INSTRUCTION MANUAL 1 FOREWORD
The GYA352 is a high performance, compact, and light weight AVCS gyro developed for model airplane aileron, elevator, or rudder control. Two of these surfaces (axis) can be controlled by GYA352. Integrated sensor and control circuit simplifies mounting in the aircraft.
2 SET CONTENTS Double-sided tape
The GYA352 comes with the following accessories:

(3 sheets)

Features
Two axis control type (X-axis/Y-axis) Two axis of aileron, elevator or rudder can be simultaneously controlled by GYA352. ( For aileron, always use X-axis.) Built-in gyro mixing for Elevon/V-tail wing 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 (43x30x30.5mm) and light weight (49.5g) have been achieved by the use of high density mounting technology. Conductive resin case improves EMC resistance (electrostatic, electromagnetic wave interference).

GYA352 Ratings :

(Integrated sensor / two axis control type AVCS rate gyro) Control system: Digital advanced PI (Proportional Integration) control Gyro sensor: SMM (Silicon Micro Machine) system vibration gyro Operating voltage: +4 to +6VDC Dimensions: 43 x 30 x 30.5mm Weight: 49.5g (including connector) Functions: Gyro operation direction switch, Mixing switch, Gyro gain trimmer, and Control gain trimmer

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.
3 NAME AND FUNCTION OF EACH PART
Mixing on/off switch (ALV)
Turns on or off the gyro mixing for Elevon/V-tail wing. When using the gyro mixng, this switch is set to the ON position. When not using the gyro mixng, this switch is set to the OFF position.

Monitor LED

Monitors the operating status of the GYA352. See the table below for the display contents.
Control selector switch (CNT.X)
Selects to match the flight control surface to be controlled (X-axis side). When using the GYA352 to control the ailerons, this switch is set to the AIL position. When using the GYA352 to control the elevator or rudder, this switch is set to the ELV position.

Servo output connector

Connects the corresponding servo. (X-axis output/Y-axis output)
Gyro direction of operation selector switch (DIR.X, DIR.Y)
Selects the direction of operation of the gyro. If the rudder moved when the fuselage was moved in the gyro control axis direction and the rudder 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. (X-axis trimmer/Y-axis trimmer)
Servo input connector (black)
Connects to the corresponding servo output connector of the receiver. (X-axis connector/Y-axis connector)
Gyro Gain trimmer (G GAIN)
Adjusts the gyro gain. Adjust the gain to the maximum value at which hunting does not occur. The gain becomes 0 in the center. When Gain Switching connector is connected in the receiver, the gain adjustment is made from the transmitter. In this case, adjust within the A side. The value set with this trimmer becomes the reference. The gain can be adjusted by changing the servo deflection angle setting of the transmitter gain adjustment channel. When the gain adjustment is made only this trimmer, adjust within the N side. In this case, the gyro operates in the normal mode only. (X-axis trimmer/Y-axis trimmer)
Gain switching connector (remote gain input)(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. Since this connector is a single signal wire, do not pull on it forcefully. (X-axis connector/Y-axis connector)

GYA352 operation modes

The GYA352 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, END POINT) 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) (in case of "A" side of the Gyro Gain trimmer) When the ATV_B 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%.

Normal mode gain setting:
(in case of "A" side of the Gyro Gain trimmer) When the ATV_A rate is 40% or more, the gyro operates in the Normal mode. The gyro gain setting can be adjusted the same as in the AVCS mode.
When 100% set When 50% set (at the "A" side) (at the "A" side) (Gyro Gain trimmer position)
When gain switching from transmitter function not used:
The gyro gain switching connector is not connected to the receiver. In this case, when Gyro Gain trimmer is set to "A"/"B" side, the gyro operates in the AVCS/ normal mode severally. The gyro gain is set using the Gyro Gain trimmer.
When Gyro Gain trimmer is set to the "N" side, the gyro operates in the normal mode at both side of the switch directions.

5 OPERATION INSTRUCTIONS

Mount and adjust the GYA352 as described below.

Beginner setting

(When there is no vacant receiver channel)

Gyro Mounting Method

Make a gyro bed so that the bottom of the gyro body is perpendicular to the direction of the axis (X-axis, Y-axis) to be controlled and securely install the gyro with the accessory double-sided sponge tape at a position which vibrations are minimal.
If this axis changes, the gyro also responds to the changes of other axis. In order to raise attachment intensity, always fix two bottoms of the gyro body to fuselage with two double-sided sponge tapes.
Use this setting method when there is no vacant receiver channel. Use the GYA352 in the Normal mode only.
Mounting to fuselage and initial setting 1. Gyro mounting
Mount the gyro to the axis you want to control in accordance with "Gyro Mounting Method".

