o o 3. Attach a 24" [610mm] servo extension to
each aileron servo and secure the connector using
tape or heat shrink tubing. Center the servos 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.
o o 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.
o o 5. Use the strings taped inside the aileron servo
hatches to pull the servo leads through the wing ribs.
o o 6. Thread a #2 x 3/8" [9.5mm] self-tapping
screw into each hatch mounting hole in the wing and
back it out. Apply a drop of thin CA to each hole to
harden the wood. Install the aileron hatch cover to
the wing as shown using four #2 x 3/8" [9.5mm] self-
tapping screws.
o o 7. Thread a nylon clevis 15 complete turns onto
a 6" [152mm] pushrod. Slide a silicone clevis retainer
onto the clevis and connect the clevis to the outer
hole of a nylon control horn.
o o 8. Position the control horn onto the aileron
between the two corrugations that are inline with
the aileron servo arm. Align the holes in the control
