History
Design and construction began in March 1922, as the M.F.4 pusher trainer was outdated. The first flight took place on 30 January 1923, flown by First Lieutenant Finn Lutzow-Holm.
Variants
The M.F.7 was first powered by a 160 hp Sunbeam engine, later replaced by 160 hp Mercedes engines. Two were built.
Where you'll see it
It was a temporary solution until a better trainer was designed. The first aircraft entered service with the Navy Air Service flying school on 19 September 1923 and it was retired in 1931. Experience with it led to the M.F.8.
