❏
Test fit the Fin/Rudder assembly into place
on the fuselage. Mark and drill a 3/32" hole
into the leading edge of the rudder to accom-
modate the tiller arm portion of the tailwheel
assembly. Test fit again and (if necessary)
notch the leading edge of the rudder to accom-
modate the tailwheel wire.
❏
Epoxy the stabilizer and fin onto the fuselage,
making sure the stabilizer stays in alignment
with the fuselage and the fin stays perpendicular
to the stab. Also make sure the tailwheel
assembly tiller arm slips into the hole you just
drilled in the leading edge of the rudder.
SERVO INSTALLATION
❏
Study the radio installation drawing.
Note that three servos are installed in the right
wing: the outermost servo is one of the two
aileron servos, in the middle is the throttle servo
and the rudder servo is on the inside.
In the outboard position in the left wing is
the other aileron servo; the elevator servo is on
the inside. Receiver and battery are foam
wrapped in-between these two servos and the
switch and charge jack are mounted to the
hatch in such a way that they don’t interfere with
the internal components.
❏
Use self-tap screws and grommets to mount
the servos to the rails in the wing so the output
arm will be in line with the slots you have
already cut. The throttle linkage will be dealt
with soon. Simply install the throttle servo
halfway between the aileron and rudder servo.
LINKAGE INSTALLATION
Elevator/Rudder Linkage
Hookup to the rudder and elevator is done
with “nyrod” pushrods consisting of an inner and
outer nylon tube. A threaded stud and clevis on
each end connect to both the servo arm and the
control horns.
❏
Take a piece of 120 grit sandpaper and
roughen up about 2" of the outside of one end
of each of the two outer nyrods. Slip this end
into the slot in the LEFT wing that you cut earlier.
