Ribs
The ribs form the wing shape and hence dictate the whole performance of the wing. They need treating with care,
and since they are subject to constant tension both during flight and rigging, they tend to lose their shape and
flatten out. It is essential that they are reformed at frequent intervals and checked against the template. If you
have to rig regularly, you should check your rib profiles every 25 hours. If you leave your Quik-GTR rigged,
check the ribs every 100 hours. The best way to reform the rib is to hold it against your knee and, whilst applying
pressure to bow the rib, slide it side to side over the area you want to bend. Direct point bending will usually
result in either a poor shape or a broken rib. If you kink a rib, do not fly with it; you should replace it before the
next flight.
The outer 5 batten spring adjusters should be wound out, inspected and lubricated sparingly with grease,
annually.
Flattening of the camber in the nose and root battens will cause the stall speed to rise.
Washout Rods
The wing is provided with washout rods which define a twisted (washed out) profile which maintains pitch stability
at low angles of attack. The inner one is mounted at the leading edge by a cable and rests over the cross boom,
protected by a plastic sleeve. The outer one is attached by a universal joint and cable system. Both rods are
linked together by a nylon cord which runs from the wing root. The cord pulls both rods into the correct position
automatically as the wing is opened out. A bungee retracts both rods to the stowed position for transport.
The inner washout rod is of fixed geometry and must conform to drawing YQE-0700. The outer washout rod is
adjustable by detaching the cables at the 5mm bolt and rotating it in the front threaded adjuster. 1 turn =
approximately 6mm of vertical travel at the rod tip.
Washout Rod Settings
The washout distribution must be as shown in the drawing YQF-051 below. The settings must be checked after
any incident where wing damage is suspected, before wing tuning and during any wing rebuild.
Washout rods should never be lowered from the optimised
positions defined on drawing YQF-051. Dangerous pitch
instability may result.
