14. Insert the pushrod through the outer pushrod tube
and through the screw-lock pushrod connector on the throttle
servo arm. Connect the clevis to the throttle arm on the
carburetor. Make any necessary bends in the pushrod so the
pushrod can actuate the throttle without contacting the motor
mounting box. When satisfi ed, adjust the pushrod position in
the screw-lock pushrod connector so that the throttle servo
properly opens and closes the carburetor. Use the radio
system to test the operation of the throttle. Tighten the SHCS
in the screw-lock pushrod connector and cut off the excess
pushrod 1/4" [6mm] behind it. Glue the outer pushrod tube
support to the second former and glue the outer pushrod
tube to the outer pushrod tube support.

15. CA glue the plywood fi ll line clip to the bottom center
of the fi rewall. The clip can be fuelproofed with epoxy. Cut
the fuel tubing coming from the tank to the proper length and
connect the carb line to the engine. The fi ll line (if installed)
should be plugged with the included aluminum fuel line
plug and will conveniently fi t into the fi ll line clip. Be sure to
replace the fuel line plug after fi lling or draining the fuel tank.
The pressure line will be installed onto the muffl er after the
cowl installation section.

16. Seal up the electric cooling hole cutout with thick CA
or epoxy.
Brushless Motor Installation
The Eagle 580 Matt Chapman .46-.81/EP ARF is designed
to be fl own with a .46 to .61 two-stroke glow engine, .52 to
.81 four-stroke glow engine, or a brushless out-runner motor.
If you have installed a glow engine, skip this section as it only
contains information relevant to installing a brushless motor.
Be sure to read and understand the instructions that come
with the ESC and motor before attempting to operate the
system. Also read the lithium battery handling and usage
warning on page 26 of this manual.

1. In order to achieve the required distance from the
fi rewall to the face of the bolt-on prop adapter, the ends of
the motor mount halves must be cut shorter. A hacksaw
or rotary tool with a cutoff wheel work well for this. The aft
motor mount half must be shortened by 7/8" [22mm] and
the forward motor mount half must be shortened by 1/2"
[13mm]. Reassemble the motor mount using threadlocking
compound on the mount screws.
