fairing and three seats, one behind the other. The fuse-
lage shape is aerodynamically superior to the BA 39S, ow-
ing to the round section of plywood in front (to conform
to the Fiat radial engine) and its oval shape in the rear.
The tail surfaces are of wood with fabric covering, with
the exception of the rudder which is of welded steel tubk
ing. The landing gear is similar to that on the 39S.
Bergamo PS 1.- Designed by the Cantieri Aeronautici
Bergamaschi as a four-place, low-wing, cabin monoplane
(figs. 9a and 9b), the wing structure is of metal, of the
single-spar type and fitted with slots; spar truss and
ribs are of welded steel tubes. The fuselage and the tail
surfaces are also of steel tubes covered with fabric. The
landing gear is partially retractable rearward into the
D.H. "Puss Moth". - This is a three-place, braced,
high-wing cabin monoplane of well-known design, which was
converted to conform to the rules of the race. It was
fitted with full-span slots and flaps next to the fuselage.
Power plants.- The regulations stipulated no limita-
tions as to performance, displacement, etc. On the other
hand, the designer was forced to select an engine of max-
imum output in order to remain within the prescribed limit
of 560 kg (1,234.59 lb.) tare weight. Poland was the only
country which concentrated on a special engine design,
since it naturally desired to provide a power plant of
national make. For the rest, the airplane designers
should have had no special difficulties in selecting a
suitable engine from among those available.
ArgusAs 17.- This is a development of the well-known
As 8 and As 8R to a 6-cylinder engine.
Hirth HM 8U.- This is a modern version of the HM 150
and was much preferred by the German constructors because
of its compactness and high performance.
