WING ASSEMBLY/ENGINE POD ASSEMBLY

The ailerons are in place with hinges already in their slots.
Remove any tape that may be holding things in place. Hinge the
ailerons by securing the "CA" hinges in place. Begin by making sure
the CA hinges are in proper position and the ailerons have minimal
gap between them and the trailing edge of the wing. (Have a paper
towel ready in case you have to mop up excess glue.) Hold the wing
up on the leading edge and, working from the bottom of the wing,
carefully put a few drops of THIN CA where each hinge goes into the
wing. It should wick down into the wing. Do the same, working from
the top of the wing. Turn the wing over so it is resting on the trailing
edge and repeat where the hinges go into the ailerons. When done,
you should have applied thin CA to all surfaces of each hinge. After
the glue has "fired", make sure the ailerons are free to move by flexing
back and forth. Also make sure the glue joint is secure by tugging on
the ailerons.

Cut the covering material away from the aileron servo cutout hole.
Put the plywood aileron servo tray in position and mark the outer edges
of the plate on the covering material. Being careful to not cut into the
balsa, remove the covering material where the aileron servo tray will
glue to the wing. Glue the aileron servo tray into position.

Mount the aileron servo in place. Screw the nylon horns onto
the torque rods until the top of the horn is flush with the top of the
threaded portion of the torque rod. Link the servo to the aileron
torque rods using the threaded rods furnished. Use a clevis on the
torque rod (threaded) end and a "Z" bend on the servo arm end (non-
threaded). Adjust for neutral with the servo centered.

The tip floats are attached to the wing with the furnished sticky
backed Velcro. Use a square on both the front and back of each tip
float. Position the tip floats on the outer bay of each wing with the
front of the float about 1/2" back from the leading edge of the wing.
Set the wing aside for now.
Engine Pod Assembly

The firewall and firewall braces should be glued to the engine
pylon. Also, holes for the engine mount, reinforcing screws, fuel lines,
and throttle should be pre-drilled. If any of these holes are not drilled
in your firewall, you will have to drill them accordingly.
Screw the two 4 X 35mm self tapping screws through the firewall
into the pylon to reinforce the joint. It is suggested that you use epoxy
to coat the entire firewall, front and back. This will fuelproof it plus
reinforce the glue joints. If you get epoxy in the holes, wipe it out
while the glue is wet, or drill it out when the glue is set.

Secure the engine mount assembly on the firewall using the four
screws and blind nuts furnished. (Normally, the engine is side-mount-
ed with the cylinder head on the right.)
