The Kinner C-7 Envoy
was a 1930s American
four-seat cabin monoplane built by Kinner Airplane & Motor Corporation
Design and development
was a four-seat version of the Sportwing
. It had low wings fitted with wire bracing from fuselage points just below the cabin windows. The fixed tailwheel undercarriage was fitted with streamlined spats. The low-set tailplane was braced by wires from the middle of the fin.
Four civil examples were completed from 1934. These were fitted with a 300 h.p. Kinner C-7 engine. The civil aircraft were followed in 1936 by three aircraft for the United States Navy
(USN) for use in communications work and designated XRK-1
. The USN machines served until the early years of World War Two
. The Imperial Japanese Navy
evaluated a single example as the LXK
When delivered the USN examples were fitted with a 340 h.p. Kinner R-1044-2 engine, but one example used for VIP transport was later fitted with a 400 h.p. Pratt & Whitney R-985
-38 radial engine.
The C-7 was the last of Kinner's production models.
