WARNING! This radio controlled model is NOT a toy. If modified or flown carelessly it could go out of controll and

cause serious human injury or property damage. Before flying your airplane, ensure the air field is spacious enough.

Always fly it outdoors in safe areas and seek professional advice if you are unexperienced.

ACHTUNG! Dieses ferngesteuerte Modell ist KEIN Spielzeug! Es ist für fortgeschrittene Modellflugpiloten bestimmt,

die ausreichende Erfahrung im Umgang mit derartigen Modellen besitzen. Bei unsachgemässer Verwendung kann

hoher Personen- und/oder Sachschaden entstehen. Fragen Sie in einem Modellbauverein in Ihrer Nähe um

professionelle Unterstätzung, wenn Sie Hilfe im Bau und Betrieb benötigen. Der Zusammenbau dieses Modells ist

durch die vielen Abbildungen selbsterklärend und ist für fortgeschrittene, erfahrene Modellbauer bestimmt.

If exposed to direct sunlight and / or heat, wrinkles can appear. Storing the model in a coll

place will let the wrinkles disappear. Otherwise, remove wrinkles in covering film with a hair-

dryer, starting with low temperature. You can fix the corners by using a hot iron.

Bei Sonneneinstrahlung und / oder Warme kann die Folie erschlaffen bzw. Falten entstehen.

Verwenden Sie ein Warumluftgeblase (Haartrockner) um evtl. Falten aus der Folie zu

10- Joining the wing halves

Before gluing:

- Draw the center line on the wing joiner.

- Trial fit each part before gluing . Be certain that there are no gaps.

If the parts will join, but with a gaps, sand or trim the parts a little at

a time until the parts meet exactly with no gaps.

- Check for the correct dihedral angle

Draw the center line

on the wing joiner

L/R

Coat one half of the dihedral brace with epoxy up

to the center line. Install the epoxy-coated side of

the dihedral brace into the wing joiner cavity up to

the center line.

13- Horizontal Stabilizer installing

Cut away only

the covering

Siai Marchetti SF-260

13A

Using a sharp hobby knife, carefully cut away the covering

around of all slots for the horizontal stabilizer installation.

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

13B

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’).

Center point

AA’

A=A’

13C

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.

13D

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.

Cut away only

the covering

both sides.

Page 13

14- Horizontal Stabilizer installing continued

Siai Marchetti SF-260

Apply thin CA glue where the fuselage

meet the horizontal stabilizer (both sides).

Install the horizontal stabilizer onto the fuselage and adjust the alignment as described in steep 13B.

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.

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.

29- Balancing

Siai Marchetti SF-260

THE CENTER OF GRAVITY IS LOCATED BACK FROM

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

THE PLANE UPSIDE DOWN WITH THE FUEL TANK EMPTY.

98mm

1- Mount the wing to the fuselage. Using a couple of pieces of masking tape,

place them on the top side of the wing (98mm) back from the leading

edge, at the fuselage sides.

2- Turn the plane upside down, lift the airplane. Place your fingers on the

masking tape and carefully lift the plane.

3- If the nose of the plane falls, the plane is heavy nose. To correct this, move the battery pack further back in the fuselage.

If the tail of plane falls, the plane is tail heavy. To correct this, move the battery forward or if this is not possible, stick weight onto the

firewall.

When balanced correctly, the airplane should level or slightly nose down when you lift it up with your fingers.

LATERAL BALANCE:

After you have balanced a plane on the CG, you should laterally balance it. Doing this will help the airplane track straighter.

1- Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire.

With the wing level, carefully lift the airplane by the string. This may require two people to make easier.

2- If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side

of the lighter wing half’s wing tip. Follow this procedure until the wing stays level when you lift the airplane.

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

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 Siai Marchetti SF-260 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”.
