THIRD of British turboprop-powered airliners to fly, theMarathon 2 is a Mamba-powered experimental versionof the 20-seater feederliner now in production at the Woodley works of Handley Page (Reading), Ltd. As these two new Flight photographs show, the two Arm- strong Siddeley turboprops have replaced four Gipsy Queen piston-engines of the original version. Small outboard '' nacelles'' remain to tair-oif the operating mechanism of the Miles retractable, auxiliary-aerofoil flaps. Despite the changed pattern of flow over the tail unii involved by the new power installation, no re-design of the surfaces has been made. The Mamba tail-pipes pass over the wing and the small jet efflux has had no noticeable effect on handling or upon the skin. i;, From the Mambas the Marathon 2 receives a total power « approximately 2,000 h.p.—an increase of over 600 h.p. on the power of the Mark I'S four 345 h.p. Gipsy Queens. Operating at their most economical—and almost their maximum—r.p.m., the turboprops will confer a cruising speed of over 250 m.p.h. Carrying 18 passengers, or 4,370 lb of freight, the Mamba Marathon has the very useful range of 770 miles. Comment was made .recently in Flight on the aircraft's impressive flying characteristics, notably on take-off and climb.
