ROLL/YAW TRIM
Turns in gliders occur when they are asymmetrical. If you have a turn in your glider you should
confirm that the six possible variables outlined at the beginning of this section have been checked.
The following tables outline procedures for adjustments. Adjustments should be made to the glider
in the sequence as listed. The glider should be tuned firstly in the VG off setting and then checked
with the VG ½ and full on.
NOTE: We refer to the fast wing as the wing on the high side of the turn i.e. The right wing is the fast
wing if the wing is turning left and vice versa.

DIFFERENTIAL BATTEN TENSION.
If the turn is mild, then increasing and decreasing the
batten tension on either side can adjust it. If you increase
the tension on the slow side you are effectively putting
more camber in the airfoil therefore creating more lift on
that side.
If you decrease the tension on the fast side you are
decreasing the camber and reducing the amount of lift.
The batten hinge clip can be rotated clockwise to
decrease tension or anti-clockwise to increase tension.
Increase tension on last 3
battens on left hand side
by 1 turn at a time.
Decrease tension on last 3
battens on right hand side
by 1 turn at a time.
Decrease tension on last 3
battens on left hand side by
1 turn at a time.
Increase tension on last 3
battens on right hand side
by 1 turn at a time.

TIP PLUG ADJUSTMENT
The tip plug can be rotated to increase or decrease lift on
either wing. The fast wing should have the tip fitting rotated
upward to increase washout on that side. Requires 5/32” drill
and rivet once rotated
.
Rotate the right hand tip
fitting clockwise if viewed
from the rear of the leading
edge. The tip fitting should
be rotated a maximum of 5
mm. Rotate the left hand tip fitting
anti-clockwise if viewed from
the rear of the leading edge.
The tip fitting should be
rotated a maximum of 5 mm.
ADJUSTING MAINSAIL BATTEN TENSION
Batten tension can be set using the following guide:
•
Check batten is inserted fully into its pocket by pressing firmly on the end of the batten
beak with the heel of your hand. The batten beak should protrude 5-7mm past the trailing
edge when clip is closed.
•
Hook the beak in the sail and start to clip the batten, the beak should be at approximately
30 degrees to the batten shaft as tension starts to come on the clip, and should not be
difficult to close.
•
With your eyes level with the trailing edge, look along the length of the batten toward the
leading edge. As you close the clip and the sail tightens, the batten should start to make a
small ridge on the sail near the leading edge - no more then a couple of millimetres.
•
Make adjustments of one full-turn at a time in between checking.
ADJUSTING BATTEN STRUT TENSION
•
As you start to close the folding clip, tension should start to come onto the clip at
approximately 30 degrees.
•
As the clip is closed, the sail should become tighter without obvious wrinkles. The clip
should not be difficult to close.
•
Make adjustments of one full-turn at a time in between checking.
