Waco AVN / ZVN / UC-72J / UC-72L
 
Waco-VN-01
 
The Waco N series is a range of 1930s American-built cabin biplanes with a fixed tricycle undercarriage introduced in 1937. It was based on the Waco C series five-seat Custom Cabin Waco with that model's curved pointed wings, but with a fixed tricycle undercarriage and a modified tail with a lower rudder extension to give increased side area. The Waco N was fitted with flaps on all four wings to improve the aircraft's landing characteristics.
 

The prototype, was designated ZVN-7, with the '7' indicating its year of manufacture (1937), and was powered by the 285 hp (213 kW) Jacobs L-5 engine. Only around 20 examples of the N series were completed, as the AVN-8, and ZVN-8. This included ZVN-9 NC19362, NC19372, NC19374, and NC19399. NC19399 was impressed by USAAF as UC-72L.

 
Waco-VN-02
 
A few were impressed by the USAAC during the Second World War as the UC-72J and UC-72L. One AVN-8 was used by the Royal Aircraft Establishment at Farnborough, Hampshire, for trials with tricycle landing gear.
