7. If you are using the servo we used, Futaba S3102,
the instructions for the release pin that follows will
be correct for this servo. You may need to adjust the
overall length of the pin for your servo choice. From a
2-56

6" threaded wire, bend and cut the release pin
as shown in the sketch.

8. This photo shows the former in the orientation it
will be when it will be glued into the mount. Use the
former as your guide and cut the holes into the ABS
plastic mount as shown. Refer to the photos in the next
step for a reference of what to cut.
❏
9. Glue the former into the bottom of the plastic mount.
For better adhesion, roughen the plastic with some 220
grit sandpaper before gluing the parts together.

10. Install the servo with the screws that came with
the servo. Center the servo and install the servo arm.
❏
11. Using a 5/64" [ 2 mm] drill open up the outer
hole in the servo arm. Install the release pin into the
servo horn.
❏
12. Install the servo box into the plywood former
without any glue. Drill two 1/16" [1.6 mm] holes
through the ABS plastic mount into the plywood servo
box. Do this on both sides of the mount. After installing
the screws, remove the screws and the mount. Apply
a couple of drops of thin CA glue in the holes. After
the glue has hardened, reinstall the servo box and
the screws.
