mentioned above.
PP-T6FN
The flaps, etc. can be operated by means
of a potentiometer, in addition to the 5
operations described above.
• Select either the long or short left and
right stick knob, whichever is the easiest
to use.
The knob can be replaced by merely pulling off the black knob.
• Hook the neckstrap to the hook and hang
the transmitter from your neck.
1. The
FP-3FN, FP-4FN, FP-5FN, FP-6FN each use a built-in nickel-cadmium battery (8/450 mAH) as the transmitter
power source.
2. Mount the antenna securely and set the power switch to the ON position . The pointer of the meter will deflect
to within the green zone. This indicates that the radio waves are being radiated. If the meter pointer fails
to
deflect, check for a faulty connection in the power supply.
3. If the meter pointer deflects to within the red zone, the nickel-cadmium battery is low and must be recharged. A special charger is provided.
4. Note that the range of the radio waves will become shorter when the meter pointer deflects to within red zone.
5. The "trim" lever of each stick is used for fine adjustment. These levers are used for neutral adjustment of each
rudder and to adjust the flying posture after mounting in the fuselage.
6. Open the stand at the rear cover when setting up the transmitter. This stand can be used as a handle by
raising it to the topmost position. This is extremely convenient when carrying the transmitter.

4. Since all the servos are manufactured to the same standards, any servo can be used for any purpose.
5. The FP-S6L (reversible servo, red label) in the set can be conveniently used for throttle control with high wing
and middle wing airframes.
6. Connection methods are illustrated in Figure 3. Be sure that each connector is plugged in fully and that the
power supply switch harness, aileron section, etc. are connected correctly.
7. After verifying that all connections are correct by checking them against the connections given in Figure 3, turn
the transmitter power switch on. Then turn the receiver switch on. At this time, each servo will stop at the
neutral position.
8. Operate sticks and trim levers and verify that respective servos operate positively.
9. When testing each section, be sure that the transmitter and receiver antennas are fully extended. If the transmitter antenna is short and the power switch is left on for more than 5 minutes, the transistors inside the
transmitter will be damaged.
10.
If the system fails to operate after the transmitter, receiver, servos, switch harness, and batteries have been
properly installed, the problem may be due to damage during shipment. Do not attempt to open any of the
unit, but return them for replacement.
FUTABA TRAINER SYSTEM
•The
NEW FUTABA PROPORTIONAL
newly developed FUTABA Trainer System as standard. This system prevents damaging of valuable aircraft by
beginners. Use this system with a veteran as your teacher. A special trainer cord is available as an option.
• The FUTABA Trainer System can be used without regard to frequency (27MHz, 40MHz, 72MHz) or number of
channels of the instructor's transmitter and students transmitter. For instance, the 27MHz FP-T6FN can be
used with the 72 MHz FP-T4FN. However, in this case, use the 27MHz FP-T6FN as the instructor's trans-
mitter if the frequency of the receiver is 27MHz and use the 72MHz FP-T4FN as the instructor's transmitter if
the frequency of the receiver is 72MHz. Naturally, the number of operable channels corresponds to that of the
transmitter. The above is an example of 4 channel operation.

OPERATING INSTRUCTIONS
1. When conducting training, connect the two transmitters together with the special cord*as illustrated in Figure 4.
*Similar cords are on sale, but since these cannot be used, always use the special FUTABA shielded trainer
cord.
2. The instructor must use a transmitter of the same band as the receiver. (The instructor's transmitter is designated
Tx1 and the student's transmitter is designated Tx2.)
Since the radio waves are always radiated from the Tx1 side (transmitter whose power has been turned on),
extend the antenna of Tx1 fully. The position of the antenna of Tx2 doesn't matter, since the radio waves are
radiated from Tx1 even when operation is performed from Tx2.
3. Turn on the power of Tx1 only. The meter pointer will deflect, the same as for the case of independent operation.
The meter pointer of Tx2 will also deflect simultaneously.
NOTE: Never turn the power switch of Tx2 on, regardless of whether the bands coincide or not.
4. When the trainer button of Tx1 is depressed,
radio waves will be directly radiated from
Tx1, but the control operation is shifted to
Tx2. Consequently, the student can exercise
control only during the period the instructor
is depressing the trainer button. When the
instructor releases the button, he can exer-
cise direct control over all operations.
5. Perform neutral adjustment of the other
transmitter on the ground before beginning
actual flight. Adjust the trim of both transmitters so that the rudder servos are not
operated when the trainer button is depressed.
6. Since power is supplied from Tx1 even when
the student is operating, the current drain of
Tx1 will be about 10% greater than when
used independently.
7. Deflection of the meter will become small
when the trainer cord is connected, but this
is normal.

