BUT the idea that we have the airframe is false because the Stukas modeling is old and they would have to update it before they could modify it to the G model.
I believe it had longer wingtips, ailerons, etc, as well. It would have some differences, probably as many as exist between the A6M2 and the A6M3 (not many, but some to at least make note of)
wasn't that the d-5/g-2 version that had the structural changes?
I wouldn't say "structural" -- because the R-2 had "structural" changes to reinforce it allowing it to pull more Gs, but it looked the same. I would say "external" -- and yes you are right. That would be the most likely candidate, if this bird were added to the game, no? The handful of converted D-3 models were not the most common. The G-2 was most common, if I recall, with 200-300 made. I think (could be wrong) only a couple dozen were converted D models.
