5. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
6. Always check hardware and assembled parts after assembling. All connections should be
tight and hardware tightened.
7. Dress properly. Wear restrictive hair covering to contain long hair.
8. Use eye protection. Always wear ANSI approved impact safety goggles when assembling and
using this product.
9. Use the right Airplane and components. There are certain applications for which this
Airplane was designed. Do not modify this Airplane and do not use this Airplane for a purpose
for which it was not intended.
10. Do not use or assemble the Airplane if under the influence of alcohol or drugs. Read
warning labels on prescriptions to determine if your judgement or reflexes are impaired while
taking drugs. If there is any doubt, do not assemble or use the Airplane.
11. Do not pick up the Airplane while it is in motion.
12. Use only Batteries of the type recommended.
13. Do not mix old and new batteries.
14. Remove batteries if the Airplane is not used for a long period of time.
15. Make certain to use the Airplane in a large area free from interference from trees,
electrical power lines and other obstacles. If two airplanes with the same frequency are
used (both with the same numbers on the transmitter and/or receiver) they must be at
least 1640 feet away from one another.
16. Never fly near buildings, cars or busy streets.
17. Do not fly the Airplane at or near other people or animals.
18. Keep this product away from small children; small parts can be easily swallowed.

Landing Gear Assembly
1. Push Landing Gear (6) into the slot located under the front of the Fuselage (2a) - see Figure 2.
2. Insert the Landing Gear Brace (15) into the Fuselage (2a) at the center of the Landing Gear
(6). The Brace (15) has a tab that fits only one way into the Fuselage - see Figure 2, inset.
Battery Charging
1. Plug the Battery Pack (13) into the Charger (12). Plug the Charger (12) into a 120V
electrical outlet. Allow up to three hours for the initial charge. Do not leave unattended
when charging. Disconnect the Battery Pack (13) from the Charger (12) when the charge is
complete-see Figure 4. The batteries will become warm when they are ready for use. If you
feel them becoming overly hot, immediately disconnect the Charger (12).
2. Make certain that the “ON/OFF” Switch for the Airplane is in the “OFF” position. Plug the
Battery Pack (13) into the socket located underneath the Canopy (3). Insert the battery Pack
(13) into the Fuselage (2a) and close the Canopy (3).
3. Remove cover and insert eight “AA” batteries (not included) into the Remote Control (10).
Switch “ON” the “ON/ OFF” Switch on the Remote Control (10).
Wing, Motor and Propeller Assembly
1. Remove the Screws (8) on the Motor Housings (7). Remove the Motor Housings.
2. Attach the Main Wing (1a) to the Fuselage (2a) and thread in Screws (14) - see Figure 1.
3. Insert Motor (5) into each Motor Housing (7). Put the Motor Housing back together again
and replace the Screws (8). Make certain that the assembly is secured and that the Motors
(5) are tightly in place. Make sure that wiring is inside fuselage and does not get pinched
inside any connections or interfere with the proper fit of any parts.
4. Locate both Propellers (4). Place each Propeller (4) onto the shaft of each Motor (5).
5. Set the Tail Wing (1b) into the Tail Wing Bracket (refer to page 4). Place the Tail Wing
Support Brace (19) on top of the Tail Wing (1b) then insert two Screws (18) through the Tail
Wing Support Brace (19) and the Tail Wing (1b) then screw them in.
Set out all parts on a clear and level surface prior to assembly.

Setting up The Controls
1. Tie the Ribbon (17) to the end of the antenna, as shown in Figure 3.
2. Make certain that your hands are clear of the Propellers and any moving parts. Turn on the
switch on the Airplane.
3. If both trims are adjusted properly, the Propellers (4) should be still when the Airplane is initially
turned “ON”.
4. Each control stick has a Trim Adjustment next to it, as shown to the right.
This is used to fine-tune the neutral position of the control.
5. Pulling downward on the left hand control stick (see Figure 3) will cause
the Propellers (4) to spin faster. Returning the left hand control stick to the
center position should stop both Propellers (4) from spinning if both trims
are adjusted correctly.
6. If neither of the Propellers stop spinning when the left hand control stick
is in the center position, you will have to adjust the left hand trim slowly,
just until one of the propellers stop. The propellers should start spinning
when the control stick is moved even slightly, if not then the left hand trim
is adjusted too far.
7. The right hand control stick controls the left and right Propellers (4). Move the control stick
right to speed up the left Propeller (4), turning right; and left to speed up the right Propeller
(4), turning left. When the control stick is in the center position, neither Propeller (4) should be
spinning.
8. If one of the propellers still spins while both sticks are released, then adjust the right hand trim
until both propellers are stationary. If the left hand trim was not adjusted properly, the propellers
may still spin and steps 5-7 should be repeated until the controls operate the plane reliably.
9. Practice these steps until you are comfortable activating the Propellers (4).
10. To steer the Airplane, move the right hand control stick to the left to steer to the left, and right to
steer it right. Move the right hand control stick slightly to adjust for minor changes in direction
and tilt of the Airplane.
11. The reverse toggles can be used to reverse the operation of each of the control sticks. Each
reverse toggle controls the Control Stick nearest it. There are two settings: “N”=Normal
Operation; “R”=Reversed Controls (left=right, forward=backward, and vice-versa).

Operating and Flying the Airplane
1. Choose a day when the wind is light. The Ribbon (17) attached to the Remote Control antenna
should be blowing slightly (not greater than 30 degrees) and not be blowing straight out. Find
a wide-open field.
2. Face the Airplane into the wind. Move the left hand control stick all the way down so that both
motors are running at full power.
Note: It is recommended that two people work together to hand launch the Airplane. One
should control the Remote Control and one will launch the Airplane.
3. With the Airplane tilted at about 10 degrees, propel and release it into the wind.
4. Let the Airplane climb to and fly at about 50 to 300 feet high. By moving the right and left
control sticks you can change speed and direction.
5. If the Airplane rises too slowly, or dives, it indicates that the Nose is too tight. Adjust for this
by tightening the front Tail Wing Screw and loosening the rear Tail Wing Screw.
6. To steer the Airplane, move the right transmitter control stick to the left to steer to the left, and
right to steer it right. Move the right control stick slightly to adjust for minor changes in direction
and tilt of the Airplane.
7. If the Airplane continues to fly to far right or to far left, correct for it by moving the right transmitter
control the opposite direction. If flying left, move the control right. If flying right, move the control
left.
If adjusting the right control does not work, land the Airplane and adjust the Rudder on the
side it is leaning toward. If leaning left, adjust the left Rudder up slightly. If tilting right, move
the right Rudder up slightly.
8. Note that letting go of the control sticks will automatically bring them to a center position. This
will cause the Airplane to glide, unpowered.
9. Normal flight time for one full charge is about twenty (20) minutes. If the plane appears to be
losing power or climbs with difficulty, the batteries are low. Land the plane.
10. When the remote control’s battery begins to reach the end of its power, the red indicator light will
blink or it will make a warning noise. When this occurs, IMMEDIATELY LANDTHE AIRPLANE.
If the remote control’s battery is allowed to die completely, the plane will be uncontrolled
and may cause damage to property or SEVERE PERSONAL INJURY.
11. To bring in the Airplane for landing, glide the Airplane down against the wind. Move the left
control stick toward the center to slow the Propellers (4). Move the right control stick to adjust
for direction. Continue to decrease the Propeller (4) speed and direction until you bring them
to a stop and land the Airplane. If airplane descends too quickly, press slightly harder on the
left control stick to compensate.
