The Kreider-Reisner KR-21-A was a 1928 American two-seat monoplane. They were designed and built by the Kreider-Reisner Aircraft Company of Hagerstown, Maryland.[1] Fairchild Aircraft took over Kreider-Reisner in 1929 and continued to build them, as the Fairchild KR-21, later the Fairchild 21.[2][3]
Design and development
The KR-21-A was a low-wing braced monoplane with two open tandem cockpits and powered by an 80 hp (60 kW) Armstrong Siddeley Genet radial piston engine.[2] It was of mixed construction and had a fixed tailwheel landing gear and was fitted with dual controls.[2]
The KR-21-B was a more powerful biplane development, using a 125 bhp Kinner B-5 engine.[1] Five were produced, three built as -B models and two converted from the -A.
At least three, most of the production, survive today
The KR-21 would in turn form the basis of the KR-22 parasol-wing monoplane design.[6]
