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.

ADJUSTMENTS AND FLIGHT TECHNIQUES

•BASIC LINKAGES AND INSTALLATION

The FP-8SSAP 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. 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 in to 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 direction of travel in relation to stick movement is correct. If the direction of travel is reversed, use the servo reversing switches to correct.

• When installing the switch harness, cut a retangu-. lar 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 install the switch

inside the fuselage and attach a piece of wire to the switch so that it can be operated from outside

• Use the rubber bands wrapped around the receiver to hold the servo and switch leads.

• Even though th e receiver antenna may appear to be too long, do not sh ort en it or fold it back.

• Be alert for possible electrical noise. This system has nois e rejection circuits, however noiseless parts are recommended.

•Operate each servo to its full throw and check 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 l ever 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.

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.

•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 stick as shown in Fig. 32.

•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 i n each d i rection 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. 33 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 also be se t to VTR position).

•Servo tracking is always LINEAR when Dual

Rate is ON (regardless of LINEAR/VTR switch).

Fig.

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-

tio n needed, s e t up as follows.

1 LINEAR/VTR switch [3] on LINEAR 2 Aileron D/R I at best estimate of desired

throw for normal flying or deflection speci-

fied on aircraft plans. 3 Aileron D/R 2 less movement than D/R (1) 4 D/R OFF set to provide somewhat more

throw than specified. 5 Set Ail. D/R Switch 14 to (1) position for

6 If aileron response is not comfortable, it can

easily be increased or decreased while airborne.

Try this set-up for AMA Pattern:

1 Aileron LINEAR/VTR Switch [U set to

2 Adjust D/R (1) to give 3 rolls in approxi-

3 Use ATV to adjust for a fast roll rate when

D/R Switch 14 is OFF.

4 Adjust D/R 2 for slow roll (1 roll in 5

seconds).

Fail Safe (FS) is a function which moves the servo of each channel to a position preset (at the transmitter) 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

•AIRCRAFT WITH VARIABLE PITCH PROP

ADVANTAGES OF VA R IABLE PITCH PROPELLEJB

Matching of the variable pitch propeller to the di gital proportional RC set is essential. Improper use is extremely dangerous. Therefore, read t his section carefully. Connect the pitch control servo to channel 8. A variable pitch propeller can be adequately controlled by a common servo. Handle the servo the same as any other servo. Install the servo and linkage as specified by the manufacturer. (Note) This section explains how to use a

NOTE:

When lowering lever 8 , be careful that the pitch does not go negative. This is adjusted during flight.

For example, flight is affected by the temperature,

air pressure, wind, and other conditions. Use this

lever adjusting the speed, pull, etc. to your liking. Also select the engine tone quality by adjusting the propeller pitch. Make quiet flights by fine adjusting the propeller pitch. Next, adjust the throttle. First, set switch II to the OFF position. Adjust the engine idling speed to 2,200~2,500 rpm with the throttle trim lever

set the throttle lever to the maximum slow (zero

NOTES:

• The pitch always becomes maximum when the throttle switch is set to HIGH.

• The speed cannot be increased with the idle up lever 9 when the propeller pitch is zero.

• Best result is often obtained by making the tuned pipe longer.

VARIABLE PITCH PROPELLER AND ENGINE POWER 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 delayed.

When the throttle 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

pitch will change before th e throttle operates. Set the throttle delay time with trimmer [4] and the pitch delay time with trimmer [5]. This provides the same feeling as fixed propeller aircraft and allows natural flight.
