The control surfaces, including the

ailerons, elevators, and rudder, are

prehinged with hinges installed, but

the hinges are not glued in place. It

is imperative that you properly

adhere the hinges in place per the

steps that follow using a high-quality

thin C/A glue.

2)Removeeach hinge fromthewingpanel

and aileron and place a T-pin in the center of

each hinge. Slide each hinge into the aileron

untiltheT-pin is snugagainst theaileron.This

will help ensure an equal amount of hinge is

oneithersideofthehingelinewhenthe aileron

is mounted to the wing panel.

Note:

1) Carefully remove the aileron from one

of the wing panels. Note the position of the

hinges.

HINGING THEAILERON .

3) Slide the aileron on the wing panel until

there is only a slight gap. The hinge is now

centered on the wing panel and aileron.

Remove the T-pins and snug the aileron

against the wing panel.A gap of 1/64” or less

shouldbe maintained betweenthe wing panel

andaileron.

8)Afterbothailerons are securelyhinged,

firmly grasp the wing panel and aileron to

make sure the hinges are securely glued and

cannot be pulled out. Do this by carefully

applying medium pressure, trying to separate

the aileron from the wing panel. Use caution

not to crush the wing structure.

Workthe aileron up and down several

times to “work in” the hinges and

check for proper movement.

Note:

HINGING THE ELEVATOR.

Glue the rudder hinges in place using the

same techniques used to hinge the ailerons.

4) Deflect the aileron and completely

saturate each hinge with thin C/A glue. The

aileronsfrontsurface should lightlycontact the

wing during this procedure. Ideally, when the

hinges are glued in place, a 1/64” gap or less

will be maintained throughout the lengh of the

aileron to the wing panel hinge line.

Thehingeisconstructed of a special

material that allows the C/A to wick

or penetrate and distribute

throughout the hinge, securely

bonding it to the wood structure of

the wing panel and aileron.

may have accumulated on the wing or in the

5) With the stopper assembly in place,

the weighted pick-up should rest away from

therear of the tank and move freely inside the

tank. The top of the vent tube should rest just

below the top of the tank. It should not touch

the top of the tank.

6) When satisfied with the alignment of

the stopper assembly tighten the 3 x 20mm

machine screw until the rubber stopper ex-

pands and seals the tank opening. Do not

overtighten the assembly as this could cause

the tank to split.

3) Carefully bend the second nylon tube

up at a 45º angle. This tube is the vent tube.

4) Test fit the stopper assembly into the

tank. It may be necessary to remove some of

the flashing around the tank opening using a

modeling knife. If flashing is present, make

sure none falls into the tank.

You should mark which tube is the vent

and which is the fuel pickup when you attach

fuel tubing to the tubes in the stopper. Once

thetank isinstalledinside thefuselage, it may

be difficult to determine which is which.

FUEL TANK INSTALLATION.

 7) Slide the fuel tank into the fuselage. Guide

the lines from the tank through the hole in the

firewall.

the fuel tank with C/A glue to secure the fuel

tank inside the fuselage.

9) Connect the lines from the tank to the engine

and muffler. The vent line will connect to the

muffler and the line from the clunk to the

carburetor.

Blow through one of the lines to ensure

the fuel lines have not become kinked in-

side the fuel tank compartment. Air should

flow through easily.

Because the size of servos differ, you

mayneedtoadjustthe size ofthe precut open-

ing in the mount. The notch in the sides of the

mount allow the servo lead to pass through.

 2) Secure the servos with the screws pro-

vided with your radio system.

connector over the pushrod wire. Center the

throttle stick and trim and install the servo horn

perpendicular to the servo center line.

9) Move the throttle stick to the closed position

and move the carburetor to closed. Use a 2.5mm

hex wrench to tighten the screw that secures

the throttle pushrod wire. Make sure to use

threadlock on the screw so it does not vibrate

loose.
