This kit represents the MRPV (Multi Research Payload Vehicle) launch vehicle flown in September 1965. The resin parts are solid, except for the nicely hollowed engine nozzle. The parts are molded with crisp details and finely engraved panel lines. There are no airholes on my parts and all parts are still attached to their pour plugs. You will need to provide a bit of wire or rod for the turbine exhaust supports if you so desire. The instructions consist of a short program history, graphical assembly steps and a four view painting and decaling guide.
