• FEATURES This radio control set has been developed for FAI RC acrobatic F3A use. Please read this manual thoroughly before using your set. Transmitter FP-T8JN Receiver FP-R8J •The transmitter employs a module system. The frequency band and modulation method can be changed with one touch. •The servos can be operated without transmitting radio signals. Wire operation is possible by using the special cord furnished with the set. •A reversing device is self-contained.

• TRANSMITTER CONTROLS Fig.
Purpose of switches and trimmers in Fig. 2 The numbers in circles represent the channel number. The channel numbers on the front of the transmitter correspond to the receiver connector output numbers. Aileron reverse switch NORM-REV This switch reverses the direction of rotation of the aileron servo. Elevator reverse switch NORM-REV This switch reverses the direction of operation of the elevator servo. Throttle reverse switch NORM-REV This switch reverses the direction of operation of the throttle servo.
Throttle button trimmer THROT The throttle servo is operated at the position set by this trimmer by pushing the throttle button. The total travel can be set at throttle stick neutral position. Roll A button trimmer 1 ROLL (A) Roll B button trimmer 1 ROLL (B) This trimmer sets the aileron travel when the roll button is pushed. The travel is variable over the entire travel range at aileron stick neutral.
• USING THE TRANSMITTER Before using the transmitter, charge the NiCd battery. •Connect the DIN connector of the FBC-2L charger to the charging jack of the transmitter and the 3P connector to the receiver servo NiCd battery (NR-4H), and plug the charger into an AC110V outlet as shown in Fig. 3. The Tx, Rx charging indicator LED illuminate to indicate that the battery is being charged. •The charging time is normally 15 hours. But if the battery has not be used for some time, charge it for about 20 hours.
when desiring to make the spin and other steering angles large, set it to ON and adjust the horn, adjusters, and trimmers for level flight. When the dual travel switch is set to OFF, kick up is set, and the steering angle becomes large. •Aileron, elevator, and rudder right and left (UP. DOWN) angle adjustment [ATV (Adjustable Travel Volume)] The aileron, elevator, and rudder steering angles can be made small within the range of the hatched lines in Fig. 6.
(NOTE) Always release CH7 switch (spoiler) of Fig. 1 before releasing MIX switch when releasing mixing. If these switches are released in the reverse order, only the flaps will be released and the spoiler will remain open, placing the aircraft into an extremely dangerous state. •Roll button A (Fig. 1 ROLL[A]) The ailerons can be stopped at an arbitrary position while this button is being pushed. This is used at slow roll, etc. Adjust the steering angle with the ROLL (A) trimmer of Fig. 2.
• USING THE RECEIVER SERVOS Aileron servo
•The receiver channel order is shown in Fig. 8. Stick the channel tabs furnished with the set to the servo lead wires for identification. •Use an extension cord matched to the fuselage. •Wrap the receiver in sponge and fasten to the fuselage with rubber bands. •Install the receiver so that the antenna wire is as straight as possible. •Mount the servo as shown in Fig. 9. •Mount the servos so that the flexible wire, hinges, and other steering mechanisms operated smoothly.

• MODULES The frequency, frequency band, and modulation (AM, FM) of the J Module Series can be changed. The transmitting and receiving modules are available as a pair. EXAMPLE 1. : Switching from 27.195MHz to 27.045MHz Replace both the transmitting and receiving modules with the 27.045 MHz RF module. EXAMPLE 2. : Switching from 27.145MHz to 72.080MHz Replace both the transmitting and receiving modules with the 72.080 MHz RF module. EXAMPLE 3. : Switching from 72.240MHz to 53.
