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 4.
❏
2. Remove the tape and separate the elevators from the
stab. Use a covering iron with a covering sock on medium
heat to tighten the covering on the wings, fuselage, etc. if
necessary. Apply pressure over sheeted areas to thoroughly
bond the covering to the wood. Caution: The Factor 3D EP
ARF was designed to be strong where needed, but light weight
for excellent fl ight performance. Care must be taken when
assembling the plane to avoid damage.
ASSEMBLE THE WINGS
Install the Ailerons
Do the right wing fi rst so your work matches the photos
the fi rst time through.
Install the Aileron Servos and Pushrods

1. Inside the servo bay a string is taped. Carefully
remove the tape and string from the servo bay. Tie the string
to the servo lead. Pull the string and the servo lead through
the wing. Untie the string from the lead.
❏ ❏
2. Install the servo into the servo opening. Drill a 1/16"
[1.6 mm] hole though the servo mount, into the wood in the
wing. Install and then remove a servo mounting screw into
each of the holes you have drilled. Apply a drop of thin CA
into the holes to harden the threads. Once the glue has cured
install the servo into the servo opening. Center the servo and
then install a servo arm as shown. The arm should be pointing
towards the wing root.

3. Drill a 5/64" [ 2 mm ] hole through the hole in the servo
arm as shown.

5. Cut the
mounting plate from
the control hor n.
Attach the clevis in the
outer hole of a nylon
control horn. Place
the control horn in line
with hole you drilled in
the servo arm. When
positioned properly
the control horn will
rest on a hardwood
plate in the aileron.
Mark the location of
the mounting holes
onto the aileron. Drill
a 1/16" [1.6 mm ] hole
on the marks, drilling
through the plywood
plate but not through
the top of the aileron.
