1 FOREWORD

The GYA351 is a high performance, compact, and light weight AVCS gyro developed for model aircraft ailerons, especially two servos FLAPRON wing, control. Integrated sensor and control circuit make it easy to mount.
Servos: Gyro performance largely depends on the servo used. The faster and more responsive the servo, the higher the speed and the better the sensitivity and performance of the gyro.

2 SET CONTENTS

GYA351
The GYA351 comes with the following accessories:
Double-sided tape (3 sheets)

Features

AVCS used Forward, climb, descent, back, knife edge, and other flying attitudes are maintained even when the wind shifts. Therefore, since meeting rudder is almost completely unnecessary, flying is easy. At the same time, the gyro automatically corrects bad tendencies of the aircraft. SMM gyro sensor Newly developed very low drift SMM (Silicon Micro Machine) gyro sensor practically eliminates trim changes during flight. Remote gain and mode switching functions Remote gain function lets you switch the gyro gain from the transmitter. AVCS mode/Normal mode/Gyro OFF can also be switched from the transmitter. Integrated type, compact size, and light weight Compact size (27x27x20mm) and light weight (32g) have been achieved by the use of high density mounting technology. Conductive resin case improves EMC resistance (electrostatic, electromagnetic wave interference).

3 NAME AND FUNCTION OF EACH PART
Gyro gain trimmer (G GAIN) Monitor LED
Monitors the operating status of the GYA351. See the table below for the display contents. Adjusts the gyro gain. Gain adjustments are made from the transmitter. In this case, the value set with this trimmer becomes the reference and the gain can be adjusted by changing the servo deflection angle setting of the transmitter gain adjustment channel. When the trimmer is turned clockwise, the gain increases. Adjust the gain to the maximum value at which hunting does not occur.
Gyro direction of operation selector switch (ch1)(DIR.A) Gyro direction of operation selector switch (ch6)(DIR.F)
Selects the direction of operation of the gyro. If the servo moved when the fuselage was moved in the aileron axis direction and the servo moved to cancel this movement, the direction of operation is matched. If the aircraft is flown while the direction of operation is wrong, the gyro may apply reverse rudder and is very dangerous.
Control gain trimmer (C GAIN)
Adjusts the steering signal controlled variable. The effect of the rudder when the gyro is turned on can be adjusted. When the trimmer is turned clockwise, the controlled variable increases.

Servo output connector

Connects the corresponding servo.
Gain switching connector (red)
Gyro gain switching signal input connector. Connects to the receiver gain switching channel output connector. The signal from this connector is also used to switch the AVCS and Normal operation modes simultaneously with gain switching.

Ch6 input connector (black)
Connects to ch6 servo output connector of the receiver.

(Monitor LED display)

LED display Rapid flashing Steady light Off Slow flashing Double flash Single flash Gyro operation status Displayed while data is being initialized at power ON. Shows that the gyro is operating in the AVCS mode. Shows that the power is OFF, or the gyro is operating in the Normal mode. Displayed when a control signal is input from the transmitter. At this time, the servo does not operate. In the AVCS mode, displayed when the signal from the transmitter deviates from the neutral signal memorized at the gyro. Also displayed when a stick is operated. Displayed when the AVCS function is reset, and a neutral signal is sent to the servo. The LED flashes once when the gain selector switch was quickly switched between the Normal and AVCS positions three or more times and then left in the AVCS position, or when a transmitter stick was quickly moved to the left and right three or more times. After this display is per formed, the servo moves to the neutral position. This display also flashes when the operation direction or control selector switch was moved.
Ch1 input connector (black)
Connects to ch1 servo output connector of the receiver.

GYA351 operation modes

The GYA351 has two operations modes: AVCS mode and Normal mode.
Normal mode This mode performs general proportional control operation. For instance, it controls the gyro so that changes are countered when the attitude of the aircraft is changed by cross-wind, etc. AVCS mode This mode performs both proportional and integrated control operation The difference between Normal mode and AVCS mode operation is that whereas the Normal mode only counters changes in attitude, the AVCS mode returns to the original controlled variable simultaneously with countering changes in attitude. For example, during knife edge flying, aileron and elevator meeting rudder is normally necessary, but in the AVCS mode, meeting rudder is performed automatically by the gyro. Also, in the AVCS mode, high-speed control is possible, but when the usage method is incorrect, unintended operation may be performed. Before use, gain a thorough understanding by reading the Usage Precautions and Operation Instructions.
4 GAIN AND OPERATION MODE SETTING
The relationship between the travel adjustment functions (ATV, AFR) settings and gyro gain when the gyro gain is switched using the transmitter switching channel is shown below.

