I am about to begin building an Albatross D-XI from a set of plans that came from a 1949 issue of Model Airpane News. This is a pretty rare bird ( I think only two were built). I have only seen 2 photos of the actual airplane, and I have no info on how it was finished. If anyone out there can share any info on this guy, it would be greatly appreciated.
Windsock datafiles has an excellent book called "Albatros Experiments". There is a section on the DXI with plans. Jager made an excellent model of the DXII and it was very similar to the DXI (basically an engine change) in 1/48. It will eventually be re-released. I hope this helps.
