ADHESIVES & GLUING TECHNIQUES

CA adhesives are specially formulated to firmly glue the

plywood, hardwood, and balsa used in your model and to

withstand the vibration and stresses of high performance

flight. However, there are times, such as when you are

installing the stabilizer and fin on the fuselage and want

more set-up time for careful alignment and positioning,

then you should use epoxy. Occasionally, you also will

want to use thin CA, which "wicks" into the surrounding

areas. Aliphatic resin glue or similar water-based glues can

also be used, but they will add to the assembly time

because they dry so much more slowly than CA glue.

Remember, when ever using any CA, you must be careful

to read instructions thoroughly, as you will have only sec-

onds for positioning of parts. Be sure to trial fit parts

together before gluing. Also, never use watery THIN type

CA glue for gluing plywood and hardwood parts. Thin CA's

do not adequately bond these areas.

CAUTION

Some people may experience an allergic reaction when

exposed to fumes from CA glue or epoxy. As with paints,

thinners, and solvents, it is always important to use glues

only where there is adequate ventilation to carry fumes

away. A fan is recommended. Also, special care must be

taken when using CA, as it will bond skin as well as other

surfaces. Before using any CA, carefully read all label pre-

cautions. When using CA, protective eye-wear and care in

keeping the glue away from the face is highly recommend-

ed. If CA does happen to get into the eye, hold lid open

and flush with water only. Seek immediate medical atten-

tion.

PREPARING FOR ASSEMBLY

You will need a work area of approximately 24 x 48" which has

been covered to protect it from adhesive, as well as cuts and

other damage. Many people cover their work area with a

sheet of dry wall (sheet rock) and/or waxed paper t o pre-

vent CA Glue and Epoxy from ruining the work surface.

CONSTRUCTION TIPS

IMPORTANT: ALWAYS READ A FEW STEPS AHEAD.

This will alert you to coming instructions and will help you

plan accordingly.

Using the Parts Identification section, familiarize yourself

with the various items included in your kit box.

COVERING

The E

xttrra

a 3

ARF is covered in a premium polyester film

chosen by many of the world's top flyers for its beauty,

toughness, and ease of application and repair. It is not

uncommon for ARF's to develop a few wrinkles in transit.

If this is true of your model, the situation is easily correct-

ed. Before you begin putting the pieces together, run

around the edge of the seams first then over the surface

of each section with an iron (either specially designed for

airplane use or the more cumbersome household iron).

Apply the heat (set at about 350° F), following along with

a soft cloth and pressing down on the covering as you go

around. This will more firmly set the covering adhesive

into the wood and keep your aircraft covering tight and

smooth in the future. Once you have ironed the seams

stay away from them with the heat or the covering will

slide when you try to shrink the middle. If this happens the

wrinkles will not come out of the covering.
