Two model 465s, with slimmer, slightly longer fuselages made possible by a semi-reclining pilot's position, were built for the 1965 World Gliding Championships.

All have plywood DFS type airbrakes extending above and below the wings; standard class gliders do not carry flaps.

The tailplane is a cantilever structure, mounted on top of the fuselage, folding upwards for transport and carrying conventional split elevators with a starboard trim tab on the prototypes and production 463s.

[2][3] The fuselage is a flat-sided Warren girder structure, plywood covered apart from the curved glass fibre rear decking.

It was followed by the Type B with aspect ratio of 18 and an all-up weight of 630 lb (286 kg), the values adopted for production machines.

[4] Both the EoN 465s competed in the 1965 World Gliding Championships held in the UK at South Cerney but performed poorly, placed 9th and 41st out of a field of 45 in the Standard Class.

[8] Most of the 460 series aircraft flew with clubs and private owners in the UK, including five used by Royal Air Force Gliding & Soaring Association branches.

Some are still flying, including BGA1296 ("BWE"), which was at the Vintage Glider Club rally held at Tibenham in August 2010.
