 7. Install the grommets and brass eyelets in the throttle
servo. Secure the servo using a #1 Phillips screwdriver and
the hardware included with the servo. Make sure to prepare
and harden the holes as described through the earlier
sections of the manual for servo installation.
 8. Attach the servo arm to the throttle servo. Install the
two ball links and the 4-40 x 1 3 /
4
-inch adjustable linkage. Use
the radio system to check the operation of the throttle servo
to make sure it operates the carburetor correctly.
 9. Slide the engine mount box into the fuselage as shown.
 10. Prepare the five cowl mounting screws using five
tapered washers, five foam disks, four 4-40 x 1/2-inch
button head screws and one 4-40 x 3/4-inch button head
screw. Note that the tapered washers will have the cone
facing out toward the head of the screw.
 11. Slide the cowl into position and secure it using the
screws prepared in the previous step. The longer 4-40 x
3/4-inch screw is used to secure the cowl at the top-center
of the cowl. Use a 5/64-inch hex wrench to tighten the cowl
mounting screws.
 12. Use a straight edge on the drive washer of the engine
to check the gap for the spinner. Adjust the position of the
engine box in the fuselage until there is a 3/32-inch (2mm)
gap between the straight edge and cowl as shown.
Note : The previous step only works when using
a spinner with a flat backplate. If the backplate
of your particular spinner will be recessed on
the driver washer, use the backplate to set the
gap between the cowl and spinner backplate.
