The Aachen "KF" light airplane (single-seat high-wing monoplane) designed by Kemperer and built by Aachener Segelflugzeugbau GmbH., is a thick-wing monoplane with a central wing length rigidly braced to the fuselage.   The outer lengths of the wings are entirely cantilever with a pronounced sweepback of the leading edge at the tips-
The fuselage is of rectangular section with an inverted vee-shaped deck.   The cockpit is situated under the wing, at which point the deck is omitted.
The landing gear consists of two streamlined outwardly inclined struts which project from the bottom of the fuselage with the wheels sprung from their ends-
The fin and rudder are unusual in their backwardly inclined position.
The airplane is credited with an initial climb rate of 60 m (200 ft.) per minute, and a maximum speed of 46 M-P-H-
