Canard (aeronautics) flown, including the Ambrosini SS.4, Curtiss-Wright XP-55 Ascender and Kyūshū J7W1 "Shinden". These were attempts at using the canard configuration to give advantages in areas such as performance, armament disposition or pilot view, but no production aircraft were completed. The Shinden was ordered into production "off the drawing board" but hostilities ceased before any other than prototypes had flown. Just after the end of World War II in Europe in 1945, what may have been the first canard designed and flown in the Soviet Union appeared as a test aircraft, the lightweight Mikoyan-Gurevich MiG-8 "Utka" (Russian for "duck"). It was
Canard (aeronautics) propeller: "the power-induced flow clean up of the wing trailing edge" increases the wing lift coefficient slope (see above). Conversely, a propeller located ahead of the canard (increasing the lift slope of the canard) has a strong destabilising effect. A highly loaded lifting canard may not have sufficient spare lifting capacity to accommodate large movements of the centre of pressure or of the centre of gravity. Trim may be accomplished in similar manner to a tailless craft, by adjustment of trailing-edge surfaces. In particular, the use of landing flaps on the main wing causes a large trim change. The Saab
