Hello Alistair. I considered to purchase Garry Sunderland plans two years before. At the end I decided to make own plans according to Windsock datafiles and Lagorett drawings. The reason was that I prefer EP models, so I decided to make it lightweight. At the present time I finished the airframe basically. In the near future I plan to focuse on more scale details like machine gun ring, engine dummy and armmament.
It is true that Albatros CIII at 1/4 scale is rare occurrence.
Best regards Vladimir.
