Special Note:
It is suggested to charge your radio system before starting to build.
Following the manufacturer‘s instructions, connect your transmitter
and receiver batteries to the system‘s charger. This way the radio will
be ready when it is time to install and test the radio components.

MARK THE CENTERLINE ON THE JOINER

❍

1. Draw a centerline on both sides of the plywood wing joiner

as shown.

PREPARE THE AILERON SERVO TRAY MOUNTING BLOCKS

❍

2. Locate the two 3/8" square x 1-11/16" (9.5mm square x 43mm)

aileron servo tray mounting blocks. Mark a centerline on the blocks.
Using the wing joiner as a guide, mark the wing dihedral angle on
both of the aileron mounting blocks. Set the blocks aside for use in
later steps.

EVEN THE WING ROOTS

❍

3. Using a flat sanding block or similar tool and 120-grit sandpaper,

sand the wing roots so they will fit together without any gaps. Do not
sand too much or the dihedral angle could change.

PREPARING THE WING SERVO CAVITY

❍

4. Using a sharp hobby knife, remove the covering from the wing

panels for the aileron servo.

TEST FIT THE WING JOINER

❍

5. Test fit the wing joiner in both wing panels by sliding the joiner

into the joiner cavity in the wing. The joiner should slide in with little
resistance up to the centerline that was drawn on the joiner. If the
joiner will not fit in the cavity, lightly sand any uneven surfaces from
the joiner edges, sides or ends. Caution: A snug fit of the joiner in the
joiner cavity is desired. Use caution not to sand the joiner excessively.

VIEWING THE WING DIHEDRAL

❍

6. Pay close attention to the orientation of the wing joiner in

relation to the wing panel, creating the dihedral angle as shown. Test
fit the wing panels together. They should fit flush against each other
without any gaps.

Note: When performing the following steps, be sure to use a
sufficient amount of epoxy to form a complete and solid bond
between the plywood wing joiner and the two wing halves. This is
the most important glue joint in the entire airplane.

Please read through the following three steps before mixing any
epoxy. You must complete these steps within 20 minutes from the
time you mix the epoxy.
