Wires and Attachments
At the first sign of fray s or kinks the w ire should be replaced. Stainless steel cable work-hardens from
bending, especially where it enters or ex its a nico sleeve. The shrink tube covering the nico sleev e should
be peeled back periodically to inspect the cable. Constant ex posure and set-up on rough and rocky
ground w ill shorten the riggings life. Wires are not ex pensive and are simple to replace. They are also a
v ital structural member of the hang glider. If the glider is periodically ex posed to salty air, some rust may
form on the cable. This is nothing to be concerned about and is caused only by some impurities mixing up
in the cable during cable manufacture. The cables are stainless steel and w ill not corrode due to ocean air
ex posure.
Tubing and Bars
Once again contact or immersion in salt air or water is a major concern and w ill require removal of end caps and
a thorough flushing and dry ing. Corrosion and electrolysis set in amazingly quickly and will dramatically reduce
the strength and life of the parts involved. Follow the maintenance schedule conscientiously. Examine the bars
for dents, bends, w ear spots and corrosion ev ery pre-flight check. If any damage is noticed, replace the bar, but
also determine how that damage was caused and take steps to avoid repeat damage occurring.
Hardware and Bolts
The bolts can be bent in a crash or hard landing. These should be replaced. All bolts should show exposed
thread above the locknuts.
Special Note to Coastal Fliers
The Litespeed uses thin w all 7075 tubing throughout the airframe, w hich is considerably more v ulnerable
to corrosion than the 6061 alloy used on prev ious gliders. The 7075 suffers corrosion for tw o reasons.
7075 has a thinner wall thickness (0.9mm compared to 1mm) w hich means that a small amount of
corrosion has a larger effect. 7075 alloy also contains a large portion of copper, and this is the most
significant reason for corrosion.
If the tubing is ev er directly ex posed to salt w ater it must be thoroughly rinsed with fresh w ater as soon as
is possible. If y our glider is ex posed to coastal air y ou must rinse the inside and outside of the tubes w ith
fresh w ater once every 6 months. If y our glider is stored near the coast y ou need to keep y our glider in a
dry location such as a closed garage.
It is possible to put a film of linseed oil on the inside of the leading edge tubes. This will considerably help in the
prev ention of corrosion. To do this the leading edge tubes must be removed from the glider. Fully disassemble
the leading edge removing all sleeving. Pour a small amount of linseed oil into each tube and sleeve rotating the
tubes as you pour to entirely coat the inner wall. After this is done, apply a second coat by wetting a cloth with
linseed oil, attaching it to a broomstick, and pushing it through the length of the tube. Note that the front section
leading edge has a series of inner nylon rings, thus the cloth must be pushed though each end individually.
Nev er try to straighten a bent bolt. Straightening the bolt w ill cause significant w ork hardening
and w ill dramatically reduce strength. All Moy es hang gliders use specially sourced aircraft
quality bolts throughout the airframe, and should only be replaced by the ex act bolt ty pe available
from your local Moy es Dealer.
