[. . . ] High output torque 55. 6 oz-in (4kg-cm), high-speed 0. 24sec/60° · New indirect drive potentiometer improves vibration and shock resistance and neutral accuracy. · Futaba low-power custom 1C provides extremely high torque, narrow dead band, and superior tracking. · Fiberglass reinforced PBT (polybutylene terephthalate) injection molded servo case is mechanically strong and invulnerable to glow fuel. · Strong polyacetal resin ultra-precision servo gear features smooth operation, positive neutral, and very little backlash. [. . . ] by turning them Unlock lever heads and in the arrow direction, and adjust the head to the most comfortable length, then lock it by turning it in the direction opposite the arrows. Fig. 4 Transmitter crystal Aileron AST trimmer Elevator AST trimmer AST is the abbreviation of Adjustable Servo Throw. Idle up trimmer This trimmer is effective when the idle up switch is ON. It adjusts and sets the throttle hold maximum slow position, and can be set as shown in the figure. Neutral · The tension of the spring can be adjusted by removing the transmitter back cover and turning the screw for each stick. Set the springs for the best stick feel. Throw can be adjusted and set over this range. 5 HIGH Elevator MAXIMUM SLOW Throttle stick deflection The idle up amount of the throttle servo can be adjusted and set within this range with the throttle up trimmer. When adjusting the aileron, and elevator the inside module is removed. 6 Servo reversing switches Using the servo reversing switches · The left side of each switch is the normal position. · The servo reversing switches reverse the direction of operation of the servos. Fig. ·CHARGING OF TRANSMITTER AND RECEIVER NI-CAD BATTERIES: Battery Charger Type FBC-8B(4) Recharge the receiver and transmitter NiCad batteries as shown in Fig. 2) Then connect to RX NiCad after connecting, L, E, D, chanqes color from red to greenish red (orange) which indicates that both TX and RX NiCads are being charged. 3) In case of separate charging L, E, D, color will be: RX NiCad - Green. However, if the throttle (engine control) stick is at SLOW, the neutral position is from the left and if the throttle (engine control) stick is at HIGH, the neutral position is from the right. Throttle stick 12 If the helicopter turns to the left during hovering, turn the revolution mixing up side knob clockwise. 13 Rate gyro output adjustment (when FP-G153 used) A position about 40% to 80% of the rate gyro control box scale should be sufficient. (Differs somewhat with the model. ) If the tail of the helicopter whips back and forth, the gyro output should be increased. · Idle up adjustment When the idle up switch is OFF, the throttle servo operates normally as shown in Fig. When the switch is ON, when the idle up trimmer is suitably set, the throttle servo changes to the maximum slow position as shown in Fig. When idle up is used, hovering is stable and the rotor speed can be held even when the pitch is reduced during rolls and prettier maneuvers are possible. 1 Set the transmitter throttle (engine control) stick to maximum slow and set the idle up switch to ON and set the idle up trimmer to about 20 to 25%. 2 Next, set the idle up switch to OFF, start the engine, hover, and decide the speed at hovering. Set the idle up switch to ON, hover, and adjust the idle up trimmer so that the speed is about the same as, or somewhat slower than, that when the idle up switch is OFF. When starting the engine and after use, always set the idle up switch to OFF. SLOW SLOW HIGH HIGH neutral position SLOW HIGH Right Left Up side mixing amount A. 14 When the main rotor rotates, the helicopter attempts to turn in the opposite direction. [. . . ] If the helicopter turns to the left, turn the knob counterclockwise. Fig. 17 · Throttle hold adjustment When the throttle hold switch is pulled on, the throttle servo stops at the position set with the throttle trimmer. Setting to the high side is possible as the number of divisions increases. When the switch is OFF, the throttle servo is controlled by the transmitter throttle (engine control) stick. [. . . ]
