Slingsby Type 31 TX Mk 3

This glider, for many years alongside the Slingsby Type 21b Sedbergh forming the backbone of the biggest gliding club in the world (Air Cadets) is the subject of a thread on both Pprune and Flyer Forums.
I'm sure many of you, like me, flew their first ever solo flights in one of these so if you're on one of the other forums, please contribute.

Too late to edit, but if you can find a copy of 'Pilot' magazine for Feb 2019 still in the newsagents, there's an air test of the Mk 3 on p24 onwards.
As for 'cadets' efforts to break them' unlike todays 'glass ships' they were made of wood and fabric and hence easily repairable.
There is even a suggestion in Pprune that maybe production could be re-opened (and I support this suggestion) using more modern materials as the aircraft was eminently sutiable for purpose ie getting as many cadets airborne and flying solo as possible, whereas in todays civilian gliding clubs, the emphasis is on soaring flights for which you do need a more modern design.
