Wing Assembly Continued:
Hinges:
We recommend installation of the hinges with Wood
glue. Oil the moving parts of the hinge liberally. Then
insert wood glue into the holes where the hinges will
be mounted. After aligning and installing the hinges,
wipe off any excess glue and apply a little more oil to
ensure the glue will not setup in the hinge. Use low-
tack masking tape to hold the control surface in place
while the glue dries.
Servo and Linkage Installation:
Install the servos into the servo trays. Install the ser-
vos into the “deeper side” as this will give proper
alignment. Use long servo arms and extend the arm
through the opening in the servo cover plate. Align
the servo and mount so that the servo mount ends do
not extend past the sides of the plate and adjust the
servo position so that the arm is centered in the open-
ing of the plate. Glue the tray to the plate.
The opening in the wing will have to be adjusted to fit
the tray. If you do this tightly, it helps hold the entire
assembly in position.
Soak the frame in the opening of the wing with thin
CA. This will stiffen the part and ensure the servo
mounting screws are held firmly in place.
NOTE: The ailerons openings are position “opposite”
each other whereas the flap servos are installed “to
the same side”. This way, the aileron servos naturally
move in opposite directions and the flap servos natu-
rally move in the same direction.
We routed the flap servo extension out the rear open-
ing in the wing and the aileron servo extension out
the front opening. When installing the wings, this
prevents confusion.
Position the control horns back from the servo arm so
that the linkage does not bind. Flaps use the Z-Bend
rod, Ailerons use the all-thread. Use wood screws to
mount the horns into the hard-plates in the control
surfaces. Mount the by drilling pilot holes and en-
sure they will not pull-out by using wood glue on the
screws.
Wing Tip Tanks:
There is a left and a right. Remove the covering from
the mating surfaces before gluing. Also, look at the
tanks from the front before the glue dries to ensure
they are aligned properly. We used slow-cure epoxy
and masking tape to hold them in place so that we had
time to adjust the alignment if necessary.
Main Gear Installation
Install the strut and wheel on the landing gear first.
1. The strut at the wheel end is slightly offset. The
longer side goes toward the wheel.
2. The wheel is retained with an e-clip and the axle is
held onto the strut with a set screw. Install the e-clip
first, then put the wheel (don’t forget the bushings)
onto the axle (screw heads facing out). Slide the axle
into the strut. Adjust the position to be as tight as pos-
sible while still allowing the wheel to move freely.
Use blue thread-lock to hold the set-screw in place.
3. The Strut is attached to the landing gear with two
set screws. Align the strut so that the wheel is perpen-
dicular to the retract. Make two flat spots on the strut
attachment stud that match the set-screw positions.
Use blue thread-lock on the set-screws to hold them
in place.
Now that the strut is in place, position the gear so that
the wheel fits nicely into the wheel cup. Try to make
the gear be positioned outward as far as possible.
Install air-tubes on the gear and bolt it in place with
the heavy duty wood cap screws provided. It is IM-
