•GLOSSARY O F 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)
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-8SGAP 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 dif­ferent types of ATV ar e 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 trans­mitter 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
using trimmer pots on the transmitter back panel.
These
settings are
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 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 OF F even if the transmitter con­trol switch is set to ON.
VTR (VARIABLE TRACE RATIO)
This is a special type of non-linear control re-
sponse. When VTR 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 fee l for most f l y-
ing with extra movement available for emergencies and certain aerobatic maneuvers. Another way to think of this function is as "automatic Dual Rate".
(ACT/INHIB)
NOT affected if the transmitter
SWITCHES
by
SERVO 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.
BFS This function provides a warning to the flyer when airborne battery voltage reaches a critically low
level
or slow position. ATL (Adjustable Throttle Limit)
This feature makes adjusting the throttle linkage much the LOW or IDLE position and not the HIGH throttle servo position. Therefore, the linkage can be set for proper opening at high throttle and the trim out changing the maximum opening.
MIXING
In 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 slaved 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 33) where 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 provid-
ing sophisticated functions such as V-tail opera-
tion,
(3) Switch-Activated Mixing — Two or more
channels can be programmed so that the servos involved move to a preset position when a trans­mitter control switch is pulled or button pushed. Snap roll switches, roll buttons, and pre-set flap switches are examples of this type of mixing.

IMPORTANT: In all instructions on control functions. Items designated by a number inside a circle (For example 10 ) are transmitter controls normally accessable and operated in flight. Items designated by a number within a box (Fo r example 10 ) are adjustment functions not operated
while in flight.
•Lamp A Power Monitor
• When the power switch 23 is set to ON, this lamp flashes on 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 ou t 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 los t and must be reset.
Lamp B3 -> 6, 7 -> 2 / 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 D Snap Roll
•When Safety Switch 29 is set to ACT (snap roll function acti­vated), this lamp blinks. When the Snap Roll switch 13 is pulled, this lamp continues blinking.
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).
Hook Metal hook for the accessory neck strap.
Level meter
•This meter indicates the transmitter battery voltage and output power.
•When the antenna 26 is extended fully and the power switch 23 is set to ON, the pointer should move to the white zone.
• If the transmitter RF Module 32 is not in­stalled, the meter pointer will not move.
• If the meter pointer moves to the red zone, indicating that the Nicd battery voltage is low,
the signal range will become shorter. If the Tachometer/timer 21 power switch is ON, the battery alarm function will operate after about one more flight. When the meter pointer stops at the boundary between the white and red
zones, recharge the battery.

Before using your system, recharge the Nicd batteries as follows:
•Connect the DIN connector of the FBC8B (2) battery charger to the transmitter charging socket 29 . Also connect the 3P connector to the airborne NR-4J Nicd battery and plug the battery charger into a 120VAC outlet as shown in Fig. 12 . The airborne batteries can also be charged through the DSC/CHG harness by connecting the CHG adaptor to the charger as shown in Fig.12. In this manner, t he airborne batteries can be charged
without removing them from 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 be fore the batteries must be recharged can be estimated using the Integrating Timer function of the Tachometer/Timer 21 . It is recommended that this function be used to monitor remaining flying time.
(See Page 11 for detailed instructions.)

•BASIC LINKAGES AND INSTALLATION
The FP-8SGAP has a servo reversing switch and ATV (Adjustable Travel Volume) for each channel. Mount the servos without regard to their direction. Select and link servo horns somewhat larger than those specified by the model manufacturer.
• Install the servos securely. Tighten the mounting screws until the rubber grommets are slightly compressed. Note: If the screws are too tight, the vibration dampening effect of the grommets will be lost.
• Use extension cords as needed.
• It is suggested that a separate servo be used on each aileron as this will allow use of the versatile mixing and differential functions built into the transmitter. Retractable landing gear can be operated with age as desired.
• Connect the pushrod to each servo horn, then check to see if the d irection of travel in relation to stick movement is correct. If the direction of travel is reversed, use th e servo reversing switches to correct.
• When installing the switch harness, cut a retangu­lar hole slightly larger that the full stroke of the ON/OFF switch and install the switch so that it operates smoothly. It is best to i nstall the switch inside the fuselage and attach a piece of wire to
the switch so that it can be operated from out­side the aircraft. Locate the switch where it will
not be exposed to engine oil, dust, etc.
•Wrap the receiver in soft foam rubber. Water­and dustproof the receiver by placing it in a

