Makes you wonder it all that time why there hasn't been a better

a new standard glass glider and therefore not economic to produce?

The majority of new gliders being shipped into the US are motorgliders: I WOULD NOT want to fly a non-flapped (standard class) motorglider. Furthermore, the slight cost savings eliminating flaps yields is infinitesimal compared to the total cost of the glider (ask me how I know).
