NOTE:

Please read and follow instructions for installation and usage in their entirety and follow carefully. Failure to follow instructions could result in serious property damage and/or personal injury. This system is intended for use by exp erie nced R/C hobbyists. Beginners should seek expert advice and Assistance before operating this system.

•FEATURES

The FP-8SSAP was specially developed to use PCM (pulse code modulation) for FAI RC aerobatics F3A aircraft. It is an extremely noise and dead-point resistant digital proportional RC set with a microprocessor in the transmitter and the receiver. Please read this manual before using your set.

TRANSMITTER FP-T8SSAP

•Pitch

• RF module system. The frequency band can be changed with one touch.

• DSC (Direct Servo Controller) allows operation of the servos without turning on the transmitter. Wire operation is possible by using the special cord supplied (FSC.1).

•Servo reversing switch for all channels allows reversing

• Dual rate or non-linear VTR (variable trace ratio) aileron, elevator, and rudder. Two-stage

dual rate on aileron.

• Elevator -> flap mixing is especially advantageous in circle aerobatics.

• Flap, spoiler -> elevator mixing allows control of

the aircraft attitude while using the air brake

(flap, spoiler).

• Throttle -> (flap, spoiler) -> elevator mixing

allows enhancement of the air braking effect by throttle lever operation when div in g and landing.

• Programmable mixing function permits mixing

with the desired channel.

• Four-function snap roll switch (Timer is op-

tional).

• Idle-up lever, the engine idling speed can be independently adjusted during throttle -> pitch

control mixing.

• New single-chip microprocessor allows one-touch

fail safe setting and introduction of an automatic transmission system which eliminates the need for fail safe setting at the beginning of each flight and improves safety.

GLOSSARY OF TERMS

NOTE: Please take the time to familiarize yourself with the terms and abbreviations below. They will be used throughout the instructions and are important in understanding the operation and potential of your system.

PCM (Pulse Code Modulation) SERVO REVERSING

Pulse Code Modulation utilizes a precise digital code to convey information from the transmitter encoder to the receiver. This state of the art method makes many of the sophisticated functions of the FP-8SSAP possible, as well as providing far superior immunity to noise and interference than is possible with conventional encoding methods.

ATV (Adjustable Travel Volume)

This feature allows independent adjustment of

servo travel in each direction. ATV is sometimes

referred to as "endpoint adjustment". Two dif-

ferent types of ATV are standard with this system,

(1) Pushbutton or Programmed (Memory) ATV and (2) 2nd ATV (Conventional).

MEMORY ATV

This type is available on all eight channels. These adjustments are stored in the transmitter memory circuit and are retained when the power switch is turned OFF. They are lost however, if the trans-

mitter Nicd batteries reach full discharge.

2ND

ATV

Available on Aileron (CH 1) and Elevator (CH 2). This is the conventional type ATV which is set by using trimmer pots on the transmitter back panel. These settings are NOT affected if the transmitter batteries are discharged.

DUAL RATE

Rate switches allow the pilot to select different

servo travel limits (for varying control sensitivity)

in flight. Servo travel is affected equally in both

directions from center.

SAFETY (ACT/INHIB)

These switches, located on the transmitter trimmer panel allow mixing and certain other functions to be deactivated when not desired. When the Safety Switches are set to the INHIB position, the function will remain OFF even if the transmitter control switch is set to ON.

VTR (VARIABLE TRACE RATIO)

This is a special type of non-linear control response. When VT R is used, servo travel is normal and linear up to about 80 percent of the transmit-

ter control stick movement where the servo travel

is abruptly increased to a higher rate (both rates

adjustable). This allows a normal feel f or most fly-

ing with extra movement available for emergencies

and certain acrobatic maneuvers. Another way to think of this function is as "automatic Dual Rate".

SWITCHES

This function allows the modeler to reverse the

direction of servo movement (in relation to control stick movement) for various installation requirements. This can be done by conveniently

flipping a switch on the trimmer panel. Servo travel and neutral position are not affected.

MIXING

general, mixing functions allow two or more different channels to be operated by moving a single transmitter control. Many useful and versatile functions are made possible in this manner. Three types of mixing functions are provided.

(1) Unidirectional mixing — This function allows one or more channels to be "slaved" to a "master" channel. Movement of the master channel control causes movement of both master and sl aved servos simultaneously. Operation of the slave channel control however, does not cause movement of the master channel servo. An example is Aileron/Rudder mixing (see page 3 3) wh ere the Rudder is slaved to Ailerons for coordinated turns. (2) Mutual (Bi-Directional) Mixing - With this type of mixing, two channels are mixed so that operation of the control for either channel causes movement of both servos. This is useful in providing sophisticated functions such as V-tail operation,

flaprons, and

(3) Switch-Activated Mixing — Two or more-

channels can be programmed so that the servos

involved move to a preset position when a trans-

mitter control switch is pulled or button pushed. Snap roll switches, roll buttons, and pre-set switches are examples of this type of mixing.

PROGRAMMED MIXING FAIL SAFE

Unidirectional mixing of any two channels desired is possible using the pin board and jumper connectors on the transmitter back panel. Either channel may be designated as "master" or "slave".

DSC

(Direct

Servo

Control) Operation of the entire system with the transmitter switch in OFF position is possible using the

DSC cord. This is useful for checking and adjusting control movements on the ground while someone else is flying on your frequency.

The Fail Safe function moves servos to a pre-set position if the transmitter signal is lost or interrupted by strong interferrence. The servos will be held in the pre-set position until a proper signal is

again received at which time Fail Safe is released.

Lamp A Power Monitor

• When the power switch briefly and then goes out momentarily as the Fail Safe data is automatically matically transmitted to the receiver. Fail Safe data is transmitted every 60 seconds at which time the lamp al so goes out momentarily. If the transmitter Nicd battery nears full discharge, this lamp starts blinking, indicating that the power error backup function is activated. When this occurs, transmitter memory function settings are lost and must be reset.

LampB3 -> 6. 7 -> 2 I 3 -> 8 Mix

This lamp comes on when Safety Switch 7 and/or [33] is set to ACT position, indicating that throttle —-> flap, spoiler —-> elevator mixing and/or throttle -> pitch control mixing functions are activated. This lamp will blink when transmitter control switch II is set to ON (placing these functions in operation).

Lamp C 6, 7 -> 2 Mix

• This lamp comes on when Safety Switch [32] is set to ON (flap, spoiler -> elevator mix) or CH7 OFF (flap -> elevator mix) position. This lamp blinks when transmitter control switch 10 is set to ON.

Fig.1

When the power switch 23 is set to ON, lamp (A) will go out momentarily. This indicates automatic data transmission on and is not a failure.

23 Power switch

• The transmitter power ON-OFF switch is provided with a locking feature to prevent accidental movement. To operate the switch, pull the knob gently outwards and set to the desired position (UP=ON. DOWN=OFF).

25 Level meter

• This meter indicates the transmitter battery voltage and output power.

•W hen the antenna 26 is extended fully and the power switch 23 is set to ON, the pointer should move to the white zone.

The airborne batteries can also be charged through the DSC/CHG harness by connecting the CHG adaptor to the charger as shown in Fig. 9. In this manner, the airborne batteries can be charged without removing them fr om the model.

•Normally recharge the battery for about 15 hours. If it has not been used for some time, discharge and recharge it two or three times and then charge it a full 15 hours.

• The amount of time remaining before the batteries must be recharged can be estimated using the Integrating Timer function of the Tachometer/Timer
