Notes: -
Some Oly 2b gliders, it is believed those with a double tailplane fixing, originally had a VNE of 120 knots, some may also have had a VRA of 80 knots. In 2004 the BGA Technical Committee decided to standardise all models at 110 knots VNE and 65 knots VRA.
The longitudinal datum is 200mm forward of the rear face of frame 10. BGA data has previously quoted the front face in error.
Elliotts production started in 1947 with the Oly 1 (wooden skid U/C), Oly 2 (wheel and skid) and Oly 3 (jettisonable U/C). From production number EON/O/107 the Oly 2b was produced with various mods, including the double tailplane fixing to minimise the risk of ground handling damage. About 150 Olys were produced in total.
