6.
Connect an 18” servo extension to the spoiler lead and secure it
with a clip or heat shrink tubing. Thread the extension through the
inner end of the wing panel as before.
11.
Install the flap servo mount using epoxy. Align the mount with the
marks made in the previous step. Remove any epoxy that squeezes
into the mounting lug slots or the inner base of the mount which
may interfere with the servo. Ensure the mount bonds to the wing
spar as well as the surface and that the servo arm will align with
the flap control horn. Allow epoxy to fully cure.
8.
Carefully trim the webs from the servo mounting lugs. Test fit the
servo in the servo mount. The servo should be a very snug fit in the
mount.
13.
Center the servo and install the control horn angled slightly toward
the trailing edge of the wing.
14.
Slide the servo into the mount as shown.
7.
Using hot glue or contact adhesive, such as Deluxe Systems
Foam 2 Foam (DLMAD34), secure the aileron and spoiler leads to
the spar at the front of the servo hatch. Doing so will keep the leads
from shifting and interfering with the flap servo arm and pushrod.
12.
Cut the flap servo arm to length.
9.
Carefully scuff the wing flap servo mounting surface for the servo
mount using either a rotary tool on low speed or 80 grit sandpaper.
Only lightly scuff the inner surface of the wing panel to give the
epoxy something to grip.
DO NOT
sand through the surface of the
wing panel. Clean the mounting surface thoroughly with denatured
alcohol or IPA.
15.
Using the acetate template provided, create a servo retention plate
using 1/8” and 1/16” ply.
10.
Measure and mark the flap servo hatch opening, 12mm from the
rear recess line and 17mm from the outer recess line, as shown in
the illustration.