AVCS mode gain setting:

This figure shows the case when the gain setting channel reverse function is set to Normal. When this function is set to Reverse, the switch directions are reversed. (When Futaba proportional set used) When the ATVB rate is 40% or more, the gyro operates in the AVCS mode. The actual gyro gain changes based on the gyro gain trimmer setting of the gyro itself. When the gyro gain trimmer is set to 100%, the gyro gain becomes 100% at 100% ATV rate and becomes 50% at 70% ATV rate. When the gyro gain trimmer is set to 50%, when the ATV rate is 100%, the gyro gain becomes 50% and when the ATV rate is 70%, the gyro gain becomes 25%.

5 OPERATION INSTRUCTIONS

Mount and adjust the GYA351 as described below.
3. Trimmer setting (Initial)
Set the gyro gain trimmer to about the 50% position. Set the control gain trimmer to about the 100% position.

Gyro Mounting Method

Make a gyro bed so that the bottom of the gyro body is perpendicular to the direction of the axis to be controlled and securely install the gyro with the accessory double-sided sponge tape at a position at which vibrations are minimal.
If this axis changes, the gyro also corresponds to linkage of other axis.

4. Power ON procedure

Turn on the transmitter power, then turn on the receiver and gyro power. After the gyro power is turned on, initialization is automatically performed for about three seconds. Never move the aircraft during this period. During initialization, the gyro monitor LED flashes.
5. Gyro direction of operation check
Tilt the aircraft about the aileron axis, and check if the gyro applies rudder in the direction opposite the direction of tilt. If the rudder moves in the opposite direction switch the gyro direction of operation selector switch.

Flight adjustments 1. Power ON procedure
Turn on the transmitter power, then turn on the receiver and gyro power. After the gyro power is turned on, initialization is automatically performed for about three seconds. Never move the aircraft during this period.
2. Trimming Usage Precautions
When taking off and landing, always switch to the Normal mode. Taking off and landing in the AVCS mode is dangerous. When using an air brake, use the gyro in the Normal mode. If used in the AVCS mode, the aircraft will roll. When the gyro is ON, the servo operating angle increases. Increase the travel width of the flight control surfaces so that they will not strike the linkage even when the servo is operated to its maximum deflection angle. Always use the miniature screwdriver supplied to operate the GYA350 selector switches and trimmers. Do not apply excessive force.
Fly and trim the aircraft. If there is a large mechanical deviation, correct the linkage. Connect the linkage so that the servo horns are as close to the center position as possible and the transmitter trimmers are also at the center position.

3. Gyro gain adjustment

When the servo hunts, the gyro gain is too high. Lower the gain with the gyro gain trimmer until the hunting stops. The gyro will display best performance at a gain just before Gyro gain trimmer hunting occurs. Perform trimming by flying the aircraft (G GAIN) repeatedly.
4. Rudder effect adjustment

Control gain trimmer

Beginner setting
(When there is no vacant receiver channel)
(C GAIN) Use the transmitter steering angle adjustment function to adjust the rudder effect. However, when the rudder effect is substantially different from that when the gyro was not mounted, adjust it with the control gain trimmer. When the gyro is turned on, the rudder will feel sluggish. Adjust the control gain so that the rudder effect matches the rudder effect when the stick is set to its maximum position. When the control gain is increased, the rudder effect increases.

Use this setting method when there is no vacant receiver channel. Use the GYA351 in the Normal mode only.

Standard Setting

(Setting using all GYA351 functions)
Mounting to fuselage and initial setting 1. Gyro mounting
Mount the gyro to the axis in accordance with "Gyro Mounting Method".
This standard setting controls gain switching and AVCS/ Normal gyro operation mode switching from the transmitter. However, when using the GYA351 with its GYA350 sister product, and mounting gyros in three axis, three vacant channels are necessary for gain and operation mode switching. When there are not enough vacant channels, do not connect the gain switching connector and operate the gyro in the Normal mode only. The gain of the gyros of two axes can also be switched simultaneously by using a branch cord.

5. Power ON procedure

Turn on the transmitter power, then turn on the receiver and gyro power. Initialization is performed automatically for about three seconds after the gyro power comes on. Do not move the aircraft during this period. During initialization, the gyro monitor LED flashes. When the gain selector switch is set to the AVCS position, the monitor LED changes to a steady light. When the gain selector switch is set to the Normal position, the LED goes off.

