| Contemporary with the P.W.S.10, a less
complicated version with a 179kW Gnome-Rhone Titan engine was designed
specifically for use as a single-seat
fighter trainer. Designated
P.W.S.11, this did not progress beyond
the prototype stage, but a two-seat intermediate-
trainer project designated
P.W.S.12 was developed from it, its
biplane configuration resulting from little
more than the addition of a new lower
wing to the existing airframe. However,
the first two P.W.S.12 prototypes, flown
in November 1929, had reduced-span
staggered biplane wings and introduced
a 164kW Skoda-built version of
the Wright J-5 Whirlwind radial engine.
Successful testing led to an order for
production P.W.S.12s, but a requested
change from wooden to steel-tube fuselage
structure, plus the incorporation of
some improvements, resulted in this aircraft
being redesignated P.W.S.14 at a
later stage.
