S.BUS Servo Description of function of each parameter

*There are a function which can be used according to the kind of servo, and an impossible function.

• ID

Displays the ID of the servo whose parameters are to be read. It cannot be changed.

• Channel

Channel of the

• Reverse

The direction in which the servo rotates can be changed.

• Servo type

When “Retractable” is selected and the servo has been continuously stopped for 30 seconds, the dead band expands and unnecessary hold current due to external force is eliminated. When a new control signal enters, normal operation is resumed. When using the servo as a landing gear servo, select “Retractable”. Also adjust the servo travel to match the landing gear movement range.

• Soft Start

Restricts operation in the speciﬁed direction the instant the power is turned on. By using this setting, the ﬁrst initial movement when the power is turned on slowly moves the servo to the speciﬁed position.

• Stop Mode

The state of the servo when the servo input signal is lost can be speciﬁed. The "Hold" mode setting holds the servo in its last commanded position even if using AM or FM system.

• Smoother

This function changes smoothness of the servo operation relative to stick movement changes. Smooth setting is used for normal ﬂight. Select the "OFF" mode when quick operation is necessary such as 3D.

• Neutral Offset

The neutral position can be changed. When the neutral offset is large value, the servo's range of travel is restricted on one side.

• Speed Control

Speeds can be matched by specifying the operating speed. The speed of multiple servos can be matched without being affected by motor ﬂuctuations. This is effective for load torques below the maximum torque.

However, note that the maximum speed will not be exceed what the servo is capable of even if the servos operating voltage is increased.

• Dead band

The dead band angle at stopping can be speciﬁed.

[Relationship between dead band set value and servo operation]

Small → Dead band angle is small and the servo is immediately operated by a small signal change.

Large → Dead band angle is large and the servo does not operate at small signal changes.

(Note) If the dead band angle is too small, the servo will operate continuously and the current consumption will increase and the life of the servo will be shortened.

• Travel Adjust

The left and right travels centered about the neutral position can be set independently.

• Boost

The minimum current applied to the internal motor when starting the servo can be set. Since a small travel does not start the motor, it essentially feels like the dead band was expanded. The motor can be immediately started by adjusting the minimum current which can start the motor.

[Relationship between boost set value and servo operation]

Small → Motor reacts to a minute current and operation becomes smooth.

Large → Initial response improves and output torque increases. However, if the torque is too large,

operation will become rough.

• Boost ON/OFF

OFF : It is the boost ON at the time of low-speed operation.(In the case of usual)

ON : It is always the boost ON.(When quick operation is hope)

• Damper

The characteristic when the servo is stopped can be set.

When smaller than the standard value, the characteristic becomes an overshoot characteristic. If the value is larger than the standard value, the brake is applied before the stop position.

Especially, when a large load is applied, overshoot, etc. are suppressed by inertia and hunting may occur, depending on the conditions. If hunting (phenomena which cause the servo to oscillate) occurs even though the Dead Band, Stretcher, Boost and other parameters are suitable, adjust this parameter to a value larger than the initial value.

[Relationship between damper set value and servo operation]

Small → When you want to overshoot. Set so that hunting does not occur.

Large → When you want to operate so that braking is not applied. However, it will feel like the servo

(Note) If used in the hunting state, not only will the current consumption increase, but the life of the servo will also be shortened.

response has worsened.

• Stretcher

The servo hold characteristic can be set. The torque which attempts to return the servo to the target position when the current servo position has deviated from the target position can be adjusted.

This is used when stopping hunting, etc., but the holding characteristic changes as shown below.

[Relationship between stretcher and servo operation]

Small → Servo holding force becomes weaker.

Large → Servo holding force becomes stronger.

(Note) When this parameter is large, the current consumption increases.

• Buzzer

When the power supply of a servo is previously turned on at the time of a power supply injection without taking transmit of a transmitter, the buzzer sound of about 2.5 Hz continues sounding from a servo.

