PREPARATIONS
❏
1. If you have not done so already, remove the major parts
of the kit from the box and inspect for damage. If any parts
are damaged or missing, contact Product Support at the
address or telephone number listed in the “Kit Inspection”
section on page 7.
❏
2. Carefully remove the tape and separate all the
components. Use a covering iron with a covering sock on
medium/high heat to tighten the covering if necessary.
Apply pressure over sheeted areas to thoroughly bond the
covering to the wood.
BUILD THE WING PANELS
Install the Aileron & Flap Servos & Pushrods
Before completing this section, confi rm that the servos
that you will be using will properly fi t between the servo
mounting block locations on the aileron and fl ap servo
hatch covers. Make adjustments as necessary for your
brand of servos. The block locations shown in this section
will fi t a standard size Futaba brand servo.
❏ ❏
1. Trim the covering from the servo arm cutouts in the
aileron and fl ap (if you will have operational fl aps) servo hatch
covers. Use epoxy to glue the 3/4" x 3/4" x 5/16" [19 x 19 x 8mm]
hardwood servo mounting blocks to the inside of the aileron
and fl ap hatch covers. Be sure that the blocks are aligned
over the rectangles with the grain direction perpendicular to
the covers. Allow the epoxy to cure undisturbed.
❏ ❏
2. Cut three arms from a four-armed servo arm for the
aileron servo. Enlarge the outer hole of the remaining arm
with a 5/64" [2mm] drill bit.
❏ ❏
3. Attach a 9" [229mm] servo extension to the aileron
servo and secure the connector using tape or heat shrink
tubing (not included). Center the servo with your radio
system and install the servo arm to the servo perpendicular
to the servo case as shown. Be sure to reinstall the servo
arm screw into the servo.
❏ ❏
4. Position the servo against the underside of the aileron
servo hatch cover between the mounting blocks. Shim the
aileron servo away from the hatch cover approximately 3/64"
[1.2mm] to isolate it from vibration (a business card folded in
thirds works well for this). Drill 1/16" [1.6mm] holes through
the mounting tabs on the servo case into the blocks. Thread a
servo mounting screw (included with the servo) into each hole
and back it out. Apply a drop of thin CA to each hole to harden
the wood. When the CA has dried, install the servo onto the
hatch cover using the hardware supplied with the servo.
