User manual FUTABA 2PKA

[. . . ] FEATURES OF MAGNUM JUNIOR The Magnum series are pistol grip type of AM 2 channel digital proportional radio control sets and are the best in their class. SET CONTENTS AND RATINGS FP-T2PK MAGNUM JUNIOR Transmitter FP-T2PKA TRANSMITTER FP-T2PKA, (FP-T2PK)_____________ · Newly designed cockpit type control panel · Human-engineered size and design are easy to use. ·Steering rate adjuster The steering servo travel volume (right 81 left evenly from neutral) can be adjusted simultaneously, while running. ·Throttle ATV The throttle servo travel volume can be adjusted and set with two trimmers, independently. The turning angle of the steering wheel can be increased and decreased. [. . . ] (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. Use the AM crystal set (transmit and receive 1 pair) sold by Futaba. 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. 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. · 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. Always solder a noise killing capacitor to the running motor. If metal pans 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.
