RIGGING THE JAVA COMP
The glider can either be rigged flat on the ground, or with the glider supported on its control frame. The
latter should only be attempted in light wind conditions but is useful in confined spaces or where the
terrain is likely to cause soiling or damage to the sail.
Flat rigging
Lay the glider on the ground with the nose pointing into wind. Unzip the bag and roll the glider so it is the
right way up. Take the bag off. (If you tread on the inside of the bag any dirt that you get on it will be
transferred to the glider when you put the bag on later.)
Take the glider ties off and take the battens out from on top of the sail.
Making sure that you do not lift the tip high above the ground (to ensure that you do not bend the nose
plates), move one wing out a little then the other. Then move the other out a little. It is important to move
both wings out slightly (the tip less than 1m) before moving through larger arcs. (The reason for this is
that the geometry of the cross tubes does not allow one wing to be pulled out far without the other moving.
If you do this when the wings are nearly parallel leverage you exert is very high. It is possible to put very
high loads where you might not at first imagine, bending the nose plates and worse.) Continue until both
wings are about three quarters of their maximum travel. If there is any resistance check to see what is
causing it and free the problem before continuing. Do not attempt to force the wings apart. Lift the wing
preferably by the wing tip but if you must use the sail hold it by the batten pocket ends on the trailing
edge.
As you open out the wings, carefully open the area with the inner washout rods. Lift the rods from
alongside the leading edge over the cross tubes. Make sure that their ends are aligned under the span-wise
batten.
Put the bottom bar on and insert the two stainless pins from the back of the base bar and fit the safety
rings. PUT THE RINGS IN IMMEDIATELY. DO NOT LEAVE IT UNTIL LATER. Thread the VB. cord
through the cleat on the base bar. Tie a knot in the end of the cord.
Lay the battens on the ground and pair them up, red with green, and check that corresponding batten pairs
have the same profile. This is a good habit to get into as it will reduce the chances of taking off on a glider
with a turn caused by asymmetric shaped battens. (Periodically the battens should be checked against the
batten profile.)
Insert the battens smoothly starting with the first ‘normal’ batten in from the wing tip and working from
the tip towards the centre chord. Insert the batten in the second from the tip batten pocket. (The
compression strut is inserted later in the rigging sequence.) (On a new glider a little silicon spray on the
batten ends will help them slide in smoothly. Once again make sure the washout rods pass under the span-
wise battens.
Keeping the trailing edge low and slowly easing the battens into their respective pockets will help increase
sail life.
The glider can now be tensioned. Remove the split ring from the special bolt located through the rear of
the keel tube. Using the attached elastic cords, pull the cross tube restraint webbing back. Check that the
elastics are not twisted. Locate the stainless tang over the stub of the bolt and replace the split ring. If the
tension feels too tight stop and see what is causing the problem. DO NOT JUST FORCE IT. (Consult the
trouble shooting area of this manual for possible causes.)
