I have currently been able to get a lot of info besides purchasing the IRIS model which is IMHO really WOW!!!
The USAF is currently training on these from my info. I have never designed an AI aircraft so this would be a new venture for me but I am willing to try but don't want to waste a lot of flying time in the design studio if someone more knowledgeable than me is working on this. Please give me a "Heads UP" if it is being done. I looked at the four pages here and didn't see it. Also anyone doing Vance AFB at the moment?
Scroll through the pictures and you'll see that it is quite far along. I would imagine that LOD1 (the most complex model) is nearly finished. That's the easy part if you can believe it. It's going back and creating all of the lower level LOD's that's the real pain and takes time. I would imagine that Kevin moved on to other models and that this one is still "on the shelf" waiting to be finished at some point.
You'll notice that the last post in that thread was from Feb of 2008 so it's been a while but Kevin will chime in here at some point and give you the official status of this one.
