User manual FUTABA FP-8SSHP

[. . . ] Futaba DIGITAL PROPORTIONAL RADIO CONTROL PCM SINGLE STICK PULSE CODE MODULATION SYSTEM D60421 Thank you for purchasing a Futaba digital proportional radio control set. Please read this manual carefully before using your set. When reading this manual, refer to the foldout at the end of this manual. CONTENTS FEATURES . 33 ·FEATURES The FP-8SSHP is a digital proportional R/C set with PCM (Pulse Code Modulation) for helicopters. The system is extremely noise and dead-point resistant digital proportional R/C sets with a microprocessor in the transmitter and receiver. [. . . ] Rudder time trimmer This trimmer sets the time the rudder servo stops at a fixed deflection when the rudder button [33] is pressed. Rudder button fail safe switch When this switch is set to the RUD. REV position, the rudder button operates. When it is set to the INH side, the rudder button becomes inoperative. Fig. It is a device which allows independent adjustment of the servo left and right (up and down) throw without affecting the neutral position. Because of the engine torque, precision of the model, and for other reasons, the radius of left and right turns is always different even if the left and right steering throws are perfectly matched. The A T V is most convenient when left turns are good, but right turns are to sharp. In this case, left and right turns of the same radius can be easily made by reducing the servo right throw slightly. The aileron and elevator 2nd ATV is the conventional trimmer type ATV. 20. Rudder dual rate trimmer This trimmer adjusts the rudder servo throw when the rudder dual rate switch [ 6] is set to ON. It has the 1 same functions as the aileron dual rate trimmer [1] described on page 13. This switch has the same functions as the aileron LINEAR <-> VTR switch described on page 13. Revolution [ 7] and [ 8] and acceleration mixing 1 1 trimmer [15] direction switching and function OFF switch ·When the main rotor turns clockwise, set this switch to the R position. If the main rotor rotates counterclockwise, set this switch to the L position. (The linkage may also be reversed. ) ·When the switch is set to the center position, the revolution [17] and [18] and acceleration [15] functions are turned off. Aileron [26] right Aileron [27] left [28 Elevator up [291 Elevator down Fig. Cyclic Corrective Pitch Mixing (optional) CCP mixing is performed after the helicopter corrective pitch and cyclic pitch control systems are electrically mixed. Since direct linkage from the servo to the swash plate is possible by using CCP mixing, the model can be made lighter by eliminating the intermediate mechanism. 46 30 CCPM switch 1 and 2 turn MIX ON-OFF and switch the pitch direction when the CH2 (elevator) servo is operated as the pitch servo. CH1: Reverse CH6:Normal CH2: Reverse CCPM: (2) CH1 solid line indicates reverse CH1 dotted line indicates normal ·When mounting the servos in the fuselage, mount the CH1 servo (aileron servo) at the right side facing the front and the CH6 servo (pitch servo) at the left side facing the front. ·Set the CH2 (elevator) up and down directions with the reversing switch. Next, set CH2 elevator to pitch operation and set the switching and pitch direction with CCPM SW1 and 2. ·Check if the high, low, aileron left and right, and elevator up and down directions are correct by pitch operation. ·Set aileron CH1, elevator CH2, pitch CH6, ATV, and 2nd ATV to maximum. When the CCPM switch is set to ON, the CH1, CH2, and CH6 servos throw is automatically set to 50% of the total travel.
