Preflight-check
A preflight-check is essential before hooking the wing on the trike. To that effect lift the nose of the wing shoulder
high.
•
Check the camber of the two leading edges.
•
Check the thimbles of the front lower longitudinal cables and the correct fastening of the tensioning device and
the push-pin.
•
Set the wing on its nose. Slide your hand along the leading edges to check for possible defects.
•
Check the cross-bar/leading edges link by unzipping the bottom surface access. Check the fastening of the
lateral cables is correct and the sail is not snagged.
•
Check the fastening of the sails at the wing tips, as well as the correct positioning of the two pivots (the two
screws should be positioned directly in line with the tip strut) and the tip struts.
•
Check whether the battens and their fastening rubber bands are securely positioned, check the condition of the
back-up cable and their fastening to the sails.
•
Check whether any of the upper cables is circled around the king post (watch the off lines).
•
Check the fixing of the rear lower cables at the keel end.
•
Check the tension of the cross-tube tension cables, the position of the push-pin and its safety-lock, as well as
the condition of the loop that holds the sail centered.
•
Slip your hand along all the lower cables to detect signs of wear.
•
Check the hang point, the condition of the tension cables and ensure they are not crossed, check the buckle
which maintains them at the level of the king post and the strap restricting upwards travel of the cross-bars.

•
Roll banking limited to 60°
•
Inverted flight is forbidden
•
V.N.E. (never to be exceeded) : 110 km/h
•
Stalls authorized only in glide path with a progressive speed reduction and
throttle to idle position.
•
Over these limits, some stability loss or control, structural failure or
irreversible "tumbling" motions
Better handling will only be reached after about 10 flying hours and control during roll will be more difficult
during the first flights.
