same as basebar (

DISCUS STABILITY SYSTEMS
Several design features of the Discus determine the glider's degree of stability in pitch:
- The combination of wing sweep and spanwise twist.
- Reflex in the root section.
- Reflex support bridles.
- Outboard sprogs, and the height at which they and the transverse battens support the trailing edge.
- The shape of the preformed battens and the internal fabric ribs, and adjustment of the internal velcro attachments,
which define the airfoil.
- The setting of the tip wands.
Correct attachment and proper adjustment of the outboard sprogs are critical to providing adequate stability at low angles
of attack, particularly those below the normal operating range.
