Two people can easily disassemble the Skylark. By removing three bolts, the horizontal tail surfaces can be folded up against the fin. Each wing can be detached by removing only four bolts. The Skylark wing profile was designed by NASA using technology specially for use in slow-flying aircraft. Features include low drag in the range of useful airspeeds, low stall speed, and mild stall characteristics (which are fully exploited by the forward-swept wing to produce a “spinproof” design). Aluminium sheet, extruded tubes and angles, all of general-aviation proven 2024 alloy are used throughout. Airtech uses modern adhesive bonding technology, along with blind and solid rivets. High-strength PVC foam, stamped aluminum ribs, silky-smooth Teflon bellcrank bearings, aluminum pushrods with spherical couplings, “Ceconite 7600 Process” aircraft fabric, precision molded fiberglass fairings, molded plexiglas windscreen all combine to satisfy the most demanding aviators. The standard airspeed indicator, alti-meter, tachometer and toe-operated disk brakes are as comforting to the pilot as the contoured seat designed for those up to 6 feet, 6 inches, with “stick-and-rudder” controls.
The Skylark uses the Konig SD-570 four-cylinder radial. Using a 2.8:1 reduction drive, the Skylark’s engine turns its 72-inch propeller at only 1500 rpm during takeoff; the result is exceptional static thrust and the vir-tual elimination of propeller noise.
