Greetings all; Part two is in the works. Kere is a bit of fun on the differences between the Alb. D.V & D.Va.
There was a lot of difference and the wings were not interchangable though they were the same dimmensions. The main difference lay in the routing of the aileron control cables.
In the D.V they went up from the cockpit up between the guns , through the top wing to the ailerons and were actuated by bell crank control horns that had external shrouds. The engine was the late production 170hp Mercedes D.IIIa.
In the D.Va they went through the lower fuselage sides through the lower wing to the area behind the lower end of the interplane Vee struts and exited upward to a cutout in the wing and a control bar extending from the aileron. The engine was the 180hp Mercedes D.IIIaü. Here is an image from Mark Miller's renderings of a D.Va wing. Used with his permission of course. (Another WNW artist by the way.)
The control column was different in its cable attachment points and the height of the top wing was nominally different as well.
