into the ground when installing or removing the battens. When working with the
longest inboard batten it is helpful to lift the rear end of the keel slightly, and also to
insert the batten initially upside down, flipping it over after it is inserted about a
quarter of the way.
If you choose not to check your battens for symmetry before each flight, you should,
at a minimum check them once every five flights, or at any time that you experience
a hard landing or groundhandling mishap.
8. Spread the wings all the way and check all cables for any twisted thimbles or tangled cables. At
the rear of the keel, pull on the line that is attached to both the top rear wire and the sweep wire in
order to retrieve the sweep wire from inside the keel pocket. (Note: Sometimes the sweep wire
tang will catch on the front of the keel pocket at this point in the set-up. If this happens, reach
through the opening in the sail at the base of the kingpost, grasp the sweep wire, and work it
forward and aft while pulling gently on the line at the rear until you clear the interference.) Pull
the sweep wire out the rear end of the keel pocket. For maximum "leverage" insert the set up tool
in the loop of leech line attached to the sweep wire keyhole tang. Tension the sail by continuing to
pull back on the sweep wire and secure the sweep wire by installing the keyhole tang onto the
keyhole collar on the rear wire bolt. Make sure the tang slides fully forward in the slot on the collar
so that the narrow part of the keyhole slot is fully captive in the narrow part of the bolt collar, and
make sure that the button lock pops up behind the tang. Now install the top rear wire keyhole tang
onto the same keyhole collar, again making sure that the tang is fully installed, and that the button
lock pops up behind the tang. You can stow the excess line inside the neoprene sleeve on the rear
keel.
Never install the keyhole tang onto the keyhole bolt without making absolutely sure
that the tang is fully engaged on the narrow neck of the bolt, and tensioned forward
into the fully locked position. An in-flight disengagement of this attachment will
cause a complete loss of structural support of the glider and a total loss of control.
Never attach the pull string to the collar, even temporarily. Also, avoid applying any
forward, rearward, or sideways pressure on the button spring, or allowing the tang
to catch on the back of the button, as this can result in the button becoming bent
and not deploying properly.
