There's more than one market for a good 3-d mesh. If you still have the rights to the model, then you might consider putting it up on Turbo Squid or 3dDaz.
Small wonder that developers keep their future plans a secret.
The cancellation of a project is always sad news.
Problem is, thats exactly what has happened here, Aerosoft previewed back in Feb I think, I suppose they thought, that the announcement that the A-10 was being redone and some (admittedly) beta shots would suffice, clearly not and thats not held against the other two A-10s at all, just a very visual lesson in the facts of FS life.
Suffice to say I doubt they will yield a second time

.
I suppose if it'd cracked on it'd be a lot closer to completion, but a race was never envisaged and the rush rush work flow I've seen in the past has just shown that it produces one thing for certain, errors, one objective here was to avoid that stigma as much as possible, each bit was made right and remade if required before moving on to the next.
To preview or not, to let slip or not has been the bane of commercial work for as long as I've been in the game (10 and more years), on the one hand it signals to other developers what you have planned, conversely it also shows your hand and in the past others have rushed to compete and be first and steal the thunder.
The one downside that seemed to show its head with previews was vaporware, items would appear and would cause others to yield and move on, sometimes these previews were shown to do just that, other times the project became still born for any number of reasons you can imagine, the end result was, you just never knew if the preview was valid or a feint.
The other tack is to say nothing at all and run the risk of one or two appearing out of the woodwork either just before you have finished or just after.
I do have the rights to the model, though to let it into the FS market place would be bad form and a rub on Aerosoft which I'm not prepared to risk. To go to somewhere else will require the cockpit to be completed and texturing, all valuable time lost from the new project, so it'll get stored, the mesh has enough fidelity to last a good couple of years in its present form, maybe then it'll emerge in some guise or another.
