HANDLING THE TRANSMITTER

•The name of each part of the transmitter is given in the figure.

Familiarize yourself with their operation.

•Remove the battery cover on the rear of the transmitter as illustrated in the figure, and insert 8 round penlight batteries, paying careful attention to their polarity.

•Extend the antenna fully, and set the power switch to the

ON position. The pointer of the level meter should deflect to the green zone. If it fails to deflect, or deflects slowly, the polarity of the batteries is incorrect, or the batteries are faulty.

•Since the range of the radio waves will become short when the pointer of the level meter deflects to the red zone, replace the batteries when the pointer only deflects to the boundary between the green and red zones.

•The trim lever is used to fine adjust each channel. Use it for neutral adjustment and to correct the flying posture after the mechanism has been installed. After test flight, operate with the trim lever in the neutral position, as far as possible, by correcting with the rod adjuster, etc.

•Since the elevator stick employs a self-neutral system, install the sliding plate as shown in the figure when changing it to a ratchet system. Then remove the strong spring attached to the hook and replace it with the spring supplied as an accessory.

•When the transmitter is used with a tank, the direction of the stick can be changed 90 degrees by removing the four rudder stick mounting screws.

•To change the crystals, loosen the rear cover mounting screws, remove the rear cover, and then replace the crystal. The crystal is located at the left side of the printed wiring board.

The transmitter crystal is marked (T) and the receiver crystal is marked (R). CAUTION: Frequency change has to be done under the supervision of FCC licensed personnel.

•Set the transmitter power switch to ON, then set the receiver power switch to ON. The servos stop near the neutral position.

Operate the transmitter sticks and check if each servo faithfully follows operation of the sticks.

•Connect the pushrod to each servo horn, then check if the direction of travel of each servo matches the transmitter operation.

•Operate each servo over its full travel and check if the pushrod binds or is too loose. Applying unreasonable force to the servo horn will adversely affect the servo and quickly drain the battery.

Be especially careful when using 8.4V.

• A l w a y s make the full stroke (including trim) of the servo horns somewhat larger than the full travel. Adjust the servo horns so that they move smoothly even when the trim lever and stick are operated simultaneously in the same direction.

• Be alert for noise.

Always solder a noise killing capacitor to the running motor. If metal parts touch each other due to vibration, noise will be generated and cause the receiver servos to operate erroneously. We recommend the use of noiseless parts.

• Even though the receiver antenna wire is long, do not cut or bundle it. The range of the radiowaves will be shortened.

• A spare horn is provided. Use it as required.

•Wrap the receiver in sponge rubber and wrap rubber bands around the sponge rubber. Mount the receiver so it is not exposed to vibration, does not touch the frame, and does not move.

•When the receiver is installed on a board or used where it may be splashed with mud and water, place it in a plastic bag, etc. and wrap a rubber band around the open end of the bag to waterproof and dustproof the receiver. After use, remove the receiver from the bag to prevent condensation.

• Use the rubber bands wrapped around the receiver to hold the servo and switch leads.

•After mounting is complete, recheck each part, then check the transmitting range by making the transmitter antenna as short as possible and extending the receiver antenna fully and operating the set from a distance of 20m to 30m. The movement of each servo should follow the movement of the transmitter sticks.

•The crystal can be changed from the outside of the receiver case.

Always use a Futaba transmitter and receiver crystal pair as the replacement crystals.

• Install the servos firmly. Install the servo to the servo tray as shown in the figure. In other cases, install the servo as described in the model manufacturer's manual.

REPAIR SERVICE

• When requesting repair of trouble that has occurred suddenly of from long use, describe the trouble symptoms in as much detail as possible.

This will facilitate detection of the trouble point and shorten the repair period greatly.

• Defects caused by faulty materials or workmanship will be corrected free of charge.

• This limited warranty is null and void if the set has been tampered with or disassembled.

Refer to warranty statement for details.

•The frequency of Futaba digital proportional sets can be changed among bands (1)

~ (6) on the 27MHz band only.

• However, a 27MHz band set cannot be changed to 72MHz band, and vice versa.

•Therefore, always attach the correct frequency flag to the end of the transmitter antenna. Each frequency band has its own designated color, as stated in the left. The frequency flag is intended for identification purposes.

• A l s o change the frequency flag when fre-

quency is changed.

• Futaba paired crystals are precisely matched.

A l w a y s use a Futaba crystal set (transmitter, receiver) when changing the frequency.

• It is illegal to change crystals of transmitter on the 72-75MHz bands in the U.S.A.

The following splined horns are optional.

• SPLINED HORNS

This horn permits shifting of the servo neutral position at the servo horn. Setting and shifting the neutral position a) Angle divisions

1) The splined horn has 25 segments. The amount of change per segment is; 360/25=14.4°

2) The minimum adjustable angle is determined by the number of arms or number of the holes. For four arms, the minimum adjustable angle is: b) Effect

To shift the holes center line to the right (clockwise) relative to baseline

A, shift arm 2 to the position of arm

1 and set it to the position closet to baseline A.

(Example] For a four arm horn. the angular shift per segment is 14.4°.

The shift to the right is 90° - (14.4 x

6» = 3.6°

To shift by the same angle in the opposite direction, use the opposite arm number.

For a six arm horn, turn the arm counterclockwise and set arm 2 to the position of arm 1. The adjustable angle is 60° - (14.4 x 4) = 2.4°.

Arm 3 shift 4.8° to the right, arm 6 shifts 2.4° to the left, and arm 4 shifts 7.2° to the right and left.
