Comment:
The 17 m. Kestrel features camber-changing flaps
that operate in conjunction with the ailerons,
airbrakes, drogue chute, water ballast and
retractable gear. The fuselage is a fiberglass
monocoque (not sandwich) for greater resilience
and pilot protection. The cockpit has room
enough for a 198 cm / 6 ft pilot and features a
control stick that slides fore and aft (rather
than rotating) to reduce likelihood of pilot-
induced oscillations and which has a press-to-
trim-push-button trimmer. It has a nose and a
center of gravity release. Goran Ax won the
second Smirnoff Transcontinental Sailplane Race
in a Kestrel in 1973. Sue Martin of Australia
gained both the womens world 100 km speed record
( 113.2 kph / 70.36 mph ) and 300 km triangle
speed record (114.4 kph/ 71.11 mph). As well as
building the 17 m. model under license, Slingsby
of Great Britain developed a 19 m. version which
first flew in 1971 incorporating a drag reducing
wing root fillet and an anti-balance tab on the
elevator. |
