You will run the two lines that are going to connect to the outside control horns
4.
through the two small outside holes in the F3 bulkhead, one on either side.
You will run the two lines that are going to connect to the inside control horns through

the large rectangular cutout underneath the rear battery mount support of the F3
bulkhead.
Route the cotter pins through the holes in the micro connectors for the appropriate
6.
control horn, push them through about 1/4", and then tighten the screws down.
Run the other end of the thread through the inner hole of the rear control horn. With

the control surface straight back, tighten the thread and tie it off. Set the knot with a

Step 11: Installing the Aileron Servos

Next, you are going to install the aileron servos. These steps are for one aileron, so you
just need to repeat the process for the other aileron.
For each aileron servo, you will need:
•
Clear packing tape
•
1 - 1/32" x 18" thin music wire for the tailskid and pushrods
•
1 Micro pushrod adjuster
All of the pictures shown in this section are of the bottom of
the left wing.

Installing the servos
Insert the servo through the aileron servo mount, dropping it in from the top of the
1.
opening so that it's actually facing upside down when the wing is flipped right side up.
Line up the aileron with the outside edge of the wing, making sure that the control
2.
horn is facing the wing, that the beveled edge is pointing towards the ceiling, and that
the whole mess is butted up against the wing.
Tape each aileron to the wing using clear packing tape, along the side without the
3.
bevel.
Using the thin music wire, z-bend one end and insert it into the correct hole of the
4.
control horn.
Correct Control Horn Hole Selection
Hole closer to the control surface = more throw
Hole further from the control surface = less throw
