Comment:
In 1938 Laister completed a sleek gull-wing sailplane, which was referred to as the Lawrence Tech Sailplane after its sponsor. Repainted red, white and blue and renamed the ムYankee Doodleメ it competed in a 1939 aerobatic competition at the Paris airshow. With the need for military trainers on the outbreak of World War II, Laister designed the two-place Yankee Doodle 2 from the original with straight wings and automatic control hook-ups. Under the sponsorship of John Kauffmann, a St. Louis businessman, simplified versions were produced in quantity as TG-4Aメs for the USAAC in 1942-43. A flat-top Version with increased performance also has an ATC. A ムbunnynoseメ LK, flown by Harold Hutchinson, held the national multiplace goal record of 399 km/ 248 miles from 1956 to 1967. The Vintage Sailplane Association has copies of the military manuals, color scheme drawings and paint chips available. One LK-10A belongs to the National Soaring Museum. ATC
