•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. The FP-8SSHP was specially developed for FAI RC aerobatics F3C use. Please read this manual before using your set. TRANSMITTER FP-T8SSHP • Newly designed rotatable open gimbal stick provide maximum operation feel. Stick position and spring tension can be adjusted.
2 •DSC circuit. Each servo can be controlled from the transmitter without turning on the transmitter by connecting the transmitter directly to the C terminal. •The receiver is a miniature PCM receiver in which the highest reliability has been pursued. It is the first R/C receiver in the world to use the newest computer technology. •Miniature PCM receiver with hi-speed singlechip microprocessor. Resistance against adjacent band and noise interference has been increased by one full order of magnitude.
•TRANSMITTER This section explains the operation of the transmitter controls when the servo reversing switches are in the normal position. When the reversing switches are in the reverse position, servo operation is the opposite of that described here. 1. AllerOn Controls the ailerons. 2. ElevatOr Controls the elevators. 3. Throttle Controls the throttle. 4. Rudder Controls the rudders. 5.
14. Aileron dual rate switch 15. Elevator dual rate switch Aileron dual rate ON-OFF switch. When set to the pull position dual rate is turned on, and when set to the push position, dual rate is turned off. At dual ON, the deflection can be set as shown in Fig. 7 with the (1) aileron dual rate trimmer located on the trimmer panel at the back of the transmitter. At dual OFF, the operating linearity can be switched as shown in Fig. 8 with the (2) LINEAR-VTR switch also located on the trimmer panel.
(19) Idle up 1 switch ( 1 switch) Right ON, Left OFF. (20) Idle up 1 ratcheted knob (1 knob) Throttle servo •When the 1 switch [19] is set to ON, the throttle servo "stop position" (idle up amount) can be adjusted with this knob. • If fail safe switch [13] on the trimmer panel at the back of the transmitter is set to the INH position, the idle up 1 function is inoperative. Light goes out to indicate that.
22 Hovering throttle ratcheted knob 24 Monitor lamps •Trims the throttle servo independently from the pitch control servo (without regard to mixing). Since the throttle servo can be trimmed without interfering with other mixing, this knob is very convenient when trimming the throttle while hovering. • When the throttle lever [3] is at about the center, the throttle servo throw can be adjusted about 25% of the total travel with this knob.
25 Rotative open gimbal stick • Rotative open gimbal stick allows setting of the operating direction of the stick within a range of ±34 degrees by losening screws 1 to 4 in the figure 1/2 turn and turning the stick grille. • Set the stick in the direction in which operation is easiest. • After setting, retighten the screws. • The new gimbal is open. This one has been used only for the most expensive radio controls. It also has the built-in tension adjustment mechanism on open gimbal for the first time.

This switch switches the travel linearity of the aileron servo when the aileron dual rate switch [14] is in the OFF position. Fig. 31 Remove the back cover by pulling stoppers in the direction of arrows. Fig.
B Pitch A Inverted flight low-side trimmer 3 High side pitch trimmer. Adjusts the high side pitch from about 60% of the full throw of the pitch control servo as shown in Fig. 35. B Inverted flight high-side trimmer • The inverted flight function can be turned on and off with the [c] inverted flight FS switch on the trimmer panel at the back of the set.
4. Normal pitch trimmer Adjusted to match normal flight. 5. This trimmer sets the low pitch (minus pitch) when the throttle hold switch [23] is ON. It is adjusted to the auto-rotation pitch. 6. This trimmer adjusts the low pitch (minus pitch) when the idle up [2] switch [21] is ON. It is used during rolls, etc. 7. Hold delay trimmer. This trimmer adjusts the delay time the pitch servo operates when the throttle hold switch [23] is set to ON. An operating time of 0 to about 2 seconds can be set. Fig.
E. Elevator Rudder servo Settable within this range by trimmer [16] . 23. Elevator dual rate trimmer This trimmer adjusts the elevator servo throw when the elevator dual rate switch [15] is set to ON. It has the same functions as the aileron dual rate trimmer [1] described on page 13. 24. LINEAR <-> VTR Fig. 41 16 Fig. 42 17. This trimmer sets the rudder servo throw and direction when the rudder button [33] is set to ON (pressed). The servo throw can be adjusted up to the total travel. 18.
G. 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. Linkage rattle is also minimized. Fig. 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.
H. Servo reversing switches These switches reverse the direction of the servos. They are very convenient when connecting the linkage.