(Even when the transmit of a transmitter is taken out previously, a buzzer becomes until the signal of a servo is outputted normally, but it is not unusual.)

The transmitter has been turned OFF ahead of a servo power supply→ The buzzer sound of about 1.25 Hz continues sounding as servo power supply end failure alarm.

(

Do not insert or remove the servo connector while the receiver power is ON.　A buzzer may

sound by incorrect recognition.

Buzzer sound is generated by vibrating the motor of a servo.

＊

Since current is consumed and a servo generates heat, please do not operate the number more than needed or do not continue sounding a buzzer for a long time.

MODEL BASIC SETTING PROCEDURE

Airplane/glider basic setting procedure

1. Model addition and call

Initial setting assigns 1 model to the T18SZ transmitter. The Model Select function of the Linkage Menu is used to add models and to select models which are already set.

The data for up to 30 models can be saved to the transmitter. Data can also be saved to the optional SD card.

The currently selected model name is displayed at the top of the screen. Before flying and before changing any settings, always confirm the model name.

When a new model is added, the Model type select screen and System/Receiver ID setup screen automatically appear. Please be aware that the transmitter will stop transmitting when you change the model.

3. Fuselage linkage

Connect the ailerons, elevators, throttle, rudder, etc. in accordance with the model's instruction manual. For a description of the connection method, see the Receiver and Servos Connection.

Note: The channel assignment of the T18SZ is different from that of our existing systems. Note that even for the same "airplane model", when the wing type and tail type are different, the channel assignment may be different. (The channel assigned to each function can be checked at the Function menu of the Linkage Menu.)

● If the direction of the servo is incorrect, adjust

the direction with the Reverse function of the

Linkage Menu.

2. Model type selection

Select the model type matched to the aircraft with the Model Type select function of the Linkage Menu. For an airplane, select the model type from among the 2 types: airplane and glider. After the wing type is selected the tail type select screen is displayed. Select the tail type matched to the aircraft.

There are 13 wing types and 3 tail types for airplane and glider.

● Adjust the neutral position and control surface

angle with the linkage, and fine tune them with the Sub Trim and End Point functions

(angle adjustment). To protect the linkage, a

limit position can also be set with the End Point

function. The End Point function can adjust the

amount of up/down and left/right movement, limit, and servo speed of each channel.

4. Throttle cut setting

Throttle cut can be performed with one touch by a

switch without changing the throttle trim position.

Set throttle cut with the Throttle Cut function of the Linkage Menu. After activating the throttle cut function and selecting the switch, adjust the throttle position so that the carburetor becomes fully closed. For safety, the

6. AFR (D/R)

AFR function is used to adjust the throw and operation curve of the stick, lever, and switch functions for each flight condition. This is normally used after End Point

has dened the maximum throw directions.

8. Addition of ight conditions

The Condition Select function automatically allocates the Condition 1 (CONDIT1) for each model. Condition 1 is the default condition and is the only one active when a

new model type is dened.

If you want to add ight conditions, please refer to a

description of the COND. SELECT function.

*The Condition 1 is always on, and remains on until other

conditions are activated by switches.

*When a new condition is added, the model data of the

Condition 1 is automatically copied to the new condition.

*You can set the model data of new condition in the switch

ON state. However, if the group mode (GROUP) was selected in advance, the same data will be input at all the conditions. Select the single mode (SINGLE) and adjust only the condition you want to change. For Group/Single mode switching, refer to the description at the back of this manual.

*The Condition Delay can be programmed for each channel.

The Condition Delay is used to change the servo throw smoothly when switching conditions.

7. Airbrake

This function is used when an air brake is necessary

when taking off or diving, etc.

The preset elevators and aps (camber ap, brake ap)

offset amount can be activated by a switch.

