ADJUSTING THE AILERON LINKAGE
q
17) With your radio system plugged in and
turned on, check the control surface direction and
amount of deflection in each aileron. Push the aile-
ron control stick all the way to the right. The aileron
on the right wing half should move up and the aile-
ron on the left wing half should move down (looking
from the back of the wing with the wing right side
up). If they don't, move the servo reversing switch
on your transmitter. This will change the direction
(refer to your radio instructions for more informa-
tion on this function).
q
18) Push the aileron control stick all the way to
the right. Using a ruler, measure the amount the trail-
ing edge of each aileron moves. This measurement
should be 1/4”. See figure # 12 below.
q
19) If the aileron control surface deflection is
more or less than 1/4” it must be changed. If your
radio is equipped with digital or manual end point
adjustments, make those adjustments using the trans-
mitter. If your radio does not have this feature, you
can adjust the control horns or servo arm. If the aile-
rons are moving more than 1/4” you can move the
pushrods in one hole toward the center of the servo
arm. If the ailerons are moving less than 1/4” you
can thread the adjustable connectors down further.
When adjusted properly, both ailerons should move
1/4” both up and down.

FINAL ASSEMBLY
INSTALLING THE FUEL LINES
q
1) Using a modeling knife, cut each of the two
fuel lines to the proper length and attach them to the
engine. The vent/pressure line connects to the pres-
sure nipple on the muffler. The fuel pickup line
connects to the fuel nipple on the carburetor.
When attaching the vent/pressure line to the
muffler, make sure you leave enough slack in
the tubing to prevent it from pinching closed.
q
2) To fill the fuel tank, remove the fuel lines
from both the carburetor and the muffler. Fill through
the fuel pickup line and watch for excess fuel com-
ing from the vent line. When fuel begins to come out
of the vent line, the fuel tank is full. Reattach the
fuel lines to their proper locations.
INSTALLING THE SWITCH
q
3) The switch should be mounted on the left side
of the fuselage, in the forward section of the servo
compartment. Locate the switch 5-1/2” behind the
firewall and 1-1/8” down from the wing saddle. Use
the faceplate of the switch itself to locate and mark
the switch cutout and mounting holes.
q
4) Cut out the switch hole using a modeling
knife. Use a 5/64” drill bit to drill the two mounting
holes through the fuselage side.
q
5) Secure the switch in place using the two ma-
chine screws provided with the switch. Do not
overtighten the screws. You don't want to crush the
wood. See photo # 32 below.

INSTALLING THE BATTERY AND RECEIVER
q
6) Using a pair of scissors, cut out a piece of
Dubro Foam Rubber and wrap it around your receiver
battery pack. Use a couple of long pieces of mask-
ing tape, wrapped around the pack, to hold the foam
in place. See photo # 33 below.
