Notes: -
The Oly 460 was the designation of the prototypes. They had fabric covered rear fuselage tops. The 463 was the production version (which came out in 1963), it has a glass fibre rear fuselage top. The Oly 465 had a thinner wing and strengthened spar. Only 2 were made (for the 1965 world championships).
All the above data applies to the 460 & 463. Some may apply to the 465.
