The Magister trainer had been
built in many hundreds by 1938,
but Mr Miles felt that he could
produce an even better machine
within similar specification
limits, and proved his theories
with the Trainer M.18, which
flew for the first time in 1939.
Beyond the fact that it was a
tandem two-seat low-wing
monoplane, the M.18 had nothing
in common with the Magister.
The main design considerations
were ease of handling and
serviceability, and these aims
were attained in a high degree,
the machine being most
delightful to fly, with controls
light and positive right down to
the stall.
In the course of extended trials
several variants of the M.18
were tested, with open and
enclosed cockpits, tail-wheel
and tricycle undercarriages, and
with the Gipsy Major and Cirrus
Major engines, the combined
results proving that the machine
was an ideal training type.
After successful official
acceptance trials the M.18 was
ordered for quantity production,
but the order was almost
immediately reversed because the
existing biplane design was in
large-scale manufacture. Then,
in 1942, the machine was again
ordered for production, but
official policy was again
changed and the M.18 was
cancelled once more.
