The German Institute for Sailplane Flight (Deutsche Forschungsalstalt für Segelflug or DFS) promised to meet the RLM's need for an uninterceptable reconnaissance aircraft with this remarkable rocket-powered sailplane, which was a true ancestor of the Lockheed U-2. Shelved from 1940 through early 1943 due to pressure for other work, the 228 was resurrected and two prototypes completed in 1943. The 228 was made almost entirely of wood, with a pressurized metal nose compartment that could be jettisoned in an emergency and recovered by parachute. The mid-fuselage housed rocket propellants (C-Stoff and T-Stoff) and two Zeiss infrared camera. By the time Allied troops reached Griesham, many glide test flights has been made after launches from a specially prepared D0 217 K3, but none under power. Although designed for altitudes approaching 80,000 feet, no glide flight went above the 33,000 feet launch altitude.

Cockpit: 

Wow! What a cockpit HUMA gives you with this model. There are 17 parts in total excluding the pilot figure and most are molded in plastic almost as thin as photoetch. So a word to the wise, use styrene cement sparingly. The cockpit was painted RLM66 with various pressurized bottles and radio equipment paint yellow, blue, and black. The pilot was primed in Khaki and brush painted. Sadly, very, very little can be seen once the cockpit is assemble and closed up under that porthole nose glazing. But look close, you can see Fritz flying his sled :>). The landing skid bay should also be installed with the cockpit before close the fuselage halves, this was painted RLM02. 

Exterior:

Once the cockpit is painted and installed, the exterior is a pretty simple affair consisting of 12 parts discounting the landing skid. The landing skids are nine parts including the main skid, skid bay, and small rear skid. I only used the skid bay, main skid, and the rear skid, so retractable struts and rods were not used for my in-flight model.

 There was much work in contouring the porthole front window, the four small cockpit windows, and the round camera window. They were attached with CNA glue, as I knew I would be doing a lot of sanding. I started with a fairly course 400-grit and wet sanded all until all blended in well. I next worked everything down in varying grits down to 3200-grit. After that, I rescribed the sanded out detail and resanded with 3200-grit. After I cleaned the resanded areas, I polished everything with Meguiar's Mirror Glaze #7, an auto polishing compound. Once to my liking, I switched to Meguiar's Mirror Glaze #3, an auto glazing compound, and further polished everything until the clear parts had clean clear surfaces.

 Clear parts were masked with Bare-metal foil and the surfaces cleaned and prepped with 99% isopropyl alcohol (one can get the 99% isopropyl at the local pharmacy, just ask for it if they do not have it on the shelves).
