The resin parts are beautifully cast with crisp details and finely engraved panel lines. The main parts are solid with the exception of the rocket nozzles which are nicely hollowed out. There is some flash on the interstage truss and all parts need to be removed from their pour plugs. There are no visible airholes in my parts. Extra parts are included for the more delicate items, such as the vernier engine nozzles and cross braces. The plastic rod is to be cut and added to the launch vehicle for additional details. The instruction sheet consists of a short program history, detailed graphical assembly steps and a painting and decaling guide. Decals are chosen when you order the kit. Decals are available for eleven different missions. Along with the mission specific decals, a set of R-7 stencils is provided.
