I like those sounds, could you post the original sounds, i don't own dcs world but i'd like to use those sounds in Flaming Cliffs 2.
Here is a link to my latest soundpack version for FC2.1; that soundpack is still pretty good but the DCS:WORLD version I'm working on is way ahead of it:http://www.lockonfiles.com/index.php/files/
One reason why these example sounds work so well is because the DCS:WORLD sound engine is more developed and flexible and has better sound-modding options (plus I have made no alterations to the .sdef files within FC2.1). As a result, the original files will work very well within DCS:WORLD but not so well within FC, as the sound environment configuration they work within is totally different.
But the files will become available in a week or two within an initial soundpack created specifically for DCS:WORLD BETA 188.8.131.52. It will not work properly, nor fully within earlier FC or DCS versions, and I won't be making a soundpack for earlier versions (but will be for the A-10C and Blackshark add-on versions within DCS:WORLD).
My present view is that DCS:WORLD is far ahead of FC2.1 and works in much superior ways, so it's time to migrate to it and get more familiar with it.
The BETA version is free, it's available to anyone, and you can download it from ED's DCS:WORLD webpage, install it, and it already contains the Su-25 as a flyable. If you can run FC2.1 OK, then it does not seem to require a more capable PC in order to run DCS:WORLD, OK.
There are already lots of genuinely mind-blowing realism mods appearing for it, stuff that goes far beyond the current FC mods.
I was very disappointed with FC2.1, in many ways as a modern tactical air combat flight simulation, and I was also disappointed with DCS for the same reasons.
DCS:WORLD BETA has totally changed that, and from what I've seen so far I'd say DCS:WORLD will turn out to be the largest, most advanced, and also the most enjoyable modern air-combat flight sim released by any developer -- ever.
And so it should be as it's taken ED almost ten years to get it to work credibly, as a tactical air-combat simulation. So if I were you, I'd consider migrating to this free BETA version soon-ish (let's not forget that it's a BETA, so has it's bugs and quirks still). Basically, it's ready to use, and to mod, and to make missions and campaigns within. It was a gutsy decision for ED to go to an open BETA version process, as I think it's going to make a huge difference to the quality and the speed of development of what comes next.
I'm about to pre-buy DCS:WORLD based only on what I've seen of the BETA, so far, and if it had been merely a re-hash of FC2.1, with DCS clothes on, then I wouldn't even consider buying it.
It may look a lot like the old FC2.1 and prior DCS versions but in terms of modern air-combat tactical simulation and potential DCS:WORLD is a whole different beast.
