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 (see picture below: A=A’).

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.

Cut away only the covering both side

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.

Pull the left and right elevator out of the horizontal stabilizer.

Using a sharp hobby knife, carefully cut away the covering around of all slots for the horizontal stabilizer and vertical fin installation.

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 .

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.
