•
Raise the nose of the wing and lift it on the 'A' frame.
•
Fix the front lower longitudinal cables in the locating rail under the nose plate with the tension lever
and the push-pin. Ensure that the pin is locked.
•
Lower the wing onto its nose. Slip bottom surface battens in their pockets and secure them with the
rubber bands.
•
Place the tip struts into the locating sockets on the leading edges by extending on the retaining
rubber bands. Slide your arm in the wing opening at the end of leading edge and lift up the sail to
simplify the operation.
•
Close the sail opening at the wing tip with the closing parts and their velcros.
•
When connecting the trike, slip the security fastening cable in the security strap at the king post
level, make a turn backward around the king post, slip it again through the security strap, then fix it
on the upper beam of the trike. The security cable should pass under the tensioning cables. This
operation secures connecting of the trike as well as fastening of the crossbar tensioning system, in
the event of violent shock-failure.
•
Fix the
nose bonnet with the velcros (essential point see "c" flying characteristics).
Dismantling
is carried out in reverse order of the assembling operations.
Before folding up the two half-
wings,
make sure that the tensioning device lever doesn't get stuck in the opening upper surface forward the
king post in order to avoid to hook one of the units of the sail or the structure when closing the leading
edges.
b)
Preflight-check
A preflight check is
essential before lifting the wing above the trike. To that effect, position the wing
horizontally after having connected the trike.
•
Check the camber of the two leading edges and correct attachment of the nose bonnet.
•
Check the thimbles and nicopress of the front lower longitudinal cables and the correct fastening of
the tensioning device and push-pin.
•
Slide your hand along the leading edges to check for possible defects.
•
Check the crossbar/leading edges connection by unzipping the lower surface access. Check fastening
of the lateral cables is correct, the condition of these cables and their nicopress and the sail is not
snagged on a metallic part.
•
Check the fastening of the sails at the wing tips as well as the correct positioning of the two sleeves
(the two screws should be positioned directly in line with the tip strut), the placement of the tip struts
and the closing of wing tips.
•
Check whether the battens and their fastening rubber bands are securely positioned, check the
condition of the reflex bridles and their fastening to the sails.
•
Check whether any of the upper cables is looped round the king post and if the reflex bridles are
correctly positioned in the pulley on the rear upper longitudinal cable.
•
Check the thimbles and nicopress of the rear lower cables at the keel tip.
•
Check tensioning of the crossbar cables, the correct positioning of push-pin and its safety, as well as
condition and fastening of the strap retaining the keel pocket.
•
Slide your hand along all the lower cables to detect signs of wear.
