Design and development

A prototype was constructed in 1930–31 and made its maiden flight on 20 March 1931. The aircraft was, however, under-powered, and the flight characteristics were poor. Suggestions for improvements were made and the engine was replaced by a higher-powered one. The aircraft was damaged in 1933, but was never repaired.[1]

gollark: You are like the vector **p** = **i** + 4**j**.
gollark: Perhaps I'm secretly raging inside. Perhaps I do not actually care and am mostly busy solving some vector-related questions.
gollark: Oh, you do antimemetic proofs? Neat. Guess that's settled.
gollark: Also, 🐝 you.
gollark: Please post a valid apiomathematical proof.
