clear the servo wire as it exits the servo case.
The aileron servo extension should run along the wing
in front of the main wing spar before passing through
the spar around the centre section. The extension lead
must be restrained where it runs past the flap linkage.
The Aileron linkage is assembled from the 42mm
length of M3 all-thread fitted with a locking nut at
each end and an M3 steel clevis. Fit this on the outer
hole of a 20mm radius arm.
Finally fix the servo cover plate using four 2.9 x
10mm sheet metal screws.
The flap servos are mounted into the servo cut-out pre
cut in the wing rib accessible through the main gear
opening in the wings lower surface. The servo is
mounted with the servo arm nearest the wing trailing
edge.
We recommend a servo with minimum 9.0kg torque
as the Hawk flaps are quite large and the actuating
horn offset from the hinge point is relatively small.
C-ARF strongly recommends using the JR 8411/8711
servo for the flaps, fitted with a heavy duty servo arm.
Very little movement is needed for total flap travel, so
the arm can be cut leaving only the inner two holes.
The flap servos are fitted using four 2.9 x 13 sheet metal screws-note do not use the
stock servo mounting screws
Some time should be spent cleaning up the factory cut openings for the flap linkage with
a file to remove any material left around the opening. This will stop any binding of the
linkage during flap operation. At least 60mm of flap movement is required in landing
mode.
The flap linkage is assembled using two M3 x 200mm all-thread rods fitted with a
locking nut at each end and a steel M3 clevis. This benefits from some additional
