The Kreider-Reisner Midget was an American light racing monoplane, the first aircraft designed by the Kreider-Reisner Aircraft Company of Hagerstown, Maryland.[1]

Design and development

The Midget was a low-wing racing monoplane powered by a 29 hp (22 kW) Wright-Morehouse engine which first flew in 1926.[2] Designed by Charles W Meyers and engineered by Frederick E. Seiler, Jr.,[3] it should not be confused with the Meyers Midget a high-wing monoplane built in the Kreider-Reisner factory for Meyers in the same year.[2] The Midget won the Scientific American Trophy at the 1926 Nationals.[2]