Aileron control

When the gyro is used for aileron control, always use the X-axis side and set Control Selector switch to the "AIL" side. Aileron axis
5. Operation mode selection

Usage Precautions

When taking off and landing, always switch to the Normal mode. Taking off and landing in the AVCS mode is dangerous. We recommend that you use the rudder control gyro in the Normal mode. In the AVCS mode, rudder operation is necessary when turning to prevent weathervaneing. Use the gyro in the Normal mode unless you are an expert in rudder operation. 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 GYA352 selector switches and trimmers. Do not apply excessive force.
When using the gyro mixng for Elevon/V-tail wing, this switch is set to the ON position. In this case, do not use the transmitter mixing function for Elevon/V-tail wing. In case of Elevon wing, always use the X-axis for the aileron control and the Y-axis for the elevator control. In case of V-tail wing, always use the X-axis for the rudder control and the Y-axis for the elevator control. The linkage of two servos must be symmetrical. If not, the gyro will operate in the wrong direction and result in a dangerous situation. When not using the gyro mixng, this switch is set to the OFF position.

6. 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 green.

7. Gyro direction of operation check
Tilt the aircraft about the controlled 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. DIR.X Gyro direction of operation selector switch DIR.Y
Flight adjustments 1. Power ON procedure

The following describes how to use CH7 to switch the X-axis gain and CH8 to switch the Y-axis gain.
(T8UAPS) (T9CAP) 1.Call the transmitter P-MIX1 screen, and make the following settings: - Activate P-MIX1. - Set master channel to OFS(OFST). - Set slave channel to CH7(AUX1). - Set mixing rate to +70%. - Select switch SW-E. - Select switch direction DOWN.

2. Trimming

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 hunting occurs. Perform trimming by flying the aircraft repeatedly.
2.Call the transmitter P-MIX2 screen, and make the following settings: - Activate P-MIX2. - Set master channel to OFS(OFST). - Set slave channel to CH7(AUX1). - Set the mixing rate to -70%. - Select switch SW-E. - Select switch direction UP. (SW-E) 3.Lock the transmitter CH7 knob in the 0% position. This sets the X-axis gyro gain to 50%.
When SW-E is in the forward, center, and backward positions, the GYA352 operates in the AVCS, OFF, and Normal modes, respectively.
4. Rudder effect adjustment
Use the transmitter steering angle adjustment function to adjust the rudder effect. Control Gain However, when the rudder effect is substantially different trimmer from that when the gyro was not mounted, adjust it with the (C GAIN) 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 rudder stick is set to its maximum position. When the control gain is increased, the rudder effect increases.

Set the gain as described below.
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 trims 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. Control gain trimmer (C GAIN) 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.
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.
5. AVCS side neutral data memorization
The neutral data can be memorized by following process. After landing the aircraft, set the rudder stick to the neutral position and rapidly switch the transmitter gain switch between the AVCS and Normal positions at least three times at an interval of within one second and then set the gain switch to the AVCS position. In this case, the monitor LED flashes once to show that memorization is complete. The neutral data can also be memorized by setting the gain switch to the AVCS position and turnning on the gyro power again. 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.
Dead zone of servo operation
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 GYA352 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 GYA352 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.
Mount the GYA352 so that metals or other conductive objects do not touch the gyro case.
The GYA352 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

Note the small numbers (1, 2, 3, 4) molded into each arm on the Futaba 4-arm servo arms. The numbers indicate how many degrees each arm is off from 90 degrees to correct for minute manufacturing deviations from servo to servo.
To center the servos, connect them to the receiver and turn on the transmitter and receiver. Center the trims on the transmitter, then find the arm that will be perpendicular to the pushrod when placed on the servo.
After the servos are installed, operate each servo over its full travel and check that the pushrods and servo arms do not bind or contact each other. Also make sure the controls do not require excess force to operate. If there is an objectionable buzzing sound coming from a servo, there is probably too much resistance in the control. Find and correct the problem. Even if there is no servo damage, excess battery drain will result. Use the mounting plate on the side of the fuselage opposite the engine exhaust, and where it wont be inadvertently turned on or off during handling or storage. Be certain the switch moves without restriction and snaps from ON to OFF, and that the cutout allows full motion of the switch in both directions. When you install the switch harness to the helicopter, please use the switch cover. Generally sandwich the frame between the switch and switch cover and securely tighten the screws. Different models might require different installations. If so, please follow the model's instruction manual. To prevent the servo lead wires from being broken by vibration during slightly and fasten it at suitable points. In addition, periodically check the wire during daily maintenance.
Fasten about 5-10cm from the servo outlet so that the lead wire is neat.

