NVI F.K.34

The NVI F.K.34 was a three-seat reconnaissance floatplane built in the Netherlands in 1925 as a private venture in the hope of a Dutch Naval Aviation Service order; two accidents during testing meant that it did not go into production.

Here, the tailplane was located on top of the fuselage and also braced on each side with [pairs of parallel struts; its elevators had rounded tips which served as horn balances.

The pilot sat in an open cockpit under the wing trailing edge where there was a rectangular cut-out for enhanced visibility.

In the nose the three cylinder banks of the 520 hp (387 kW) W-12 Hispano-Suiza 12G engine were neatly enclosed in a drum and dome-like cowling.

After this the FK.34 was extensively tested by the MLD (the Marine Luchtvaart Dienst or Dutch Naval Aviation Service), to whom NVI looked for an order.
