Control
The Paresev was controlled by moving the tensionally hung pilot's and fuselage's mass relative to the position of the wing. This mass-shifting was effected by tilting the wing from side to side and fore and aft by using a control stick in front of the pilot that descended from the wing above. Another version translated the same weight-shift control via cables. As the Paresev was towed in a kite mode, it usually rose from the ground at about 46 mph (74 km/h) and had a maximum air speed of about 65 mph (105 km/h). The Paresev control pendulum weight-shift control system was presaged by a published patent, an early use of the hung pilot behind a cable-stayed triangle control bar in 1908 in the territory of Breslau, and then also by control wing of George Spratt in the 1920s.

Famous quotes containing the word control:
“All industries are brought under the control of such people [film producers] by Capitalism. If the capitalists let themselves be seduced from their pursuit of profits to the enchantments of art, they would be bankrupt before they knew where they were. You cannot combine the pursuit of money with the pursuit of art.”
—George Bernard Shaw (1856–1950)
“The preservation of life seems to be rather a slogan than a genuine goal of the anti-abortion forces; what they want is control. Control over behavior: power over women. Women in the anti-choice movement want to share in male power over women, and do so by denying their own womanhood, their own rights and responsibilities.”
—Ursula K. Le Guin (b. 1929)
“Imagine believing in the control of inflation by curbing the money supply! That is like deciding to stop your dog fouling the sidewalk by plugging up its rear end. It is highly unlikely to succeed, but if it does it kills the hound.”
—Michael D. Stephens. “On Sinai, There’s No Economics,” New York Times (Nov. 13, 1981)
