[2] After the relative success of the FVA-1 Schwatze Düvel and FVA-2 Blaue Maus, Wolfgang Klemperer designed and built the canard FVA-3 Ente.
Using similar construction methods to the earlier gliders, Klemperer built the FVA-3 from wood with fabric covering, the thick cantilevered mainplane supporting a wide fuselage, extending forwards from the centre section, enclosing the side-by side cockpit forward of the mainplane and supporting the forward plane which was mounted on spherical bearings to provide control in pitch and yaw.
[2] The control system used the foreplane and 1.2 m (3 ft 11 in) span slotted ailerons at the tips of the mainplane.
Fore-and-aft movement of the stick altered the angle of attack of the whole foreplane, raising or lowering the nose.
[2] Flight tests revealed a poor weight distribution, requiring the aircraft to be dismantled and the centre of gravity adjusted.
