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 the previous page.
❏
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 Eagle 580
was designed to be strong where needed, but lightweight
for excellent fl ight performance. Care must be taken when
assembling the plane to avoid damage.
ASSEMBLE THE WINGS
Do the right wing fi rst so your work matches
the photos the fi rst time through.
❏ ❏
1. Inside the servo bay a string is taped. Carefully remove
the string from the servo bay and tape it to the outside of the
wing to prevent it from dropping back into the wing.
❏ ❏
2. Install a 12" [305mm] servo extension onto the
servo lead. Secure the extension to the lead with tape, a
piece of shrink tube or some other method to keep them
from coming unplugged.
❏ ❏
3. Tie the string to the servo extension. Pull the string and
the servo lead through the wing. Untie the string from the lead.
❏ ❏
4. Install the servo into the servo opening. 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. Place a black retaining plate
onto each of the servo mounting fl anges. Then, screw the
servo to the wing using the hardware included with your
servo. Center the servo. Then, install a servo arm as shown.
The arm should be pointing towards the wingtip.

5. Thread a nylon clevis, 20 turns, onto a 6" [152mm]
wire pushrod.

❏ ❏
6. Attach the clevis in the outer hole of a nylon control
horn. Place the control horn in line with the hole that is 3/4"
[19mm] from the center of 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" [1.6mm] hole on the marks, drilling through
the plywood plate but not through the top of the aileron.
