The Kreider-Reisner KR-21 series began in 1928 as a 2-seat parasol monoplane. Later, the KR-21B was developed as a biplane trainer that was easy to fly for beginners but was also aerobatic in the hands of a more experienced pilot. Unfortunately, due to the onset of the depression few were built. Then in 1929, Fairchild took over Kreider-Reisner and eventually built three KR-21B’s and converted 2 KR-21A monoplanes.
The KR-21B had a wingspan of 27-ft. (top) and 24-ft. (bottom), an overall length of 22-ft. 7-inches. Power was provided by a 125 hp Kinner B5 (R-440) 372 cubic inch 5-cylinder radial engine. The KR-21 had a cruise speed of 98 mph, with a top speed of 123 mph. The climb rate was a very respectable 755-fpm, with a service ceiling of 15,000 ft. and a range of 350 miles.
