- Wings: spar and shell of foam / carbon reinforced plastic sandwich
- Ailerons: synthetic foam / aramid reinforced plastic sandwich. Ailerons extend over fully half the glider span.
- Horizontal stabilizer: sparless sandwich of carbon reinforced plastic
- Elevator: carbon/aramid reinforced plastic
- Automatic connections for ailerons, airbrakes, elevator and water ballast valves
- Integral Teflon and PET film seals on all control surface gaps.
- Water ballast system: one unvented ballast bag per wing located before the spar, valve and dumping orifice on the lower wing shell by the wing root. Glass reinforced ballast tank installed in the tail fin for correction of centre of gravity shifts due to wing ballast.
