Freewing F-104 Starfighter User Manual

The famous Lockheed F-104 Starfighter has been recreated in this amazing 90 mm EDF jet. Following up on their
popular 70 mm variant, Freewing has answered the customer demands for a 90mm Super Scale version of this iconic jet
fighter.

Co-presented by SebArt and Freewing, the F-104 Starfighter 90 mm EDF jet is constructed with EPO foam,
with a wingspan of 755mm and a length of 1720mm and is available in two different color schemes. The silver color
scheme of the George Air Force Base's 479th Tactical Fighter Wing FG-907, and the yellow/black Italian Air Force 82th
anniversary paint scheme .

Other than some small adjustments in main wing and horizontal stabilizer shape, to increase its flight stability,
we have replicated the original shape of the F-104 as well as using a scale afterburner, warning lights and landing lights to
make the airplane more realistic looking during flight. The aluminum shock absorbing landing gear incorporates an electric
worm controller to effectively reduce the impact on landing . Fiberglass material is incorporated to make the nose and
main landing gear doors lighter to reduce weight as well as reduce its wind resistance during flight. A specially designed
air-brake will allow more airflow during flight, and help reduce landing speed. All this In addition to the many scale details
such as the scale pilot, instrumentation sticker, pitot tube…etc.

The main wing, horizontal stabilizer, vertical stabilizer all can be easily removed for transport. In order to enhance
the overall strength, several carbon tubes are located in the main wing, horizontal and vertical stabilizers as well as 2x16g
metal gear servos, 7x17g metal servos and 3x9g metal servos all using ball link connectors to increase flight stability.
The pre-installed 90mm 12-blade ducted fan with 3748-1550KV brushless motor and Hobbywing 130A (8A UBEC) ESC
gives it a great sound combined with powerful thrust and the use of a control board creates a less cluttered battery
compartment .

The 90mm F104S “Starfighter” comes with a Freewing 3-axis Gyro (E51) pre-installed to further increase its
flight stability. During flight, its excellent speed and climb performance can easily emulate conventional tactical
flight maneuvers. With the F104's special aerodynamic shape, a long glide path with the air speed brakes and
about 30 degrees elevation angle is needed to decelerate for landing.

3. Freewing and it's vendors will not be held responsible for any losses due to improper assembly and operation.

4. Model airplane operators must be at least 14 years of age.

5. This airplane is made of EPO foam material, covered with surface spray paint. Don't use chemicals to clean as it may
cause damage.

6. You should avoid flying in areas such as public places, areas with high voltage power lines, nearby highways, airports
or in other areas where laws and regulations clearly prohibit flight.

7. Do not fly in bad weather conditions, including thunderstorms, snow, etc...

8. Lipo batteries should be properly stored in a fire proof container and be kept at a minimum of 2M distance away from
flammable or explosive materials.

9. Damaged or scrap batteries must be properly discharged before disposal or recycling to avoid spontaneous
combustion and fire.

10. At the Flying Field, properly dispose of any waste you have created, don't leave or burn your waste.. Ensure that
your throttle is in the low position and that your radio is turned on before connecting the Lipo battery.

11. Ensure that the throttle is in the lowest position and transmitter is turned on, before connecting a Lipo Battery to
the ESC of the aircraft.

12. Do not try to catch the airplane while in flight or during landing. Wait for the airplane to come to a complete stop
before handling.
