2)Removeeachhingefromthewingpanel

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

each hinge. Slide each hinge into the wing

panel until the T-pin is snug against the wing

panel. This will help ensure an equal amount

ofhingeisoneithersideofthehingelinewhen

the aileron is mounted to the aileron.

The control surfaces, including the

ailerons, elevators, and rudder, are

prehinged with hinges installed, but the

hinges are not glued in place. It is

imperativethat you properly adherethe

hingesin place perthesteps that follow

using a high-quality thin C/A glue.

Note:

HINGING THE AILERONS.

3) Slide the wing panel on the aileron 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

shouldbemaintained between the wingpanel

andaileron.

1) Carefully remove the aileron from one

of the wing panels. Note the position of the

hinges.

TURBO RAVEN. Instruction Manual

8)After both ailerons aresecurely hinged,

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.

7) Repeat this process with the other wing

panel, securely hinging the aileron in place.

Work the aileron up and down several

times to “work in” the hinges and check

for proper movement.

Note:

4)Deflect the aileron and completely

saturate each hinge with thin C/A glue. The

aileronsfrontsurfaceshouldlightlycontactthe

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.

Note: The hinge is constructed of a special

material that allows the C/A to wick or

penetrateanddistributethroughoutthe

hinge, securely bonding it to the wood

structureofthe wing panel andaileron.

5)Turn the wing panelover anddeflectthe

aileron in the opposite direction from the

opposite side. Apply thin C/A glue to each

hinge,making surethattheC/Apenetrates into

both the aileron and wing panel.

6) Using C/A remover/debonder and a

papertowel,remove any excess C/A gluethat

may have accumulated on the wing or in the

aileronhinge area.

2) Position the control horn on the bottom of

the aileron. You will see pre-drill hole 3mm for

the horn mounting screw on the aileron.

3) Place epoxy into hole. This will harden the

threads and prevent the crews from pulling

loose.

4) Thread a control horn end with aluminum

washer, lock nut until the top edge of the end is

18mm from the vase of the horn as shown.

Install the elevator control horn using the

same method as same as the aileron control

horns.

use threadlock on the screws to help prevent

them from vibrating loose.

3) Carefully bend the second nylon tube

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

1) Using a modeling knife, carefully cut

off the rear portion of one of the 3 nylon tubes

leaving 1/2” protruding from the rear of the

stopper. This will be the fuel pick up tube.

tothe weighted fuel pickup and the other end

to the nylon pick up tube.(The silicon tube is

not included).

TURBO RAVEN. Instruction Manual

5) With the stopper assembly in place,

the weighted pick-up should rest away from

therear ofthe tank and move freelyinside 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.

FUEL TANK INSTALLATION.

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 the tank is installed inside the fuselage,

it may be difficult to determine which is which.

Fuel pick-up tube. Fuelfill tube.

Vent tube.

Blow through one of the lines to ensure

thefuel lines have not become kinked in-

side the fuel tank compartment. Air should

flowthrough easily.

Balsa wood included.

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.

Important: When the stopper assembly is in-

stalled in the tank, the top of the vent tube

should rest just below the top surface of the

tank. It should not touch the top of the tank.

Carefully use a lighter or heat gun to

permenently set the angle of the vent tube.

 8) Use balsa stick to help prevent moveable

from transferring to the fuel tank.

 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.

 7) Slide the fuel tank into the fuselage.

Guide the lines from the tank through the hole

in the firewall.

the notch of the wheel pant as shown.

6) Slide the threaded end of the axle

through the hole in the bottom of the landing

gear leg. Use a washer and locknut to tighten

the axle to the landing gear. Make sure to use

threadlock on the nut so it won’t vibrate loose

in flight as shown.
