This kit represents the launch vehicle for the Mars-1 probe: the first Mars flyby in 1963. The resin parts are solid with crisply molded details, finely engraved panel lines and a smooth surface finish. All parts need to be removed from their pour plugs. The instructions show the main core stage as a single part, but it has been cast as two parts in my kit. It's pretty obvious how to join them together, though. The engine bells are nicely hollowed out. There is some flash around the more delicate parts, such as the interstage lattice and booster braces that will need to be carefully removed. Extra parts for the braces and some of the photoetched parts are included. Also included in the kit is a set of the R-7 stencils. The instructions consist of a short program history, a multi-step graphical assembly guide with detail insets, and a painting and decaling guide.
