Composite-ARF SuperXtra 330L (3.1m span)
The last job is to connect the back servo to the rudder
horns with the cables supplied. Cut the 2 slots for the
cables to exit the fuselage about 3mm high and 40mm long.
the back edge of the slots starts at the front edge of the
balsa bulkhead in side the fuselage, and the centre of the
slot should be 22mm (7/8") above the bottom chine (corner)
of the fuselage. Mark the slots on a piece of masking tape
stuck to the fuselage, and cut out with a very sharp knife,
and adjust with a small file.
Make the pull-pull wires for the rudder from the hardware
supplied, with a loop at the front that goes over the hooks
on the output arms, and a quick-link with turnbuckle/thread-
ed end and locknut at the rudder end. For security pass the
closed loop cable through the supplied 'crimping tubes' 2
times before squashing flat with pliers (see photo on page
20). Make sure that the wires are tight, and check and
adjust after the first few flights as the cables straighten out.
Even a small amount of slop will prevent your Extra from
perfect tracking.
