Just a suggestion but in doing some digging I noticed a handful of T21s were self built and felt Cadets would get far more value from gliding if they actually built a few of their own aircraft under supervision.
Value coming from team skills, tool skills, patience, persistence and a better understanding of aero engineering and aerodynamics.
Sadly I could not find a suitable training glider kit and I assume certification cost and complexity plus liability issues have stopped this.
So has anyone got the plans for a T21, a few aluminium struts, plywood and canvass? Would the BGA, MOD and MAA object or co operate?
