Thank you, Novice--that was one of the exact references I used, but the resulting aircraft in FD wasn't sufficiently detailed enough, meaning I had to find other sources, including a cardboard model of a slightly later model. The main difference lie in the panel lines of the rear fuselage, which I saw no reason why they'd not be present in the earlier model. Most of the line drawings available weren't very detailed, leaving this area blank, which didn't seem accurate.
This is the other reference, but it is a later version, and I don't completely trust the accuracy of it in other regards, so I made a point of limiting how much I actually took from this.
@deankal55: The NEI version is the later one with the retractable landing gear which I plan on doing after I get everything with this version squared away. I likely will leave the specific paint scheme to ALVAMA, or whoever wants to do it. This was originally supposed to be done by ALVAMA, but he suggested I attempt it as a starter project, since it's a comparatively simple aircraft. When I do a fully painted version, it will likely be in the FD AU section. A reminder that the above is still a WIP--I'm a long way from happy with it right now.
