A separate yaw control is not provided. Like other weight shift aircraft, yaw is provided
from the secondary effect of banking.
CORSET:
The CORSET allows the pilot to adjust both the trim speed and the configuration of the
wing (twist and reflex) according to speed. At low speeds, the twist increases, the reflex
of the central profile decreases, thus affording better handling and the lowest stall speed.
At high speeds, cruising stability is given preference, as is aerodynamic efficiency. Its
operation is transparent to the pilot and may be compared to that of the trim in a classical
pitch system.
To increase trim speed, push and turn the control lever clockwise. When you stop turning,
and release the lever, the reel is blocked. Maximum speed configuration is attained when
the fine cord reaches the back end of the opening, next to the “bird at high speed” icon
located on the base of the control lever (Figure 5-3). To decrease trim speed, push and
turn the control lever counterclockwise. Minimum speed is attained when the fine cord
reaches the front end of the opening, next to the “bird at low speed” icon. Do not try to
turn the lever beyond this position in order not to effect an inverted reeling of the fine
cord. For takeoff and landing approach, it is recommended to set the CORSET in the
slow speed configuration.
In very turbulent conditions, the CORSET should be adjusted to the green swathes at the
center of the color chart located on the base of the control lever (avoiding the yellow
swathes at the ends of the chart), in order to limit use of high and low speeds to levels
adapted to guarantee the best maneuverability of the wing.
On the ground, the CORSET control lever should be left in the slow position to limit
tension on the sail.
