Hi Dene, Just as well I said I would check :) Here are the _correct_ figures for the Comper Swift fitted with the Pobjoy R seven cylinder radial engine (as modelled) Cruise: 120 mph (104.2 kt) Max: 140 mph (121.6 kt) Landing/Stall 40 mph (34 kt) Not sure exactly what is meant by the Landing/Stall speed :s but in a flight report from 1931 the pilot said "The elevators give a much better impression of effectiveness down to about 45 mph - which was the slowest to which I dared stall" - here he was comparing a model where the cut-out in the wing trailing edge for the cockpit had been smoothed with an earlier model where it was more angular. The same pilot went on to say that he felt happiest landing at 55 mph (47.8 kt) HTH LeeE _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
