INTRODUCTION
Congratulations and thank you for purchasing the Kunai. The 
Kunai’s versatility makes it one of those models that everybody 
should own! It can be fl own like a glider, like an aerobatic 
plane, like a hotliner or even like a pylon racer. When you
put the pedal to the metal the Kunai’s light weight, thin wing
and clean lines allow it to reach warp speed right away! And 
when you cut the throttle the prop folds back and the Kunai 
conserves energy, allowing thrilling, power-off fl y-bys with the 
only sound the whoosh of air as the Kunai silently speeds by. 
And if you dump the spoilerons the Kunai slows to a crawl for
thermal seeking and easy, feather-light landings.
For the latest technical updates or manual corrections to the 
Kunai visit the Great Planes web site at www.greatplanes.com. 
Open the “Airplanes” link, then select the Kunai. If there is 
new technical information or changes to this model a “tech 
notice” box will appear in the upper left corner of the page.

AMA is the governing body of model aviation and membership
provides liability insurance coverage, protects modelers’ rights 
and interests and is required to fl y at most R/C sites:

IMPORTANT!!! Two of the most important things you can 
do to preserve the radio controlled aircraft hobby are to avoid 
fl ying near full-scale aircraft and avoid fl ying near or over 
groups of people.
SAFETY PRECAUTIONS
Protect Your Model, Yourself & Others…
Follow These Important Safety Precautions
1. Your Kunai 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 Kunai, 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 use an R/C radio system that is in good condition, 
a correctly sized motor, 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.
4. While this kit has been fl ight tested to exceed normal use,
if the plane will be used for extremely high stress fl ying, or if 
a motor 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.
5. WARNING: The fuselage pod and boom included in this 
kit are made of fi berglass or carbon fi ber, 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 representa-
tions 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.
ADDITIONAL ITEMS REQUIRED
The chart on page 3 lists the electronic items recommended to
fi nish the Kunai. The Futaba receivers listed are recommended 
because the servos plug into the end of the receiver making 
it the best fi t (receivers with “top plug” receptacles may not fi t).
Also note that a Y-connector (included) may be used for the
aileron servos, but this will eliminate the optoin of spoilerons.
