Glider Tuning
CG adjustment
This has already been covered in the section of this manual on using your wing tufts. Wills Wing
recommends that tuning other than CG adjustment be performed by your Wills Wing dealer.
Turn trim
Turns are caused by an asymmetry in the glider. If you have a turn, first try to make the glider sym-
metrical in every way. If a turn only appears at VG settings of 3/4 to full tight, it may be an indication
that the sprogs are set asymmetrically. See the section below on tip wand receptacles.
Airframe
Check the leading edges for possible bent tubes. Check that the keel is not bent to one side.
Check for symmetrical twist in the leading edges by checking for symmetry in the alignment of tip
wand receptacles.
Battens
Check the battens for symmetrical shape.
Tip Wand Receptacles - rotational alignment
The plastic plug which fits directly into the rear leading edge determines the rotational alignment of the
tip wand. This plug is secured against rotation by a small screw in the end of the leading edge. There
are five holes in the plastic cap, allowing for two notches of rotational adjustment on either side of the
normal, center hole. Prior to removing the securing screw to rotate the plug, note the position of the
scribe mark on the cap relative to the label on the rear leading edge. If the plugs are not each set at
the neutral position in the center of the label, take note of where they are so you will know what your
starting point is.
Sail tension
Check for symmetrical sail tension on the leading edges. In order to check this, sight the hem of the
sail at the bottom of the leading edge tube relative to the noseplate on each side. Leading edge sail
tension is adjusted by changing the mounting hole where the tip wand cam lever mounts to the sail (1/
