Wing
The wing consists of two panels which are joined using a steel rod before being screwed to the
fuselage. No additional retention measures (e.g. adhesive tape) are required.
The first step is to install the aileron servos. The maximum thickness is 13 mm, and the servos
should be metal-geared types.
The location of the servo wells is already marked in the veneer, but they are concealed by the
covering film. Use your fingertips to locate the circular outlines on the underside of the wing
panels, and run the tip of a sharp knife blade round the circumference. The veneer over the servo
well can now be removed, complete with covering film.
The Styrofoam can now be removed to the point where the top wing skin is exposed. Take care to
avoid damaging the end of the plastic sleeve through which the servo lead will pass later.
But off the servo plug complete with a short length of cable, and extend the lead attached to the
servo to a total length of 25 centimetres - measured including the piece you have cut off (including
connector). Do not re-attach this piece yet!
Draw the servo lead through the plastic sleeve in the wing, starting from the servo well, and allow
it to trail out of the wing root rib. The short length of cable with the connector can now be soldered
to the cut end.
Set the servo to neutral (centre) from the
transmitter. This is a good time to check that
the servo rotates in the correct direction!
Now fit the output arm on the servo shaft: the
lever should be angled towards the wing
leading edge by about 15 degrees at the
neutral position. Fit the output arm retaining
screw.
The servo can now be glued in the well using
hot-melt adhesive. Check that the output arm
is not obstructed in its arc of movement. Take
great care not to get glue on the output arm!
The aileron linkage is assembled from a pre-
formed steel rod, a threaded coupler and a
pinned clevis. Measure the correct length of
the wire pushrod, cut it to length, and solder
or epoxy it in the threaded coupler.
Glue the horn in the aileron using five-minute
epoxy. Note that the clevis linkage hole
should line up exactly with the aileron hinge
pivox axis.
The final step is to trim the servo well cover to
fit neatly, and fix it to the wing using adhesive
tape.
Check from the transmitter that the linkage
operates smoothly and freely, and does not foul the servo well cover. Repeat the whole procedure
with the second wing panel.
Fuselage
The canopy is detachable, to ensure that the battery can be swapped easily during a flying ses-
sion. It is held in position by a length of steel wire glued to the inside of the moulding.
The canopy is opened by carefully sliding it forward over the fuselage flange until the rear end of
the wire retainer is released. The canopy can now be lifted up at the rear and removed.
To replace the canopy, slip the front end of the retainer under the front fuselage flange, then slide
the canopy over the fuselage until the rear end can be pushed down under the fuselage flange.
Now slide the canopy back again until you feel the moulding engage in the fuselage recess.
