Dynaflite DYFA2018 - Manual (Page 5)

•Whenever the instructions tell you to glue
pieces together, thin CA should be used.
When a specific type of glue is required,
the instructions will state the type of glue
that is highly recommended. When 30-minute
epoxy is specified, it is highly recommended
that you use only 30-minute (or slower)
epoxy because you will need either the
working time and/or the additional strength.
• Do not throw away any leftover material
until after you have completed your model.
Some small pieces of leftover balsa or
plywood are used during construction.
ADHESIVES
This kit is built with three types of glue.
Cyanoacrylate - CA glues cure almost instantly
and are moderately strong. There are three
common types used: thin, medium and thick.
Thin CA cures the fastest but will not span gaps
between parts. Medium and thick CA are used
where parts do not fit perfectly. CA glue does
not bond well to most plywoods and
hardwoods. CA glues are also brittle. When
using CA glues we recommend keeping a bottle
of CA debonder on your building table.
Aliphatic Resin - Resin glues require that
parts be pinned or clamped together while the
glue dries - typically 15 to 30 minutes. Resin
glues are very strong and work well with balsa
and plywoods.
Epoxy - Six minute epoxy cures the fastest; it
sets within six minutes but is not fully cured for
one hour or more. Thirty minute epoxy is the
strongest as it allows the epoxy to soak into the
wood thoroughly. While it sets within 30 minutes,
it is not fully cured for two or more hours.
Airfoil: A curved structure designed to create
lift by the reaction to air moving over its surface.
C.G. (Center of Gravity): This is the point at
which the model balances forward and aft and
side-to-side.
Clevis: A small clip which is threaded onto the
wire end of a pushrod and connects the
pushrod to the control horn of a control surface.
The threads allow fine adjustment of the
pushrods' length.
Control Horn: The arm which is attached to a
control surface at the hingeline and is
connected to a pushrod.
Die-cut Parts: Precut parts stamped out of a
sheet of wood. The parts require a minimum of
preparation.
Dihedral: The V-shaped bend in the wing.
Typically more dihedral causes more aerodynamic
stability in an airplane, and causes the rudder to
control both the roll and yaw axis.
Doubler: Part of the structure that is laminated
to another part to increase its strength.
Elevator: The hinged control surface located at
the trailing edge of the horizontal stabilizer,
which provides control of the model about the
pitch axis and causes the model to climb or
dive. The correct direction of control is to pull
the transmitter elevator control stick back,
towards the bottom of the transmitter, to move
the elevator upward, which causes the airplane
to climb and vice versa to dive.
Foam Rubber: A soft foam material used to
wrap the receiver and receiver battery for
protection.
