•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 micro-
processor 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  posi-

tion and spring tension can be adjusted.

•RF module system. The frequency band can

be changed with one touch.

•DSC (Direct Servo Controller). The servos can

be operated without turning on the trans-
mitter.

Wire  operation  is also possible by using the
special cord supplied with the set. (FSC-1)

•Servo  reversing  switch on all channels. The

direction of operation of each servo can be
reversed with the flip of  a switch.

•Dual rates or non linear VTR (variable trace

ratio) on the aileron,  elevator, and rudder

channels.  Aileron  and  elevator  dual rate can
be switched simultaneously, or independently.

•Easy-to-adjust  two-knob  revolution  mixing.

Pitch  control -> rudder and throttle -> pitch
control mixing.

•Revolution  mixing compensation. The revolu-

tion  mixing  (pitch  control -> rudder mixing)
up side can be set in the  direction at which
the  mixing  amount to the rudder becomes
smaller.  This increases  high-speed straightfor-

ward flight and also  minimizes the  power loss.

•Acceleration  mixing.
•Throttle hold function for auto-rotation.
•Throttle hold delay. The pitch servo operating

time at throttle hold can be freely set with a
built-in  delay  circuit.

•Four (4) pitch-curve trimmers for best pitch

for  hovering  and  maneuvering.

•New  single-chip  microprocessor  allows  one-

touch  fail safe setting  and  introduction of an
automatic  transmission  system which elimi-
nates  the need for fail safe setting at the be-
ginning of each flight and improves safety.

•Hovering throttle permits independent adjust-

ment of the hovering  point  throttle  position.

•Hovering pitch lever  permits independent

adjustment of the hovering  point pitch with-
out regard to the throttle.

•Two idle up functions used for static and

dynamic aerobatics.

•Hovering  memory reproduces the best mixing

point at any throttle  position & even during
performance of flight.

•Throttle ATL (Adjustable Throttle Limiter)

allows  simple and reliable throttle linkage
hook-up.

•Rudder  button with timer is convenient in

540*  stall  turns.

•Tachometer/timer  with  built-in  tachometer,

up timer, down timer, integrating timer, and
battery  alarm.

•New ATV (Adjustable Travel Volume) on all

channels  allows  independent pushbutton ad-
justment of servo  left,  right,  up, and down
throw.

•Second ATV. Besides new pushbutton ATV

on aileron and elevator, conventional trimmer
ATV is also installed.

•Monitor lamp glows  when two idle up systems

or throttle  hold is set and flashes when they
are working.

•Fail safe switch (safety switch).  Internal

switches that turn  the throttle hold, idle up,
and other functions on and off.  If the internal
switch  is set to off beforehand, when that
function  is  not used, it will not operate even
if the switch on the transmitter is set to on.

•Built-in power error back-up circuit. When the

internal  Nicd  battery approaches the  fully

discharged  state, an  LED  blinks to indicate
that the memory circuit (memory, ATV, FS,
etc.) is not working.

•Two servo test functions. A slow sweep to

check neutral characteristic,  trackability and
to cycle  servo to test servo operation.

•Highest quality aluminum case with sophisti-

cated design. The transmitter fits easily in
your  hand.

•Optional CCPM (Cyclic Corrective Pitch  Mix-

ing).

• Trainer  system  offers

an easy training of

flight for beginners.
