Pull-Pull Cable and Final Gear Door Installation
-The pull-pull cable is looped through the landing
gear horns and around the strut. This will allow easy
adjustment once the pull-pull cable is assembled.
-We routed the cable through scrap Pushrod Housing
Tubes. This will keep the cable from getting tangled
in the landing gear. The pushrods should be cut long
enough to clear the center bulkhead.
-The pull-pull cable has the standard threaded rods,
clevises and crimp pins. Loop and crimp to length.
-Once the servo and cable are adjusted and centered
and tightened, center the wheel/strut too and glue
the cable into place.
NOTE: The cable should be tight enough to provide
positive steering control but loose enough so that the
gear can go down into position easily. If the cable is
too tight, the gear will not lock into the down posi-
tion.
Once the door linkage and steering linkage is work-
ing properly, permanently position the horns and
hinges on the door by applying light glass cloth over
the hinges and horns where they are glued to the
doors. Then soak thin CA into the glass cloth.
NOTE: Do NOT allow glue into the hinge. Again,
we recommend oiling the hinges so that glue cannot
get into them and ruin them.
Tail and Servo Installation
Tip: Please follow the order of assembly
and trial fit and check alignment before
gluing.
-The vertical stabilizer is glued to the fuselage. It
is keyed by dowels and by the rear hinge-line spar.
TRIAL FIT the vertical stabilizer. Make sure it is
vertical and perpendicular to the wing. Install with
epoxy glue.
-The horizontal stabilizer must be centered and made
level with the wing. Remove the covering before
gluing into position.
IT IS IMPORTANT FOR YOU TO MAKE ADJUST-
MENTS TO ENSURE PROPER ALIGNMENT.
TIP: Push the stabilizer forward so that there is
a gap at the rear of the opening. This is the space
for the elevator joiner.
TIP: Use slow cure epoxy. First outline the glue
joint with masking tape so that excess epoxy can
be easily removed and will not damage the cover-
ing.
-The elevator and rudder servos are bolted into the
servo opening. We used 750mm extensions and rout-
ed the extensions through the small openings in the
bulkheads.
-The servos are covered with the included plate and
small wood screws.
-The elevator hinges and metal elevator joiner must
be installed at the same time. Glue the metal joiner
into the elevator halves after routing it through the
opening at the rear of the stabilizer with epoxy.
-The horns are positioned into hardwood blocks in
the control surfaces. The rudder horn is installed with
wood screws. We recommend gluing those screws
into the rudder with wood glue. The elevator horn is
held in position with a standard horn backing plate
and 2mm machine screws.
-The pushrods are threaded end type with metal clev-
ises. Some adjustment to the pushrods will be re-
quired for proper alignment.