These receivers incorporate two separate antennas into their design which enables them *Must be kept as straight as possible. to receive the radio frequency transmission at two different locations. Futaba's dual antenna diversity then seamlessly selects the best signal reception between these antennas to ensure that there is no loss of signal. To obtain the best results of the diversity function, please refer to the following instructions:

LOW BATTERY ERROR: Warning sound: Continuous beep until transmitter is powered off. The LOW BATTERY warning is displayed when the transmitter battery voltage drops below 8.5V.
Land your model as soon as possible before loss of control due to a dead battery.
MIXER ALERT WARNING: Warning sound: 5 Beeps (repeated until problem resolved or overridden) The MIXER ALERT warning is displayed to alert you whenever you turn on the transmitter with any of the mixing switches active. This warning will disappear when the offending switch or control is deactivated. Switches for which warnings will be issued at power-up are listed below: :Throttle cut, idle-down, snap roll, airbrake GLID ACRO HELI:Throttle cut, throttle hold, idle-up If turning a switch OFF does not stop the mixing warning: When the warning does not stop even when the mixing switch indicated by the warning display on the screen is turned off, the functions described previously probably use the same switch and the OFF direction setting is reversed. In short, one of the mixings described above is not in the OFF state. In this case, reset the warning display by pressing CURSOR LEVER. Next, change one of the switch settings of the duplicated mixings. BACKUP ERROR: Warning sound: 4 beeps (repeated continuously) The BACKUP ERROR warning occurs when the transmitter memory is lost for any reason. If this occurs, all of the data will be reset when the power is turned on again. [Note] At this warning display, the transmitter transmits in 2.4G-10CH mode even if the set-up mode is 2.4G-7CH mode. Do not fly when this message is displayed: all programming has been erased and is not available. Return your transmitter to Futaba for service.
MEMORY MODULE INITIALIZE DISPLAY This warning appears when an (optional) CAMPac MODE BUTTON is pressed, initialization of the module begins, after which the memory module can be used. Once the module is initialized, the display will not appear again. The 10C CANNOT convert data from other radio types (i.e. 8U, 9Z). Installation of a CAMPac with data from another radio type will result in reinitialization of the CAMPac and loss of all data. RF ERROR: Warning sound: A single long beep. The single beep lets you know that the RF output has stopped for any reason. The blue RF light also goes out. Return your transmitter to Futaba for service.

Logic switch selection (LOGIC SW): The various functions in the T10CG can be selected by switch. The Logic switch can be assigned to the following functions: THR-CUT, IDLE DOWN, AUX-CH, TIMER, PROG. MIX, AIRBRAKE, ELEV-FLAP, and AILEFLAP functions. The logic switch can activate functions by two switches combinations. It is also possible to select from 2 types of logic, either AND or OR, can be selected. Adjustability: Three logic switches can be used.

Examples: Adjust the throttle high end to avoid binding at the carburetor, and low end to allow for proper carburetor closure. END POINT spoilers. Retract servos are not proportional. Changing END POINT will not adjust the servo. END POINT adjusts only the individual servo. It will have no effect on any other servo that is operated in conjunction with this servo via mix or preset programming such as FLAPERON, AILEVATOR, etc. This is so that each individual servo can be FLAPERON, make the adjustments in that function's controls. For CCPM helicopters, adjust the total travel of the function, such as collective pitch, in SWASH AFR. Adjust the linkage or the END POINT? It is nearly always best to adjust your linkages to get as close as possible prior to utilizing END POINT. The higher the END POINT setting, the better position accuracy and the more servo power available at nearly any position (except if using digital servos). Higher END POINT values also mean longer travel time to reach the desired position, as you are utilizing more of the servo's total travel. (For example, using 50% END POINT would give you only half the steps of servo travel, meaning every click of trim has twice the effect and the servo gets there in half the time). end point (and moving the linkage) = torque, accuracy, but transit time to get there. end point (instead of adjusting linkages) = travel time, but torque, accuracy. GOAL of EXAMPLE: STEPS: Decrease the flap servo throw in the Open END POINT function. upward direction to 5% to allow travel to 85% to prevent binding.

