanks again GhostH!  You did some really great work to dial in the gunsight. 

Ok... I put together some shots of a CV at different ranges as seen through the "GhostSight".  Since its hard to get an exact range on a ship... I made my son sit on the deck of a carrier in the training arena while I made passes at it with my cameras rolling.   :D

Here is what I got:

(http://i98.photobucket.com/albums/l273/woosle_2006/B25H_4000b.jpg)
This is a shot at 4K with the sight lined up dead center on the CV.  Note that the CV FILLS the gunsight from end to end.  I use this as my indicator for this range.

(http://i98.photobucket.com/albums/l273/woosle_2006/B25H_4000a.jpg)
This is at 4K again, but this time with the gunsight lined up at the bottom of the vertical line... the 4000m aiming point.

(http://i98.photobucket.com/albums/l273/woosle_2006/B25H_3000.jpg)
Here is the CV at 3K.  Note that if the 3K aiming point is placed halfway up the main hull, the top of the mast is at the 2K aiming point.  Again... best indicator for this range that I have found.

(http://i98.photobucket.com/albums/l273/woosle_2006/B25H_2000.jpg)
Here we are at 2K.  I have the 2K aiming point placed halfway up the hull again.  This puts the 1K aiming point just about at the top of the stack.

(http://i98.photobucket.com/albums/l273/woosle_2006/B25H_1000.jpg)
Finally we have the CV at 1K.  Note that the island just fits inside the inner circle of the gunsight from top to bottom.

Of course... the best way to get a true range would be to just ask your opponents to wait on the CV deck as you make your bomb run...  but somehow I dont think they will be very keen on it!

Hope the screen shots help.

I had ghosth's gunsight and used it, but had terrible luck ranging with it on ships because no reference points. I'll give yours a shot! Thanks for all the screenshots and ranging info! Plus the rings/bars definitely help place a CV in the sights.


One thing, though... I know you were just taking screenshots, but when really using these things, don't forget to LEAD the target a little! It's moving forward FYI :)
Title: Re: B25H Gunsight Mod
Post by: AKP on June 15, 2009, 09:48:14 PM
Good point Krusty...  the 75MM is a LOT slower than a machine gun round, and if you are firing from 3000+ the ship wont be there by the time the shell arrives.  I experienced this first hand today...  so the next exercise will be developing a lead system to share.

Although... I took down a DD in 4 or 5 shots with this today.  (The stern almost took my wing off as it was going down.)  So I have the lead down.... its about a boat length at 3000+  Just have to get some screenshots to post and some reference points in the cockpit to others can line up easier.

The main trouble I have is I usually end up heading into the attack run alone... and every gun in the fleet turns on me... so even if I get some good hits in, Im not going home  :x   Need some other 25 drivers to go with me! 

I am kinda making this my personal mission... so as I get more info, I will post it here for all to share.  And if anyone wants to add... please do!  Thanks for all the support guys

Excellent work on the ranging screen shot's AKP.
That's going to really help a lot of folks learn to dial it in.

Really good to see someone stepping up and giving back to this game we all love,(and hate, and love to hate.)  :)
Just downloaded the white version of your updated sight.

The hard part is getting that first shot on target at 4k. From there its just slowly keep dropping the elevation, watching your hits, as you get closer. Your range screenshots are going to make a huge difference on that.

Yes a 2 or more B25h's working together will do much better.  4 of them with a scissors attack would be devastating to a fleet.

Ohh and I always preferred to hit the cruiser first if possible, taking out as many of the manned guns on the first pass.
Much better chances for survival.

I don't think the 75 has convergence to it, does it?  It should fire straight ahead.

Did you forget trajectory?  When you set the convergence, you also set the point at which the projectile(s) crosses the crosshair and either continues on its path or or down.   
Title: Re: B25H Gunsight Mod
Post by: Ghosth on May 30, 2010, 10:13:35 PM
Loon is correct, all guns have vertical as well as horizontal convergence.

A little use of the .target X command can prove that in moments.
Some guns benefit quite a bit from pushing the convergence out.
B25h, iL2, Yak9t just to name a few.

You used to be able to set convergence on it when it came out. I do believe that it was done away with in a update.
Title: Re: B25H Gunsight Mod
Post by: Ghosth on May 31, 2010, 07:49:38 PM
My bad, appears that convergence on b25h does not effect the 75mm.

Was able to see no discernible difference in trajectory with convergence set at 650 or at 150.