NICKEL-CADMIUM BATTERY AND CHARGING METHODS
• The FP-T3FN, FP-T4FN, FP-T5FN, and FP-T6FN transmitters are each equipped with a built-in nickel-cadmium
battery (8/450 mAH) power supply.
• Use a nickel-cadmium penlight cell (4/450mAH) as the receiver and servo power supply.
• Charge the nickel-cadmium battery for 12~15 hours before normal use. Charge the battery for 20 hours when
it has not be used for an extended period of time. Slight overcharging will cause no harm to the battery.
• A fully charged nickel-cadmium battery can normally be used about 10 times at a 10 minutes/time rate.
• The nickel-cadmium battery will supply a uniform voltage for a certain period of time, but pay careful attention
to the voltage after being used 7~8 times.
Connect the battery charger supplied with the FP-3FN, FP-4FN, FP-5FN, and FP-6FN as illustrated in Figure 5.

The 3P red female connector of the switch harness is used to charge the NR-4C (receiver and servo use NiCd
battery) without removing it from the model.
To
charge the NR-4C (receiver and servo NiCd battery) without removing it from the model, set the switch to
the OFF position and connect the 3P red male connector from the charger to the 3P red female connector of
the switch harness.
Charger (RX)
1. The cord with the power plug at both ends is the Tx charging use cord. To charge the transmitter, connect
this cord to Tx of the charger and "A" of the transmitter.
2. The cord with the power plug at one end and the 3P connector at the other end is the RX charging use cord.
When charging the NR-4C receiver use nickel-cadmium battery, connect the power plug end of this cord to
RX of the charger and the 3P connector end to the NR-4C.
3. Plug the charger plug into an AC line receptacle (AC 115V, 220V, 240V).
4. Charging is performed with the above operations. At this time, the LED of the charger will be illuminated to
indicate that charging is being performed.
5. Be absolutely sure that all the connections are correct. If the NR-4C receiver use nickel-cadmium battery is
connected to Tx, the battery may be damaged by overcharging.
6. The special charger can charge the transmitter battery and receiver battery simultaneously or independently.
PERFORMANCE TEST AND MOUNTING PRECAUTIONS
1. Verify that the receiver and servos are connected in accordance with Figure 3. Then, make the transmitter
antenna
as
short
as
possible and
30m. Operation is normal if all the controls are functioning properly. Perform this test within a maximum of
5 minutes time. Never perform this test when the transmitter antenna is not mounted to the transmitter. Otherwise the transmitter will be adversely effected.
2. Be careful that the receiver does not directly touch other mechanisms of the aircraft itself. Moreover, wrap the
receiver in sponge rubber so that it is not subjected directly to engine vibrations. (In the case of boat use, cover
the sponge wrapping with a vinyl bag and tie securely at the point at which the cord enters so that no water can
enter the receiver.)
extend
the receiver antenna and attempt operation
from a distance of
20m~
3. The use of a servo tray is extremely convenient when installing the servos. The method of installation is
illustrated in the figure. (Insert each connector fully.) Don't forget to confirm that the motion of the servo horns
and rods matches the direction of operation of the transmitter sticks. Use the reversible servo (L servo) as a
shoulder wing throttle servo or for rudder and nose gear operation.
• NOTE; The L servo cannot be used for aileron control. (The operation of the stick and rudder are opposite.)

4. After setting the push rod at each servo, operate each servo fully left and right at least once. If the rod catches
or sticks at this time, the servo has been damaged by an overcurrent. Therefore verify that the rods are
functioning perfectly.
5. Be especially careful of noise signals. For instance, noise signals will be generated by the contact of metal
against metal due to engine vibration. If these noise signals are received at the receiver, the receiver may operate
erroneously. Therefore cover one of the metal surfaces with insulating material.
6. After installation is complete, ask a nearby radio control expert or the dealer where the equipment was purchased
to instruct you on the proper handling techniques and other items which may require special attention. Also
have your installation thoroughly checked at this time.
Strict observance of safety rules and adherence to the advise of experts will make radio control more enjoyable.