(Gain setting with T8UAPS example 3)
The following describes how to use CH7 to switch the aileron and elevator gain and CH8 to switch the rudder axis gain. (When GYA350 being used in the rudder and elevator.) The aileron and elevator gyros gain switching connector is connected to receiver CH7 by branch cord. When air brake is ON, the aileron and elevator axis gyros must be set to the Normal mode.
Flight adjustment 1. Power ON procedure
Turn on the transmitter power, then turn on the receiver and gyro power. Initialization is performed automatically for about three seconds after the gyro power comes on. Do not move the aircraft during this period.
6. Switch to the AVCS or Normal mode, as desired.
In the AVCS mode, meeting rudder is seldom necessary because trim changes during knife edge and upside-down flight are compensated for by the gyro. Conversely, when the aircraft enters a stall condition in the low speed state, the gyro continues to apply correction rudder and the aircraft may enter an unintended attitude. To avoid stalling in such a state, return to normal attitude as soon as possible by increasing engine power and applying reverse rudder, or switch the gyro to the Normal mode.

2. Trim adjustment

Set the gyro gain switch to the Normal or OFF position. The monitor LED goes off. Fly and trim the aircraft in this state. When the mechanical deviation is large, correct the linkage. Connect the linkage so that the servo horn and transmitter trimmers are in the center position.

Using AVCS correctly

The AVCS type gyro controls the attitude of the aircraft by constantly comparing the transmitter operation signals and the gyro internal reference signal (transmitter neutral signal). Therefore, for the AVCS function to operate normally, the rudder neutral signal must be memorized at the gyro before flight.
When the servo hunts, the gyro gain is too high. Lower the gyro gain until the hunting stops. The gyro displays top performance at a gain just before hunting begins. Perform trimming by flying the aircraft repeatedly. Adjust the gain by raising and lowering the transmitter ATV or mixing rate.
Neutral signal memorization

There are two methods of memorizing the neutral signal. [Method 1] When the gyro power is turned on, the signal received from the transmitter at that time is assumed to be the neutral signal and is memorized at the gyro. The gyro is normally used in this state. [Method 2] The neutral position can also be memorized by rapidly switching the transmitter gain switch between the AVCS and Normal positions at least three times at an interval of within one second. In this case, the monitor LED flashes once to show that memorization is complete. When the trim was changed during flight, the memorized neutral position can be updated to the current neutral position by repeating this operation. When this performing this operation, kept the stick in the neutral position.
Use the transmitter deflection angle adjustment function to adjust the rudder effect. However, when the rudder effect is substantially different from that when the gyro is installed, adjust it using the control gain trimmer. When the gyro is turned on, the rudder will feel sluggish. Adjust the control gain to match the rudder effect when the stick is set to its maximum position. When the control gain adjustment amount increases, the rudder effect increases. Adjust the linkage so that use is possible at a transmitter deflection angle setting of 70% or more.
5. AVCS side neutral data memorization
After landing the aircraft, set the gain switch to the AVCS position and turn on the gyro power again and memorize the AVCS mode neutral data at the gyro. When using flight conditions, verify that the gyro monitor LED lights under all the flight conditions used. If the LED flashes twice, trim of that flight condition has changed. Repeat transmitter trim adjustment. This ends AVCS side setting.

Neutral check method

In the AVCS mode, the servo does not return to the neutral position even though the stick is returned to neutral. When you want to check the servo neutral position during linkage neutral check, etc., set the gain switch to the Normal position, or quickly move the transmitter stick to the left and right at least three times and immediately return the stick to the neutral position. A dead zone is produced in servo operation relative to stick operation. However, this is because the stick control gain rises and is not an abnormality.