Engine idle management: IDLE-DOWN and THR-CUT: functions which work with the digital THROTTLE TRIM to provide a simple, consistent means of engine operation. No more fussing with getting trim in just the right spot for landings or takeoffs! For additional engine adjustments, see THROTTLE-NEEDLE (p. 65) and THROTTLE DELAY (p. 66). IDLE-DOWN (ACRO only): lowers the engine idle for: sitting on the runway prior to take off, stalls and spins, and landings.
Important note: The IDLE-DOWN function is not normally used when starting the engine, and its accidental operation may keep your engine from starting. The 10CG warns that IDLE-DOWN is on when the transmitter is turned on. Be sure to turn off the function, or override the warning by pressing CURSOR lever if you intended the function to be on.

Note that the CH9-10 functions are only visible in the AUX-CH screen when 2.4H-10CH modulation is selected. Channels 8-10 are not supported in 2.4G-7CH modulation.
Adjustability: Channels 5-8 may be assigned to any SWITCH (A-H), LOGIC SWITCH (Lsw1-Lsw3), slider [VR(D) and VR(E)], or knob [VR(A-C)] for example, moving flaps to a switch or slider, but not the primary control sticks (use programmable mixes to do so, p. 68). (GLID 1A+1F only): Channel 6 may be assigned to Airbrake control stick (STK-ARBK). Channels 9-10 may be assigned to any SWITCH (A-H), LOGIC SWITCH (Lsw1-Lsw3) and the servo direction may be changed. Multiple channels may be assigned to the same switch, slider or knob; Channels set to "NULL" are only controlled by mixes. (Ex: utilizing 2 channels for 2 rudder servos. See mixes, p. 68.)

TRAINER: for training novice pilots with optional trainer cord connecting 2 transmitters. The instructor has several levels of controllability. Adjustability: NORM: When the TRAINER SWITCH is ON, the channel set to this mode can be controlled by the student. The set channel is controlled according to any programming set at the student's transmitter. FUNC: When the TRAINER SWITCH is ON, the channel set to this mode can be controlled by the student, controlled according to any mixing set at the instructor's transmitter. MIX: When the TRAINER SWITCH is ON, the channel set to this mode can be controlled by both the student and the instructor, controlled according to any mixing set at the instructor's transmitter. And the student's mixing rate is adjustable. (default 30%) [Note] However, it becomes invalid even if the channel is not in a student's transmitter. The channel serves as operation by the instructor's transmitter automatically. OFF: The channel set to this mode cannot be controlled by the student even when the TRAINER SWITCH is ON. The set channel is controlled by the instructor only, even when the TRAINER SWITCH is ON. SWITCH: controlled by spring-loaded SWITCH F (10CAG) or H (10CHG) only. Not assignable. Compatibility: The 10CG may be master or student with any Futaba transmitter compatible with the cord. Simply plug the optional trainer cord (For 10CG series, sold separately) into the trainer connection on each transmitter, and follow the guidelines below. Examples: FUNC, 5-channel helicopter practice is possible with a 4-channel transmitter. Set up the model in a second transmitter, use NORM mode to quickly and safely check proper operation of all functions, then allow Using NORM mode, set lower throws, different exponentials, even different auxiliary channel settings on the student radio (if it has these features). To ease the learning curve, elevator and aileron may be set to the NORM or FUNC mode, with the other channels set to OFF and controlled by the instructor. Precautions: NEVER turn on the student's transmitter power. ALWAYS set the student transmitter modulation mode to PPM. As for a T10CG transmitter, PPM signal is always sent by the trainer jack regardless of the modulation mode. BE SURE that the student and instructor transmitters have identical trim settings and control motions. Verify by switching back and forth while moving the control sticks. Always remove the student transmitter's RF module (if it is a moduletype transmitter). When the TRAINER function is active, the snap roll function is deactivated. Other functions, such as IDLE-DOWN and THR-CUT, which have been assigned to the same switch, are not deactivated. Always double check your function assignments prior to utilizing the TRAINER function. When you select a different model, the TRAINER function is deactivated in the current model for safety reasons.

MIXES: the backbone of nearly every function Mixes are special programs within the radio that command one or more channels to act together with input from only one source, such as a stick, slider or knob. There are a variety of types of mixes. Types: Linear: Most mixes are linear. A 100% linear mix tells the slave servo to do exactly what the master servo is doing, using 100% of the slave channels range to do so. An example is FLAPERON to move exactly the same amount. A 50% linear mix would tell the slave servo, for example, to move to 50% of its range when the masters control is moved 100%. (see p. 52.) Offset: An OFFSET servo is moved a set percent of its range. An example of this is AIRBRAKE Curve: Curve mixes are mostly used in helicopters, but may also be used in airplanes and gliders. An example is THROTTLE-NEEDLE mixing, where the in-flight needles servo is moved, changing the mixture, as the throttle servo is moved. (see p. 65.) Delay: Delay mixes are part of a few very special functions that make the servo move to its desired range more slowly. THROTTLE DELAY (simulates turbine engines, p. 66) and the elevator delay in AIRBRAKE are two examples of this (see p. 62). DELAY in HELI (see p. 103) is another example that slows the servo movement to the trim settings for the other conditions.

