VB. MAINTENANCE
Due to the design of the Java Comp VB., its operation should be smooth and much easier than other hang
gliders.
To keep it this way, make sure that the ropes not twisted and clean. Remove grit or dirt from the upright
casting and replace the ropes if they show signs of wear. It is also important to keep the tension strop of
the glider untwisted.
VB. Set-up
The VB. on your glider should be factory set. However the ropes do stretch a little and it may be necessary
to adjust the ropes to retain full VB. Travel.
NEVER ALTER YOUR GLIDER OR VB. IN SUCH A WAY AS TO INCREASE THE
MAXIMUM TENSION OR REDUCE THE MINIMUM TENSION.
TUNING INSTRUCTIONS
Trim speed
The trim speed is adjustable by moving the hang loop forwards or backwards along the keel. Forward
movement will speed trim the glider faster, whilst rearward movement will slow it down. Only move the
hang loops in small increments ½ inch maximum.
Turns
A turn in the Java Comp is unusual. If your glider previously flew straight then the most likely explanation
is that you have damaged your glider. If a turn is detected first check the battens. Check them against each
other (making sure that they are the same on both sides) and then against the profile. Next check that the
batten elastic tension is the same on both sides of the glider. If there is still a turn check that the leading
edges are straight and undamaged.
A slight turn may be tuned out using the tip adjusters: The black plastic caps have a small hole drilled as a
reference. This reference is lined up with the self-tapping screw for initial assembly. (This is the datum)
The self-tapping screw should be removed and the black plastic cap turned slightly. The wing that is lifting
should have the washout increased (i.e. trailing edge lifted) while the wing dropping should have the
washout reduced (i.e. trailing edge lowered). Mark the leading edge with a pen or pencil before removing
the self-tapping screw and
ONLY ALTER THE WASHOUT AT THE TIP IN SMALL
INCREMENTS
. (MAXIMUM 3mm at a time.) The total movement should
NOT
exceed 10mm each side
of the datum (the hole for the self tapping screw.
DON'T FORGET TO REPLACE THE SELF-
TAPPING SCREW.
Washout at the tips
The washout at the tips can also be altered symmetrically, that is increase or reduce the washout on both
wings. Only small changes are needed and large changes are counterproductive. A small reduction in the
washout (2-3mm) will make the glider feel slightly lighter in pitch and show perhaps a slight increase in
glide performance. In smooth air the glider handling will probably appear much the same but if a wing is
lifted it will be more difficult to get down.
