The Northrop F-20 Tigershark was a development of the F-5
twin-engine light fi ghter jet aircraft. The project was initiated
by a demand for exportable fi ghter jets to supply U.S. allies.
Switching over to a single engine boosted the performance
by 60%, but due to stiff competition and limited interest the
project was cancelled after only 3 prototypes were made.
Great Planes brings you this unique aircraft now in EDF
form. AeroCell
™
foam construction provides a lightweight and
durable structure that will handle everyday use. Two AIM-9
Sidewinder missiles and a display stand are included that will
allow your F-20 EDF ARF to look as great sitting on the shelf
as it does in the air. The recommended brushless motor will
allow your F-20 EDF ARF to reach speeds up to 85 mph!
For the latest technical updates or manual corrections
to the F-20 EDF ARF visit the Great Planes web site at
www.greatplanes.com. Open the “Airplanes” link, then
select the F-20 EDF ARF. 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.

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.
PROTECT YOUR MODEL, YOURSELF
& OTHERS....FOLLOW THESE
IMPORTANT SAFETY PRECAUTIONS
1. Your F-20 EDF 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 F-20 EDF ARF, 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 good condition,
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.
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.
