Design

The VSO 10 is a mixed-construction glider with wooden and steel tube structural members, aluminium alloy rear fuselage and glass-fibre sandwich skins. The wings are shoulder-mounted and the tailplane is mounted on top of the integral fin. Conventional control surfaces include all-wooden slotted ailerons, all-metal DFS airbrakes on the upper and lower surfaces of the wing and fabric-covered all-metal elevators and rudder. The undercarriage in the Standard Class aircraft is a manually retractable rubber-sprung monowheel with a drum brake, (non-retractable in the Club-Class aircraft), with a rubber-mounted steel skid under the tail. The pilot is accommodated in a fully reclined seat under a two-piece canopy. Provision is made for of water ballast to optimise cross-country performance in strong lift conditions.
