The major German manufactures are cooperating with government help to 
investigate means of producing gliders more economically. They are concerned 
about South Africa’s lower labour costs. As Jonkers have produced 100 high 
performance gliders that otherwise might have been produced in Germany, pretty 
understandable. The German manufacturers have until now steadfastly refused to 
incorporate ideas proven successful by other manufacturers. Just think about 
Hotelier fittings and self connecting devices to connect wing functions to the 
fuselage.

It all comes down to money.

Gliding isn't large enough to support the large capital expenditures to 
automate the manufacturing processes and I'm not sure making gliders a fair bit 
cheaper would actually increase sales by all that much as the sport appeals to 
a limited number of people, including a limited number of people who are 
already pilots.

  The German ones I saw were resin and about 7 years ago.

  However, two years in Dubai, I saw keels being machined out of solid
  steel billets inside machines which were large enough to fit a truck
  and other even larger CNC machines being used to machine one piece
  moulds for one-off 60' boats. There were also autoclaves as large as
  factories for cooking the parts.
