BUILDING INSTRUCTIONS
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. 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.
Assemble the Wings
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 servo hatch covers. Make
adjustments with a hobby knife to the blocks as necessary
for your brand of servos. The block positions are designed to
fi t a standard size Futaba brand servo.
❏
1. Cut three arms from a four-armed servo arm for each
aileron servo. Enlarge the outer hole of the remaining arm
with a 5/64" [2mm] drill bit. 3D aileron throws will require 1"
[25mm] or longer servo arms.
❏
2. Attach a 6" [152mm] servo extension to each aileron
servo and secure the connector using 1-1/2" [38mm] pieces
from the included heat shrink tubing. Center the servos with
your radio system and install the servo arms to the servos
perpendicular to the servo cases as shown. Be sure to
reinstall the servo arm screws into the servos.
❏
3. Position each servo against the undersides of the aileron
servo hatch covers between the mounting blocks. Shim the
aileron servos away from the hatch covers approximately
3/64" [1.2mm] to isolate them 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
servos) 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 servos onto the hatch covers using the hardware
supplied with the servos. If the servos you are using don’t fi t
between the blocks, remove material for the wood blocks.
