Design
In 1924 Villiers had had some success with their Villiers II or Type 2amC2, a two seat shipboard fighter with a boat-like fuselage underside which enabled it to put down on the sea in an emergency. The 1926 single seat Type 8amC1 had the same ability.
It had a rectangular plan, parasol wing braced from the lower fuselage with pairs of parallel struts on each side which met the wing at about two-thirds span. About halfway up these struts lighter jury struts ran to the edge of the wing centre section, meeting short cabane struts from the upper fuselage. The wing had a wooden structure with fabric covering and carried full span ailerons.
The Type VIII's fuselage also had a wooden structure but was plywood covered. It had an unstepped planing bottom and was divided into several watertight compartments to keep the aircraft afloat even with fuselage damage. In an emergency over water the land undercarriage was jettisoned and the aircraft stabilised by a planing float on each side, mounted on the wing struts at the lower end of the jury struts. The land wheels were on a single axle, sprung from the cross-member of a frame formed by longitudinal V-struts from the lower fuselage and a transverse V from the same points to the centre of the cross-member. The pilot's open cockpit was under a wing trailing edge cut-out and was provided with a small, streamlined head-rest. He controlled two fixed 7.7 mm (0.303 in) synchronised machine guns firing through the propeller disc.
Its tail unit was conventional, with a broad chord, clipped triangular tailplane mounted on top of the fuselage and fitted with separate, round edged, balanced elevators. The triangular fin and its full, rounded unbalanced rudder were also broad, the rudder extending down to the keel and operated in a gap between the elevators.
Operational history
The exact date of the Type VIII's first flight is not known but it was evaluated in military trials late in 1926 at Saint-Raphaël as the Vil 8amC1. The military preferred its competitor, the Lévy-Biche LB 2amC1, and development of the Type VIII ended.
