Dress properly7. . Wear restrictive hair covering to contain long hair.
Wear ANSI-approved impact safety goggles when using and assembling this product.8.
Maintain products with care9. . Keep the Biplane in a dry location. Do not expose it to pro-
longed moisture.
Use the right Biplane for the job.10. Do not attempt to force a small Biplane to do the work of
a larger Biplane. There are certain applications for which this Biplane was designed. Do not
modify this Biplane and do not use this Biplane for a purpose for which it was not intended.
Do not use or assemble the Biplane11. if under the inuence of alcohol or drugs. Read
warning labels on prescriptions to determine if your judgement or reexes are impaired while
taking drugs. If there is any doubt, do not assemble or use the Biplane.
Do not pick up the Biplane while it is in motion.12.
Use only batteries of the type recommended.13.
Do not mix old and new batteries and remove batteries if the Biplane is not used14. for a long period of time.
Do not recharge non-rechargeable batteries.15.
Use the Biplane in a large area free from interference from trees, electrical pow-16. er lines and other obstacles.
Do not y near buildings, cars, busy streets or at other people or animals.17.
Do not y the Biplane if wind speeds are above 10 MPH.18.
Do not allow children to use glue without adult supervision.19. Store glue out of
reach of children and animals.
If two airplanes with the same frequency are used (both with the same numbers20. on the transmitter and/or receiver) they must be at least 1,640 feet away from
one another.
Before ying, perform a distance check to be certain that you can maintain radio 21. control at least 25 feet from the transmitter to the Biplane with the antenna col-
lapsed.
Do not trim the Biplane’s antenna.22. Trimming the antenna will affect radio range.
People with pacemakers should consult their physician(s) before use.23. Electro-
magnetic elds in close proximity to heart pacemaker could cause pacemaker interfer-
ence or pacemaker failure.
The warnings, cautions, and instructions discussed in this instruction manual cannot cover all24. possible conditions and situations that may occur. It must be understood by the operator that

2. Plug the Battery Pack (4) into the outlet located on the Biplane as seen in Figure 1.
Please note: The Battery Pack is installed from the rear by sliding it forward until it3. rests against the lip/stop on the airframe, as seen in Figure 2. Once installed, the Bat-
tery Pack should be locked into place by inserting the rubber pin through the holes in
the battery tray and airframe.
Charging the Battery Pack
The Battery Pack (4) is charged from the Transmitter/Charger Unit (2). Place the bat-1.
tery on a reproof surface and plug the Battery Pack (4) into the Charging jack, locat-
ed at the side of the Transmitter/Charger Unit (2)-see Figure 3.
Hold down the red button until the battery indicator turns orange.2.
A charge time of three to ve minutes is usually sufcient.3.
During charging the Battery Pack will get warm. Make certain it does not get overly4. hot.
The Battery Pack must have three to four initial charges of a longer duration before5. they obtain a full run time of 4 to 6 minutes.

Operating the Radio Transmitter
The Transmitter uses 8 “AA” batteries (not included). Remove the Battery Compart-1. ment Cover (12)-see Figure 4. Insert the batteries into the Battery Compartment mak-
ing certain to line up the batteries with the polarity indicated in the Battery Compart-
ment. Press the Battery Compartment Cover (12) back into place.
The Radio Transmitter (2) transmits a signal to the airplane’s receiver.2.
The Radio Transmitter (2) has a LED display that will light up when the Transmitter is3. on. The LED readout will indicate the strength of the battery charge:
Green• indicates the batteries are at full capacity
Yellow• indicates the batteries are at half capacity
Red• indicates the batteries need replacing
The Radio Transmitter/Charger is turned ON and OFF with the On/Off Switch located4. midway between the Control Sticks-see Figure 4.
The Radio Transmitter/Charger has two Control Sticks.5.
The Control Stick located on the left moves vertically and controls the Climb. Push• the Climb Control Stick forward to turn on the twin motors and cause the Biplane to
climb. Pull back on the Climb Control Stick to slow down the twin motors and cause
the Biplane to lower altitude-see Figure 4.
The Control Stick located on the right moves horizontally and controls the direction• of the Biplane. Pushing the Turn Control Stick right or left causes the Biplane to turn
right or left.
Attach the Wind Ribbon to the Radio Transmitter Antenna.6.
Installing Propellers
Turn the Radio Transmitter off and unplug the Battery Pack.1.
The Biplane comes with spare Propellers. If necessary, remove the Nut holding each2. Propeller in place. Remove the Propeller. Install new Propeller.

OPERATION
Choose a day when the wind is light.1. The ribbon attached to the Radio Transmitter
antenna should be blowing slightly (not greater than 30 degrees) and not be blowing
straight out. Find a wide-open eld.
Turn ON the Radio Transmitter.2.
Face the Biplane into the wind. Move the left hand control stick all the way forward so3. both motors are running at full power.
Note: It is recommended that two people work together to hand launch the Biplane. One
should control the Remote Control and one will launch the Biplane.
With the Biplane tilted at about 10 degrees, propel and release it into the wind.4.
Let the Biplane climb to and y at about 50 to 300 feet high. By moving the Climb 5. and Turn control sticks you can change speed and direction.
To steer the Biplane, move the right Turn control stick to the left to steer to the left, and6. right to steer it right. Move the Turn Control Stick slightly to adjust for minor changes
in direction and tilt of the Biplane.
Note: Letting go of the control sticks will automatically bring them to a center position. This
will cause the Biplane to resume normal ight.
Normal ight time for one full charge is about four to six minutes. When the battery 7. begins to reach the end of its power, the red LED light on the Radio Transmitter will
light up, indicating low transmitter power. When this occurs, IMMEDIATELY LAND
THE BIPLANE.
To bring in the Biplane for landing, glide the Biplane down against the wind. Move the8. left Climb control stick toward the center to slow the Propellers. Move the right Turn
control stick to adjust for direction. Continue to decrease the Propeller speed and
direction until the biplane lands and the propellers stop.
Turn OFF the Radio Transmitter.9.
Important: If damage is caused due to a crash; your warranty is void.

Do not use solvents or liquid cleaners to clean the Biplane. Use of solvents or liquid3. cleaners will damage the product. Use only a dry, soft cloth for cleaning.
Before each use check for loose screws, misalignment or binding of moving parts,4. cracked or broken parts, damaged housing, damaged wiring, loose wheels and any
other condition that may affect its safe operation. If abnormal noise or vibration oc-
curs, have the problem corrected before further use. Do not use the Biplane if it is
damaged.
Do not leave the Biplane outside as prolonged exposure to the elements will damage5. the exterior of the Biplane.
