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 good condition,
a correctly sized engine, and other components as
specifi ed in this instruction manual. All components must
be correctly installed so that the model operates correctly
on the ground and in the air. You must check the operation
of the model and all components before every fl ight.
5. 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.
6. While this kit has been fl ight tested to exceed most
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.
7. WARNING: The cowl included in this kit is 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 product 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 repre-
sentations are expressed or implied as to the performance
or safety of your completed model.
NOTE: Some technically-minded modelers who wish to
check the wing, stab and motor thrust angles may do so by
visiting the web site at www.greatplanes.com and clicking
on "Technical Data."
REMEMBER: Take your time and follow the instructions
to end up with a well-built model that is straight and true.