plastic bag and tyi ng the mouth of the bag with a rubber band. Do the same with the airborne battery pack. Caution: The foam rubber should be loosely wrapped and not compressed. This
will provide maximum protection from vibra-
tion.
• Use the rubber bands wrapped around the re­ceiver to hold the servo andswitch leads.
• Even though the receiver antenna may appear to be too long, do not shorten it or fold it back.
• Be al er t fo r possible electrical noise.
This system has noise rejection circuits, however
noiseless parts are recommended.
•Operate
for slop or binding in the linkage. Unreasonable force applied to the servo horns can damage the servo or horns and will greatly shorten battery
life. Adjust linkages and servo horns so that the
servos move smoothly even when the tri m lever and stick are operated simultaneously in the same direction.
• After installation is complete, recheck each part,
then perform a range check by collapsing the transmitter antenna and extending the receiver
antenna to its full length. Operate the transmit­ter at a distance of 60 to 90 feet from the receiv­er. The servos should operate normally at this distance.

•USING
GENERAL - ATV (Adjustable Travel Volume)
allows independent adjustment of servo maximum throw in each direction (without affecting the neutral position). This is also sometimes referred to as "separate endpoint adjustment". ATV is very convenient when for example: a model requires more DOWN elevator deflection than UP for equal inside and outside loops (with equal control stick

ATV.
MEMORY (PUSHBUTTON) ATV
This type of ATV is available on all eight channels. Servo travel is adjusted as outlined in the example below. NOTE: Memory ATV settings are retained in the transmitter memory circuit even when the power switch is turned OFF. They are lost however, if the transmitter Nicd battery nears full discharge or is removed for servicing.

AILERON DUAL RATE
• The aileron rate switch 14 has two D/R ON positions. Thus three different servo travel rates are available on aileron. Rates can be adjusted to suit varying aircraft and maneuver requirements.
Aileron dual rate trimmer (1)
This trimmer sets the aileron travel when the aileron dual rate switch 14 is set
to the dual ON I position.
Aileron dual rate trimmer 2 This trimmer sets the aileron travel when the aileron dual rate switch
14 is set to the dual ON 2 posi­tion. Trimmers [1] and [2] can adjust the aileron travel from 40% to 80% of the total travel. When the dual rate switch is set to ON, the servo throw can be set to an arbitary angle smaller than when the dual rate switch is OFF (normal) as shown in Fig. 37 . Use the throw matched to the aircraft and the maneuvers to be perform­ed.

•When the Aileron LINEAR/VTR Switch [3] is in the LINEAR position, servo travel is linear
and directly proportional to the deflection of the transmitter control stic k as shown in Fig. 42.
In the VTR position (Ail. D/R Switch 14 must
also be in D/R OFF pos.), servo maximum throw is unchanged. However servo tracking is the same
as when the rate switch is in the D/R I ON
position up to about 80% of the transmitter stick deflection. Servo throw then abruptly in­creases to the same deflection as when D/R Switch 14 is in D/R OFF position. Fig. 42 shows the servo movement curve when VTR is used.

