The Kreider-Reisner KR-21-A is a 1928 American two-seat biplane. It was 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

Designed by Fred Seiler Jr., H.L. Puckett states "over 200 were built in 6 different models."[4]

The KR-21-A was a wire braced biplane with two open tandem cockpits and powered by a 100 hp (60 kW) Kinner K-5 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]
