Ladies and Gentlemen;

Forgive me if this has been covered before: [Exclaimer: THIS IS NOT A WHINNING THREAD, MERELY A QUESTION! PLEASE DO NOT TAKE IT AS ANYTHING BUT! ALSO, PLEASE DON'T HIJACK THIS THREAD WITH WHINES ABOUT THE MODELLING OF THESE SYSTEMS...START YOUR OWN THREAD!]

I was flying around in the Ki-84 for kicks the other day, and go to thinking. Are the differences between the Mk-108 / Ho-105 modeled in-game?

According to http://www.csd.uwo.ca/~pettypi/elevon/gustin_military/fgun.html,

The 105 is: Ho-105 30 x 113 450 rpm 750 m/s 44 kg
The 108 is: MK 108 30 x 90RB (312 g) 600 rpm 505 m/s 60 kg

Now, the difference would be imperceptible to me in game, so I was wondering if any of you guru's would know. They seem about the same to me, as far as hitting power, but according to that site, the Ho-105 fires slower, but at a faster muzzle velocity (I'm no physicist so I won't feign knowledge of mass and kinetic energy etc, and I haven't taken a real science course in over six years!)

Also, I found a site you guys might be interested in:

This one shows pictures of Japanese Army/Navy weapons, click on the links and it'll show larger photos with some information:
http://www.sam.hi-ho.ne.jp/ki-44/english/data/jan-gun-e.htm

This one is the index of that page and others, interesting stuff like sights etc.:
http://www.sam.hi-ho.ne.jp/ki-44/index.htm

I'm not vouching for the credibility of these sites, as I don't know enough about them to prove or disprove the information provided. Give me a site on Afghanistan culture and politics, no problem. Aircraft sights and weapons data, no way!

Hope this is useful to you...just wondering about the weapons...

Well here's what this site says:
"Late in the war, the Japanese Army had a good 30mm cannon in the Ho-155, sometimes erroneously referred to as Ho-105 or even Ho-151. It was a scaled-up derivative of the Ho-5, itself a derivative of the Browning. Late in the war, the Ho-155 appeared on bomber destroyer versions of some of the best Japanese Army fighters, such as the Ki-61 and Ki-84, but it seems to have seen little combat use. The gun compares favourably with the German MK 108. At the end of the war a lighter, shorter version was developed, the Ho-155-II, but this version never saw combat. It was a far cry from the early days of the war, when most Japanese Army fighters were armed with two rifle-calibre machineguns!"

Apparently Rate of Fire is lower but muzzle velocity is higher. Says that it saw little use but sounds like it did quite well.

Seafire; (was wondering if anyone was going to respond)

Yes! I forgot about that site...it's in my favorites, but I didn't look at it. It's a pretty good site I think.

So, basically, it's a really scaled up version of the Browning? That's interesting...also, I guess it is really the Ho-155...

I wonder if the muzzle velocity difference is modelled? I suppose that would mean less "lob" action when compared to the Mk-108, right? Interesting stuff...I'd do all those nifty tests that you guys do (shooting at smoke stacks from a set range, etc) but I don't really know how to get those little dots indicating round impact points.

Just curious...if anyone has anything additional to add, please do. Thanks!

In your game folder (usually: C:\Program Files\Ubi Soft\IL-2 Sturmovik Forgotten Battles ) you have the conf file Open that file (with notepad).
You find something like this:

[game]
Arcade=0

change that 0 with 1 save settings and start the game.
