LINDBERGH AND THE ENGINEERING OF HIS PERSONAL SPORT PLANE, THE M12 MOHAWK
Ten years after making the first solo nonstop transatlantic flight, Lindbergh monitors construction and modification of a specially designed aircraft, the M12 Mohawk, built for him by F.G. Miles of Phillips & Powis Aircraft, Ltd. The prototype featured an American Menasco engine that gave it a cruising speed of 170 mph and a range of up to 1400 miles. On April 13, 1937, Lindbergh reports the aircraft is performing well but describes problems with the magneto shaft and the push-rod. He also suggests modifications, including an enclosure on the engine "because of the sand and dust we encountered along our route to India." On September 2, Lindbergh responds to Anderson, a company engineer, concerning a request of Mr. Menasco: "I have received a letter from Mr. Menasco, saying that he has asked you to obtain a copy of 'North to the Orient' and one of 'We' in London so that my wife and I can autograph them for his two boys." Lindbergh will send a copy of &INorth to the Orient, but may not be able to locate a copy of We. Concerning his plane, he writes: "The Mohawk is now at Lympne [an English airfield]. I may make another flight to France within the next few days. If not I will take the plane to Reading. What is the present status of the controllable pitch propeller?" On September 27, Lindbergh inquires about "the crack which you located in the mounting ledge of my engine. I am glad that you will be able to have the old engine installed in time for our trip to the Continent. Have you formed an opinion as to the cause of the crack? Is there any sign of a flaw in the casting, or do you feel that this might be due to the type of engine mounting in the Mohawk?..."
In the next few years, Lindbergh and Anne Morrow Lindbergh made frequent trips to destinations around Europe in the Mohawk, which sported a distinctive orange and black color scheme. (3)
