Design and development
The KK-1e was one of the first fibreglass sailplanes produced, first flying in 1964.[1][2]
The KK-1e has a 15.0 m (49.2 ft) span wing, with a single spar. The wing employs a NACA 63-618 airfoil at the wing root, changing to a NACA 63-612 section at the wing tip. The wing features a split terminal velocity trailing edge combination spoiler/dive brake. The landing gear is a fixed monowheel.[1][2][5]
The aircraft was not type certified and the one aircraft imported into the United States was registered with the Federal Aviation Administration in the Experimental - Exhibition/Racing category.[1][2][3]
Operational history
Only one KK-1e was imported into the United States in 1967. As of July 2011 this aircraft was still registered with the FAA to its original owner.[3]