Not displayed if master is not CH 1-4, because 5-9 have no trim. Ex: two rudder servos. With TRIM OFF, rudder trim would bind the two servos. TRIM ON resolves this. On/off choices: SWITCH: Any of the positions of any of the 8 switches may be used to activate a mix. Up&Cntr, Cntr&Dn options allow the mix to be ON in 2 of the 3 positions of a 3-position SWITCH. NULL: No SWITCH can turn this mix OFF. This mix is active at all times. LOGIC SW (Lsw1 to 3) may be assigned. Set up LOGIC SW: See p. 38.

Lastly, an electronic kill switch set to "off" prior to the aircraft's power being shut off adds an additional safety should someone accidentally turn on the mechanical kill switch on the exterior of the model. Bomb Drops, Paratroopers, and other Released Items: Many sport and scale models include one or more of these fun addons. Typically, all are controlled by a simple micro-switch plugged into CH9 or CH10. The switch is assigned in AUX-CH.
GLIDER MODEL FUNCTIONS Please note that nearly all of the BASIC menu functions are the same for airplane (ACRO setup), sailplane (GLID 1A+1F 2A+1F 2A+2F setups), and helicopter (HELI setups). The features that are identical refer back to the ACRO chapter. The glider BASIC menu includes MOTOR CUT and does not include IDLE-DOWN or THR-CUT. Note that in all cases where ACRO programming labels channel 3 as throttle, GLID programming labels channel 3 as ARB (airbrake), since airbrakes are normally operated on channel 3 in gliders. This includes STK-THR reading STK-ARB.

Important note: prior to setting up throttle hold, idle-ups, offsets, etc, be sure to get your normal condition operating properly. Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and having completed all range checks, etc, gradually apply throttle until the helicopter becomes light on the skids.

What is a gyro? A gyroscope is an electronic unit that senses motion and corrects for it. For example, if the wind blows
How does it help in helicopter setup? A good gyro will totally eliminate the need for revo. mixing. The gyro will sense and correct the unwanted motion for you, so you dont have to spend time to get a complex curve operating properly. Gyro sensor types: There are many different kinds of gyros. Early gyros were mechanical, with a spinning drum similar to a childs gyroscopic toy. The next generation utilized a special type of crystal, called piezoelectric, which sensed the System) technology. These sensors, or computer chips, sense the motion. MEMS is far more accurate and less susceptible to inaccuracies caused by temperature changes, etc. Types of gyro responses: Normal: sense motion and dampen it (if the gyro rotates off course for 2 seconds, it corrects for 2 seconds). until the same rotation is achieved. Stick priority: a feature on most high-end gyros. The more input given on the channel the gyro controls, the less sensitive the gain is automatically. This way, if you give a large input for a stall turn, for example, the gyro turns itself off and model straight. (If your gyro does not include stick priority, you can manually create it. Please see www.futaba-rc.com\ faq\.) Choosing the right gyro for your skills, your helicopter, and your budget: Mechanical: some are still available. They are very challenging to set up and not as reliable as piezo or SMM. Non-Heading-Hold Piezo: these are now inexpensive gyros that are reliable and easy to set up. Some have dual rates and Heading-Hold Piezo: Until recently, the cream of the crop. Expensive, and more complex to set up. Adds GPS-like Heading-Hold SMM: 21st Century gyro technology. Computer chip technology. Expensive, easier set up, higher using specialized digital servos. Examples: GY401: Simpler set up. Ideal for learning aerobatics through 3D. GY502: Better centering than 401 for more advanced aerobatics. Ideal through Class III competition. GY611: Exceptional center. Extremely fast response time. Requires specialized servo. Heading-Hold MEMS: GY520 is the smallest and lightest heading hold AVCS gyro available today. Its cutting-edge MEMS (Micro Electro Mechanical System) sensor design, ultra high-speed processing speed and advanced PID control algorithm put it a quantum leap ahead of all other heading hold gyros in size, weight and performance. The GY520 has been optimized to work with small electric models and larger nitro (.30 through.91) sized helicopters.
