1.2.3. Wing Wiring

Openings must be ground in the panel root ribs, using the approx. measurements provided,
for the wiring and pneumatic lines. The corresponding openings in the fuselage may be cut
smaller. The larger opening in the wing rib allows easier routing of the wires/tubes. A factory
formed opening is provided in the main spar, to allow the passage of the servo/lighting wires
and pneumatic tubes from the front part of the wing to the rear, in the vicinity of the flap servo
bay. This makes routing the wiring out to the wingtips easy.
The pneumatic tubes can also be routed thru this opening to the gear units.

A wood support rib/former is located under the fiberglass skin at the root with an opening
approximately the size of the given measurements. The marked area can be cut a bit
smaller, then sanded to match the cutout in the wood. This is preferred, as there is then no
damage to the wood part.
To prevent the wires and tubing from flopping around inside the wing panel and possibly
becoming disconnected, servo-plug security and retract tubing clips (commercial items) or
even tape is to be used. This applies also to all other connections.
