14. The next step is to deploy the sprogs and secure them in position. Before doing so, working
through the sprog access zippers, preflight the following items:
a. The remaining internal ribs to confirm that they are fully zipped up.
b. The sprog hardware, including the leading edge sprog brackets, the attachment of the sprogs
to these brackets, and the sprog cable attachments at both ends of each sprog cable.
c. The leading edge crossbar junction hardware, including the nut, bolt and safety ring at this
junction and at the bottom side wire attachment to the crossbar.
To deploy and secure each sprog, swing the sprog away from the leading edge and align it in the
center of the rear end of the sprog access zipper, such that the rear end sprog paddle lies below
both the transverse batten and the short piece of bungee attached to the sail. Rotate the sprog as
necessary to align it such that the cable pulls directly from the top of the sprog. (Note: The sprog
should align easily and remain in this position - with the tang on top. If it will not remain aligned
properly, there is probably a twist in the sprog cable. To fix this, dismount the sprog from the
leading edge and rotate the sprog around the cable until the twist is removed.) Pull the loop of
bungee cord over the end of the sprog to secure the alignment. (The bungee does not need to be
tight around the sprog, however, if the bungee is so long as to be very loose on the sprog, pull it
over the sprog end twice, forming two loops.) Fully close the sprog access zipper. Note: Do not
lift on the sail at or near the trailing edge while trying to close the sprog access zipper. If you want
to lift the wing to gain easier access to the underside of the glider, lift the wing by the leading edge
tube.
15. Attach the bottom front wires to the bottom of the nose. Install the keyhole tang over the keyhole
collar by pulling down on the nose of the glider while pressing the tang upwards over the collar.
Remember, it is the pulling down of the glider's nose rather than the upward pressure on the tang
that allows you to install the tang over the collar. Make sure that the tang is fully seated in the
collar, and that the button lock pops up in front of the tang, locking it in place.