The offset amount of the aileron, elevator, and flap servos can be adjusted as needed. Also the speed of the aileron, elevator, and flap servos can be adjusted. (IN side/OUT side) A delay can be set for each condition, and a Cut switch which will turn OFF the delay can be

Helicopter basic setting procedure

This section outlines examples of use of the helicopter functions of the T18SZ. Adjust the actual values, etc. to

match the fuselage used.

1. Model addition and call

Default setting assigns 1 model to the T18SZ. To add new models or to call a model already set, use the Model Select function of the Linkage Menu.

This is convenient when calling a model after registering the model names in advance. (The data of up to 30 models can be saved at the transmitter. Data can also be saved to the optional SD card.)

The currently called model is displayed at the top of the screen. Before flying and before changing

any settings, always conrm the model name.

When a new model is added, the Model Type Select screen and Frequency/Modulation mode/ Receiver ID setup screen automatically appear. Change, or check that they match the type, frequency, and receiver type of the model used.

2. Model type and swash type selection

If a different model type is already selected, select helicopter with the Model Type function of the Linkage Menu, and then select the swash type matched to the helicopter.

*The Model Type function automatically selects the

appropriate output channels, control functions, and mixing

functions for the chosen model type. Eight swash types are available for helicopters.

*For a description of the swash type selection, refer to the

MODEL TYPE function.

3. Flight condition addition

The transmitter can install up to eight ight conditions

per model.

The Condition Select function automatically allocates

ve conditions for helicopter.

(Initial setting)

● NORMAL

● IDLE UP1 (SW-E)

● IDLE UP2 (SW-E)

● IDLE UP3 (SW-F)

●HOLD (SW-G)

Note: Since you may accidentally activate the conditions that has not been setup during flight and this could cause a crash, delete the conditions not used.

*For a description of the condition deletion, refer to the

COND. SELECT function.

The NORMAL condition is always on, and remains on

until other conditions are activated by switches.

The priority is throttle hold/idle up 2/idle up 1/normal.

Throttle hold has the highest priority.

Add other conditions, as required.

The Condition Delay can be programmed for each channel. The Condition Delay is used to change the servo throw smoothly when switching conditions.

(General ight condition setting example)

● Normal: (Use initial setting conditions/operate

when switch OFF)

Use from engine starting to hovering.

● Idle up 1: (Operate at SW-E center)

● Adjust the neutral position at the linkage side

and ne tune with the Sub-Trim function and

End Point function (rudder angle adjustment).

To protect the linkage, a limit position can

also be set with the End Point function.

● Swash plate correction (Except H-1 mode)

*If any interactions are noticed, for a description of the

linkage correction function, please refer to the SWASH function.

5. Throttle/Pitch curve setting

This function adjusts the throttle or pitch operation curve in relation to the movement of the throttle stick for each condition.

Call the throttle curve of each condition with the condition select switch.

●Normal curve adjustment

Normal curve creates a basic throttle curve

centered near hovering. This curve is adjusted

together with the pitch curve (Normal) so that the engine speed is constant and up/down control is easiest.

●Idle up curve adjustment

The low side Throttle curve creates a curve

matched for aerobatics (loop, roll, 3D, etc.).

●Throttle hold curve adjustment

The curve is not used when performing auto rotation dives.

Conrm that the rate of the slowest position (0%) of the stick is 0% (initial setting).

Call the pitch curve of each condition with the condition select switch.

●Pitch curve (Normal)

Make the pitch at hovering approximately +5º~6º.

Set the pitch at hovering with the stick position at

the 50% point as the standard.

*Stability at hovering may be connected to the throttle curve.

Adjustment is easy by using the hovering throttle function and hovering pitch function together.

●Pitch curve (Idle up 1)

The idle up 1 pitch curve function creates a curve

matched to airborne ight. Set to -7º~+12º as standard.

●Pitch curve (Idle up 2)

The high side pitch setting is less than idle up 1. The standard is +8º.

