L.Opdyke French Aeroplanes Before the Great War (Schiffer)
Deleted by request of (c)Schiffer Publishing
Gregoire-Gyp 1910: One of these monoplanes was a cross between the Hanriot (undercarriage) and the Antoinette (wing, tail, long covered fuselage, side-mounted control wheels, tail surfaces). It sat tail-high on its wheels and long forward skids, a very graceful machine. Another, perhaps a version of this one, had a slightly heavier-looking fuselage and modified rudder, and sat back on its tailskid. And still another, powered with a 40 hp Gregoire-Gyp engine, was a still closer copy of the Antoinette, with a simplified V-leg undercarriage and Bleriot-style pylon. The control wheels were set halfway down outside the fuselage sides.

THE SECOND OLYMPIA AERO SHOW.
FRENCH-BUILT monoplane of a type intermediate between the Antoinette and Bleriot. The main wings are of 34-ft. span, and are warped for steering and securing; lateral stability. Control is by two hand-wheels, one on each side of the driver, that on the right warping the wings, while the one on the left operates the horizontal rudder, the vertical rudder being worked by a foot-bar. The machine is carried on a combined skate-and-wheel frame, the wheels being used to run on the ground for starting purposes, and the skids coming into operation on landing.

MONOPLANE of modified Antoinette type, mounted on a massive but strong and light "A" chassis with ski and wheel attachment. The feature of the power plant is the fitting of a 40-h.p. Gregoire engine upside down. Lubrication is effected by means of a pump forcing castor oil direct to the crank-shaft bearings. It is claimed that with proper fitting pistons there is no greater liability to soot the plugs through an excess of oil passing the pistons than occurs with the engine in an upright position. Wing warping, with tail and elevator control, is accomplished by side wheels and pedals, as on an Antoinette monoplane.
