with 50 h.p. Gnome engine, was notable chiefly for its large wheels
and jointed fuselage, which enabled the machine to be taken down for
transport. The Savary biplane took part in the French Military Trials,
1911. It had a four-cylinder Labor aviation motor. Notable features are
twin chain-driven propellers, rudders between the main planes, the broad
wheel-base and the position of the pilot. The Paulhan triplane, which
also figured in the French Military Trials, was a development of the
Paulhan folding biplane. It had a 70 h.p. Renault engine. For practical
purposes it was a failure. The R.E.P. biplane, with 60 h.p. R.E.P.
engine, was a development of the famous R.E.P. monoplanes. Its spring
chassis, with sliding joints, marked an advance. Like the monoplanes,
it was built largely of steel.

In 1912 came the first really successful Handley-Page monoplane, with
50 h.p. Gnome engine. The Short monoplane, was built generally on
Bleriot lines. Its chassis was an original feature. The Coventry
Ordnance biplane was a two-seater tractor built for the British Military
Trials. It had a 100 h.p. 14-cylinder Gnome engine, with propeller
geared down through a chain drive. The machine was an interesting
experiment, but not an unqualified success. The Moreau "Aerostable,"
fitted with a 50 h.p. Gnome, was a French attempt to obtain automatic
stability, but it only operated longitudinally. The pilot's nacelle was
pivoted under the main planes, wires were attached to the control
members so that the movements of the nacelle in its efforts to keep a
level keel brought them into operation. The Mersey monoplane, an entrant
for the British Military Trials, was designed to present a clear field
of view and fire. The 45 h.p. Isaacson engine was connected by a shaft
to a propeller mounted behind the nacelle on the top tail boom. It was a
promising experiment, but came to grief. The Radley-Moorhouse monoplane
was a sporting type machine on Bleriot lines, with 50 h.p. Gnome engine.
It was notable for its streamlined body and disc wheels.
