Development and design

The Envoy was designed by N.S. Norway and A. H. Tiltman as a twin-engined development of the Courier. It used the same wooden construction, outer wing panels and retracting main undercarriage.

The Envoy was a twin-engined low-wing cabin monoplane of all-wood construction apart from fabric covered control surfaces. It had a rearward retracting main undercarriage with a fixed tailwheel. The aircraft was built in three series, the Series I was the initial production variant which did not have trailing-edge flaps, seventeen built. Thirteen Series II variants were built with split flaps and the Series III (19-built) was similar but had detailed improvements. Each series of the Envoy was sold with a choice of engines including the Armstrong Siddeley Cheetah V or Armstrong Siddeley Lynx IVC radial engines. These different engines were housed under a variety of cowlings, mostly short chord Townend rings but also wider chord cowlings with and without blisters for cylinder heads.Taylor 1970, pp....
