SAFETY PRECAUTIONS
Protect Your Model, Yourself & Others…
Follow These Important Safety Precautions
1. Your Dirty Birdy .60 ARF should not be considered a toy,
but rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Dirty Birdy, if not assembled and operated
correctly, could possibly cause injury to yourself or spectators
and damage to property.
2. You must assemble the model
according to the instructions
.
Do not alter or modify the model, as doing so may result in an
unsafe or unfl yable model. In a few cases the instructions may
differ slightly from the photos. In those instances the written
instructions should be considered as correct.
3. You must take time to
build straight, true
and
strong
.
4. You must use an R/C radio system that is in fi rst-class
condition, and a correctly sized engine and components (fuel
tank, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air.
6. You must check the operation of the model before
every
fl ight to ensure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not fl own this type
of model before, we recommend that you get the assistance
of an experienced pilot in your R/C club for your fi rst fl ights.
If you’re not a member of a club, your local hobby shop has
information about clubs in your area whose membership
includes experienced pilots.
8. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, such
as racing, or if an engine larger than one in the recommended
range is used, the modeler is responsible for taking steps to
reinforce the high stress points and/or substituting hardware
more suitable for the increased stress.

WARNING:
The fuselage and cowl included in this kit
are made of fi berglass, the fi bers of which may cause eye,
skin and respiratory tract irritation. Never blow into a part to
remove fi berglass dust, as the dust will blow back into your
eyes. Always wear safety goggles, a particle mask and rubber
gloves when grinding, drilling and sanding fi berglass parts.
Vacuum the parts and the work area thoroughly after working
with fi berglass parts.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
DECISIONS YOU MUST MAKE
This is a partial list of items required to fi nish the Dirty Birdy
ARF that may require planning or decision making before
starting to build. Order numbers are provided in parentheses.
Radio Equipment
The Dirty Birdy requires a minimum 4-channel radio system
with a minimum of fi ve 44 oz.-in. [3.2 kg-cm] standard sized
servos. If you are installing mechanical retracts, two retract
servos are also required. If you are installing pneumatic retracts,
one additional standard servo is required.
In addition, two 12" [305mm] servo extensions are required for
the aileron servos. If you are using a radio system that does
not support mixing functions, a Y-harness will also be required
to connect the aileron servos to the receiver. If you plan to
connect the aileron servos to separate channels, you will also
need two 6" [152mm] servo extensions to connect directly to
the receiver to provide easy access when mounting the wing
(these are not needed if you will be using the Y-harness).
Another Y-harness will also be needed if you are installing
mechanical retracts. There is no advantage in connecting the
retract servos to separate channels because you cannot alter
the endpoints or travel volume.
