The resin parts are solid, with the exception of the nicely hollowed out main engine nozzle. The parts are molded with crisp details, finely engraved panel lines, a smooth surface finish and no visible air holes. All parts are still attached to their pour plugs. Decals are provided to depict the launch vehicle for either Discoverer XVIII or Corona 41. The instructions include a short program history, an exploded assembly drawing and multi-view painting and decaling guides.
