FineScale Modeler reviews the 1/32 scale plastic model aircraft kit. Built in a bewildering array of model numbers predicated on engine type, power, and wing layout, Nieuport fighters of one type or another served throughout World War I. Many were used by air arms other than the French including the Russian Air Service, the subject of Copper State Models Nieuport XXI kit. Included are markings for four Russian Nieuports, one in camouflage and three in silver. Interestingly, two of the four are armed with Le Prieur rockets mounted to the interplane struts. A photo-etched metal (PE) fret provides seat belts, miscellaneous details, and metal panels to protect the wings from the rockets’ red glare.
