Comment:
A development of the O-2 but for Open Class
competition, the O-3 featured a longer span of
higher aspect ratio, with trailing-edge
airbrakes and a retractable gear. One was flown
in several Nationals and made a flight of 694
km./ 431 miles. Two O-3ﾒs were built, and both
were subsequently motorized. A two-cylinder, in-
line, two-cycle Yamaha snowmobile engine was
mounted inside the fuselage behind the wing spar
driving a pylon-mounted pusher propeller via
belts. |