Mounting Precautions

Always use the accessory sensor tape to install the gyro to the fuselage.
This is necessary to securely fasten the gyro to the fuselage so that operation of the gyro does not transmit unwanted fuselage vibrations directly to the sensor.
and turn on the transmitter power switch, then turn on the gyro power.
When using the gyro in the AVCS mode, turn off mixing.
For example, if elevator down mixing is used by the air brake, the gyro will judge that an elevator down signal was received and will cause the aircraft to dive. In the AVCS mode, the gyro automatically changes the trim and, therefore, these mixings are unnecessary. When mixing is necessary, set so that the gyro enters the Normal mode when mixing is ON.
Do not operate the trim while flying in the AVCS mode.
When the power is turned on, the GYA351 assumes that the stick is in the neutral position. If the trim is moved during flight, the neutral position will change.
When mounting the gyro, provide a little surplus so that the gyro connection cables are not too taut.
If the gyro cables are too taut, the gyro will not display its full performance. If the gyro peels, control will be lost and result in a dangerous situation.
Avoid sudden temperature changes.
Sudden temperature changes will cause the neutral position to change. For instance, do not fly the model immediately after removing it from inside a heated vehicle in the winter and an air conditioned vehicle in the summer. Let the model stand for about 10 minutes to allow the temperature inside the gyro to stabilize before turning on the power. Also, consider sudden temperature changes when the gyro is exposed to direct sunlight or is installed near the engine. Take measures so that the gyro is not exposed to direct sunlight.
Check the operating time of the receiver, gyro, and servo batteries at the adjustment stage and decide the number of remaining flights while allowing a margin.
When using the gyro with a airplane, install the GYA351 at least 10cm from the drive motor and at least 2 cm from the servo.
The drive motor etc. generates strong electromagnetic noise. This noise may interfere with the gyro sensor and cause erroneous operation.
Fuselage Maintenance Precautions
Do not turn the sensitivity trimmer with too much force.
The trimmer may break. Always use the miniature screwdriver supplied to make adjustments.
Do not stall the aircraft.
When the aircraft enters the stall condition, and the gyro tries to maintain its original attitude by applying full rudder. This results in assisting the stall. If the nose remains up and the aircraft stalls when landing, etc., the gyro will try to maintain that attitude by applying more up elevator. To avoid this danger, when taking off and landing, use the gyro in the Normal mode.

Mount the GYA351 so that metals or other conductive objects do not touch the gyro case.
The GYA351 uses a conductive resin case to reduce electromagnetic interference. Because the surface of the case is conductive, metal objects may cause a short circuit.
Service the fuselage with a little vibration as possible.
Fuselage vibration has a very adverse effect on gyro performance.
Insert the connectors fully.
If a connector works loose due to vibration during flight, control may be lost and result in a dangerous situation.
Do not use the AVCS mode when taking off and landing.
From the standpoint of the operation characteristics, taking off and landing in the AVCS mode is dangerous. When taking off and landing, use the gyro in the normal mode.
Always check the direction of operation of the servos.
If you attempt to fly the model when a servo operates in the wrong direction, the fuselage will spin in a fixed direction and enter an extremely dangerous state.

Special Markings

Pay special attention to the safety at the parts of this manual that are indicated by the following marks. Mark Meaning Procedures which may lead to a dangerous condition and cause death or serious injury to the user if not carried out properly. Procedures which may lead to a dangerous condition or cause death or serious injury to the user if not carried out properly, or procedures where the probability of superficial injury or physical damage is high. Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or physical damage, if not carried out properly.

Operation Precautions

Never move the fuselage for about 3 seconds after turning on the gyro power. (when using in the AVCS mode)
Since the data inside the gyro is automatically initialized as soon as the power is turned on, if the fuselage is moved, the neutral position will change. If this occurs, turn the power off and on again. When turning on the power, set the transmitter switch to the AVCS position

MODEL SELECT

This function is used to load the settings of the desired model into the T12FGs memory. The settings may be selected from either the transmitters built-in memory or a SD card (32MB1GB). Remember that up to 30 model memories are available in the transmitter. The name of the model stored in the transmitter and the SD card may be changed. This can be very useful to tell different models settings apart. Each model name can be as long as 8 characters, and the model name always appears in the display screen. The Copy function is used to copy one set of model data into a second memory within the transmitter and the SD card. It may be used for getting a head-start on setting up models with almost the same settings (only complete model from scratch). Also, this function may be used to make a backup copy of a model setup before any changes are made.

Neutral Point At your linkages, if the servo horn deviates from a perpendicular position at neutral, the linkage compensation functions in this menu may not compensate effectively. To correct this use the Neutral Point function. This will move the neutral point of the servos to the actual perpendicular position. However, this adjustment changes only the axis point of the compensation functions in this menu, and does not affect the neutral position of other functions. Swash AFR Swash AFR function reduces/increases/reverses the rate (travel) of the aileron, elevator and collective pitch functions, by adjusting or reversing the motion of all servos involved in that function, only when using that function. Mixing Rate This compensation mixing is used to correct the tendency of the swash-plate for each control. The following compensation mixing is possible; PIT to AIL, PIT to ELE, AIL to PIT, ELE to AIL, and ELE to PIT (HR3 mode.) It adjusts the swashplate to operate correctly for each control using the corresponding compensation mixing. Linkage Compensation This compensation mixing is used to correct the tendency of the swash-plate for pitch control at low pitch and high pitch. Speed Compensation This function is used to cancel the reaction that is generated by the difference of the operation amount of each servo when the swash-plate moves.

A D/R curve which can be switched with a switch, etc. can also be added. Program mixing which can be freely customized. Up to 10 mixes can be used for each condition.
