Using a sharp hobby knife, carefully cut away

the covering around of all slots for the horizontal

stabilizer and vertical fin installation.

Pull the left and right elevator out of the horizontal

stabilizer.

Push the horizontal stabilizer into the slot on the

fuselage as show. Check the alignment of the

horizontal stabilizer by measuring from a fixed

point along the center line of the fuselage to the

leading edge on each side of the horizontal stabilizer.

The distance must be equal on both sides .

If not, adjust the stabilizer until the measurements

are the same.

11-Horizontal stabilizer

Cut away only

Cut away only

When you are satisfied with the alignment, use

a pencil to trace around the top and bottom of

the stabilizer where it meets the fuselage.

Remove the horizontal stabilizer

from the fuselage. Using a straight edge

and a sharp hobby knife, carefully cut away

the covering inside the lines which were marked

above. Be cautious not to cut into the wood-this

will weaken the structure.

CESSNA 208

12-Horizontal stabilizer

Install the horizontal stabilizer onto the fuselage and adjust the alignment as described in section 11.

Note: it is important to ensure that the horizontal stabilizer is also level in regards to the fuselage.

Apply the thin CA along the area where the covering was removed in the previous step and to the

fuselage where the horizontal stabilizer mounts .

! Securely glue together. If coming off during fly,

you lose control of your air plane.

Apply CA glue

both sides.

(thin CA)

Apply thin CA glue into the slot where

the fuselage meet the horizontal stabilizer.

Carefully, push the vertical fin into the

slot on the fuselage as shown.

Trial fit the vertical fin in position. Using a 90 degree triangle or adjust the vertical stabilizer ensure

that the B=B’ as shown, the vertical stabilizer is perpendicular to the horizontal stabilizer.

Using a pencil, trace around the vertical stabilizer where it meets the fuselage. Remove the vertical

stabilizer from the fuselage.

Insert the vertical fin into the fuselage, precisely align

the vertical stabilizer as described in step 13A.

Apply the thin CA glue on the vertical stabilizer where it

contacts the fuselage.

Note: Cut out the stickers and apply them in the proper area. Do not peel the backing paper off all at once.

Peel off one corner of the backing and cut off with scissors.

Arrange sticker on model and when satisfied adhere the corner without backing.

Carefully peel back the rest of the backing while at the same time adhering the rest of the sticker.

Try not to make air bubbles, if there are some, carefully puncture sticker (center of bubble) but not model surface with

the tip of the knife or sharp pin and squeeze out the air.

At curves stretch sticker and apply a little heat so that no ceases occur.

Cut off the excess that is produced.

IMPORTANT: Please do not clean your model with strong solvent or pure alcohol, only use kerosene to keep the

colour of your model not fade.

30-Balance

THE CENTER OF GRAVITY IS LOCATED 65 - 68mm BACK FROM THE

LEADING EDGE OF THE WING, AT THE FUSELAGE. BALANCE A PLANE

UPSIDE DOWN WITH THE FUEL TANK EMPTY.

DO NOT try to fly an out-of-balance model !

65-68mm

CESSNA 208

IMPORTANT: Flying your model at these throws will provide you with the greatest chance for successful first flights.

If, after you have become accustomed to the way the Cessna 208 flies, you would like to change the throws to suit your taste

that is fine. However, too much control throw could make the model difficult to control, so remember, “more is not always better”.

BEFORE FLYING CHECK EVERYTHING

Before each flight, inspect the airplane for any loose parts. Check the hinges, make sure the pushrods are still firmly

attached, and check the engine mounting bolts. In general, check everything on the plane that might possibly come

loose.
