[. . . ] Reliability is increased and the crystal can be changed from the outside. Power supply Current drain Dimensions Weight RECEIVER FP-R4H, (FP-R104H)_________________ Miniature 4 channel AM receiver Receiving frequency :27MHz band 72/75MHz band Intermediate frequency :455kHz Power requirement :4. 8V to 6. 0V Current drain :10mA Dimensions :1. 26 x 2. 05 x 0. 77 in. (32 x 52 x 19. 4 mm) Weight :1. 06 oz (30g) Receiving range : 220 yards(200m) on the ground when used with the FP-T2PKA(At the best radio wave condition of environment) RECEIVER FP-R104H_______________________ · High performance AM 4 channel receiver in which miniature size and light weight have been achieved by using the PC board space to the maximum. · Short (50cm) antenna designed for miniature models is easy to mount. (27MHz only) · Narrow band design using a narrow band ceramic filter resists adjacent channel interference. [. . . ] 10. (5) Throttle trim knob (6) Throttle ATV high side trimmer ATV. . . (7) Throttle ATV low side trimmer Throttle ATV is a device which permits independent adjustment of the throttle servo left and right sides (from neutral) as shown in Fig. (FP-T2PKA) Remove from the holder and screw in vertically. ATV is the abbreviation for Adjustable Throttle Volume and is an extremely convenient device by which steering servo travel volume can be adjusted freely with two trimmers preloaded. The relationship between two trimmers does not change even when servo is reversed. 10 (16) Battery cover When loading (or changing) the eight penlight batteries, remove this cover as shown in Fig. (17) Transmitter crystal When changing the frequency, replace this crystal. The transmitter crystal is marked TX and the receiver crystal is marked RX. However, you are not allowed to change frequency by merely replacing crystal on both 72 and 75MHz. Throttle Servo The BEC mark is displayed on the front of the receiver of BEC (Battery Eliminator Circuitry) system sets with a receiver with shared power supply regulator. RECEIVER FP-R102GR AND SERVO FP-S148 Fig. 11 (3) When motor car uses an ordinary common power supply chassis (2) When motor car uses a special BEC system chassis (common power supply specifications) Red common 2P connector Red common 2P connector (Female pins) Buy the red common 2P connector from the kit manufacturer and connect to the controller. Plus Connect to the red common 2P connector of the controller. The Futaba BEC (Battery Eliminator Circuitry) system can also use a common power supply with the conventional four penlight batteries system (separate power supply). · A common power supply regulator and diode may also be supplied with the speed controller, depending on the vehicle kit. Since they cause a voltage drop, always remove them. · Set the transmitter power switch to ON, then set the receiver power switch to ON. 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. · Always 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. If metal pans touch each other due to vibration, noise will be generated and cause the receiver servos to operate erroneously. Even though the receiver antenna wire is long, do not cut or bundle it. The range of the radiowaves will be shortened. Receiver antenna wire -- Wood screw ten cB -Rubber bushing -Gromet Fig. In other cases, install the servo as described in the model manufacturer's manual. Fig. 13 · · · · A spare horn is provided. [. . . ] Please note there are specific frequencies allocated for aircraft only and surface only use. · The frequency can be changed within the same BAND by using a precisely matched pair of Futaba crystals. However, Futaba recommends that you return your system to our factory service department for frequency changing, as tuning may be necessary for proper operation. The frequency flag is to be attached to the top of antenna and the channel designation to the base. [. . . ]