●Pitch curve (Hold)

At auto rotation, use the maximum pitch at both

the high and low sides. [Pitch angle setting example]

Throttle hold: -7º~+12

6. AFR (D/R)

AFR (D/R) function is used to adjust the throw and operation curve of aileron, elevator and rudder for each condition.

*For throttle and pitch curve settings, refer to the above-

mentioned "Throttle/Pitch curve setting"

This is normally used after End Point has dened the maximum throw directions.

7. Gyro sensitivity and mode switching

The gyro sensitivity and mode switching function is

dedicated gyro mixing of the Model Menu, and can be

set for each condition.

●Normal condition (hovering): Gyro sensitivity

maximum

●Idle up 1/Idle up 2/Throttle hold: Gyro

sensitivity minimum

●However, at auto rotation of a tail-driven

helicopter, this function may not have any

effect at high gyro sensitivity.

do not use Pitch to RUD mixing.

Call the Pitch to RUD mixing function from the

Model Menu, and set the curve for each condition. (At initial setting, this function is in the "INH" state. To use it, set it to the "ON" state.)

Call the mixing curve of each condition with the

condition select switch.

1. A curve setting example is shown below.

●Pitch to RUD mixing curve (Normal)

Use the hovering system and set this curve to

match take off and landing and vertical climb at a constant speed.

*For this curve, use the initial setting [EXP1] curve type.

●Pitch to RUD mixing (Idle up 1)

Use this curve in 540º stall turn, loop, and rolling stall turn, and adjust it so the fuselage is facing

straight ahead when heading into the wind.

*For this curve, [EXP1] curve type can be used and the entire

curve can be lowered with the [Offset] function.

●Pitch to RUD mixing (Hold)

This function is set so that the fuselage is facing straight ahead at straight line auto rotation. The

pitch of the tail rotor becomes nearly 0º.

*For this curve, [EXP1] curve type can be used and the entire

curve can be lowered with the [Offset] function.

●Other settings

The mixing rise characteristic at pitch operation

can be adjusted. An acceleration function which

temporarily increases and decreases the mixing amount can be set.

8. Pitch to RUD mixing setting

Note: When using a GY601, GY502, GY401,

or other heading hold gyro, this Pitch to RUD

mixing should not be used. The reaction

torque is corrected at the gyro side. When

operating the gyro in the AVCS mode, the

mixed signal will cause neutral deviation

symptoms and the gyro will not operate

normally.

Use this function when you want to suppress the torque generated by the changes in the pitch and speed of the main rotor during pitch operation. Adjust it so that the nose does not swing in the rudder direction. However, when using a heading hold gyro like those shown below,

9. Throttle hold setting

*If throttle hold is necessary, please refer to the THR HOLD

function.

10. Throttle cut setting

Throttle cut provides an easy way to stop the engine, by flipping a switch with the throttle stick at idle. The action is not functional at high throttle to avoid accidental dead sticks. The switch’s location and direction must be chosen, as it defaults to NULL.

*With throttle stick at idle, adjust the cut position until the engine consistently shuts off, but throttle linkage is not binding.

11. Swash Mix corrects aileron, elevator and

pitch interaction

The swash mix function is used to correct the swash

plate in the aileron (Left/Right Cyclic) and elevator (Forward/Aft Cyclic) direction corresponding to each operation of each condition.

12. Throttle mixing setting

*If throttle mixing is necessary for a compensation for

slowing of engine speed caused by swash plate operation during aileron or elevator operation, please refer to the THROTTLE MIX function.

13. Other special mixings

●Pitch to Needle mixing

This mixing is used with engines with a construction

which allows needle control during ight (fuel-air mixture adjustment). A needle curve can be set.

The needle servo rise characteristics at throttle stick acceleration/deceleration operation can be

adjusted. (Acceleration function)

●Governor mixing

This mixing is dedicated governor mixing when a

governor is used. Up to 3 rates (speeds) can be

switched for each condition.
