There is a drawback to using the D1A as an He 50 or He 66. So far I have found only one photo of a Luftwaffe He 50 with an engine cowling:
http://www.airwar.ru/image/idop/spyww2/he50/he50-4.jpgNote that the cowl ring on this aircraft, D-IMOE, is very much like the cowling on Giotto's D1A2. On the other hand, the D1A2 had wheel spats, and D-IMOE did not.
Giotto's D1A1 has a much narrower cowling, but the model is otherwise essentially identical to the He 50s in every other photo I have. Here's another link to the same website, and a selection of half-a-dozen different photos. I've also seen photos, taken at frontline airfields, of He 50s in camouflage, but, naturally, these are all monochrome photos, and the quality is fairly poor.
http://www.airwar.ru/enc/spyww2/he50.htmlI could live with an He 50 with the narrow cowl ring. Frankly, I'm hoping that it will be possible for someone to produce Luftwaffe skins for the D1A1 or D1A2 (He 66?). I must say, however, that removing the cowl ring from Giotto's D1A1 would result in a near-perfect Luftwaffe version of the He 50. This, however, is far beyond my ability. In any event, even if I could somehow eliminate the cowling, I would of course want to consult with Giotto on this.
Thank you, VonWaffen, for having a look at this, and a word on the subject.