•SUGGESTIONS ON ATV, D/R, AND VTR
POINTS TO REMEMBER (ATV, D/R, VTR)
•Servo maximum deflection is always determined by ATV. If no ATV is set, maximum travel is
governed by the servo itself and is approximately 45 degrees in each direction from neutral.
•When Dual Rate is ON, servo travel in each
direction is reduced by the same percentage
(adjustable using D/R trimmers). For example, in Fig. 43 one direction has been limited using
ATV. Both sides are reduced 20% when D/R is ON. In other words, the ratio of UP to Down will be maintained when D/R is ON or OFF.
• VTR operates only when D/R is set to OFF po­sition (LINEAR/VTR switch must al so be set to VTR position).
•Servo tracking is always LINEAR when Dual Rate is ON (regardless of LINEAR/VTR switch).
SUGGESTIONS
• VTR is useful when different throw rates are
desired for different portions of the same ma-
neuver or when there may be insufficient time between maneuvers for changing rate switches manually such as in the FAI F3A or "Turn-
around" Pattern event.
•When preparing to test fly a new model, if you are unsure as to the amount of Aileron deflec-
ti o n needed, set up as follows.
LINEAR/VTR switch 3. on LINEAR Aileron D/R I at best estimate of desired throw for normal flying or deflection speci­fied on aircraft p lans. Aileron D/R 2 less movement than D/R (1) D/R OFF set to provide somewhat more throw than specified. Set Ail. D/R Switch 14 to 1, position for
takeoff.
If aileron response is not comfortable, it can
easily be increased or decreased while air­borne.
• Try this set-up for AMA Pattern: Aileron LINEAR/VTR Switch [3] LINEAR. Adjust D/R I to give 3 rolls in approxi-
mately 5 seconds.
Use ATV to adjust for a fast roll rate when D/R Switch 14 is OFF .
Adjust D/R 2 for slow roll (1 roll in 5
seconds).

FS FUNCTION/HOLD FUNCTION
Fail Safe (FS) is a function which moves the servo
of each channel to a position preset (at the trans-
mitter) when an erroneous signal or continuous
strong noise is received for about 1 second or
longer. When the proper signal is lost or strong
interference received, the airborne system will operate in the HOLD mode for about 1 second before switching to the FS mode. When a normal signal is received again for about 1 second, FS is
released a ndnormal control resumes. The HOLD functionstops all servos selected (by button [47] at interference was received. When a normal signal is resumed, HOLD is released.

THROTTLE
The Throttle Trim Lever 19 affects the servo po­sition only when t he throttle control stick is in the
LOW (IDLE) position. HIGH throttle position remains unchanged. Adjustment of the throttle linkage is therefore very convenient.
Use a servo horn that allows slightly more throw than needed.
Set the maximum opening at
using Memory ATV (Page 18).
Use Memory ATV to set the extreme LOW position to prevent servo binding when the throttle screw. With the engine running, use ATL Throttle Trim Lever 19 to set the optimum idle speed.
A combination of FS and HOLD functions can be selected on each channel at the modeler's discre­tion. FS, HOLD, and SERVO TEST functions are oper­ated using three switches on the trimmer panel.

•AIRCRAFT WITH VARIABLE PITCH PROP
ADVANTAGES OF VARIABLE PITCH PROPELLER
The variable pitch propeller offers such advantages as:
1. The desired speed and p u l l can be adjusted.
2. Speed matched to the engine is obtained.
3. Low noise.
4. Air braking effect by
zero pitch.
5. Idling is unnecessary.

Pitch zero does not have an air braking affect. If the engine is running at a speed of 3000 ~ 4000 rpm, the air braking effect will not appear if the propeller diameter is too small. Adjust the throttle so the pitch is positive and the engine idles when switch II is set to the OFF position. Since lever 8 is also operative in this state, optimum pitch adjustment is possible.

VARIABLE PITCH PROPELLER AND ENGINE POW ER MATCHING IS ESSENTIAL FOR MAXIMUM PERFORMANCE
If
the throttle stick is operated quickly during flight, the engine will make an abnormal sound (sputter). If the engine sound remains unnatural,
the pitch control or throttle servo operation tim-
ing can be d el ayed.
When the t hr ottle lever is suddenly moved from a
high speed to a low speed, the throttle operates before the propeller pitch changes to zero. If the
throttle lever is moved from HIGH to SLOW, the
pitchwill change before the throttle operates.
Set the throttle delay time with trimmer [4] and the pitch delay time with trimmer [5] . This provides the same fe e li ng as fixed propeller ai rc ra ft andallows natural flight.
