Do not turn the sensitivity trimmer with too much force. The trimmer may break. Always use the miniature screwdriver supplied to make adjustments. Make positive maintenance of the fuselage tail section a habit. The rigidity of the tail section has a large effect on gyro performance. Therefore, loose supporter and tail pipe aging also have a large effect on the characteristics.
Service the fuselage with a little vibration as possible. Fuselage vibration has a very adverse effect on gyro performance. 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. 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. When using the gyro with a helicopter, install the GY at least 10cm from the drive motor. The drive motor generates strong electromagnetic noise.
This noise may interfere with the gyro sensor and cause erroneous operation. Mount the GY so that metals or other conductive objects do not touch the gyro case. The GY uses a conductive resin case to reduce electromagnetic interference. Because the surface of the case is conductive, metal objects may cause a short circuit. If a connector works loose due to vibration during flight, control may be lost and result in a dangerous situation.
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.
Operation Precautions Never move the fuselage for about 3 sec- onds after turning on the gyro power shared with receiver. 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. 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. Symbol: ; Prohibited ; Mandatory 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 turning on the power, set the transmitter switch to the AVCS position and turn on the transmitter power switch, then turn on the gyro power. Do not operate the rudder trimmer while flying in the AVCS mode. When the power is turned on, the GY assumes that the rudder stick is in the neutral position. If the rudder trimmer is moved during flight, the neutral position will change. 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. Therefore, if rudder mixing is ON, the model will operate the same as if the neutral position changed.
The gyro con- stantly compares the transmitter rudder operation signals and gyro internal reference signal transmitter rudder neutral signal and controls the helicop- ter tail rotation speed accordingly. Therefore, for the AVCS function to operate normally, the rudder neutral signal must be memorized in the gyro before flight. The gyro is normally used in this state.
The monitor LED flashes instantaneously and the rudder signal is memorized. If the trimmer was moved during flight, the memorized neutral position can be updated to the current neutral position by repeating this operation.
When performing this operation, land the model and hold the rudder stick in the neutral position. When you want to check the servo neutral position during linkage neutral check, etc. This operation returns the rudder servo to the neutral position. The gyro judges that an angular velocity com- mand was received and rotates the tail, therefore, the neutral position changes.
The model flies in the same rudder trim position including sub trim as when the power was turned on neutral position memorized in the gyro. When flying in the AVCS mode, set the rudder trim to the same position under all flight conditions, including hovering and idle up. In the AVCS mode, the gyro automatically trims the rudder so that trimming during flight and other precision rudder trim adjustments are unnecessary.
This mode is for use with Futaba digital servos only. When using servos that are not compatible with high-speed pulse drive, other than digital servos, never set the DS switch to ON. The servo may be destroyed.
Miniature trimmers and switches are used with the GY to reduce its size. When operating the trimmers and switches, always use the miniature screwdriver supplied and do not apply excessive force. However, this is because the gyro sensitivity is set to a high value and is normal. When the sensitivity is too low, length the servo horn. Conversely, when hunting does not stop, shorten the servo horn.
FUTABA GY401 Using
While this how to article will be specifically for the Futaba GY gyro, similar principals can be applied to almost any heading hold RC helicopter tail gyro. By the way, if you have a GY gyro, you can read the GY setup article here. Or if you need the manual for the GY Also, it would be a good idea to check that your ball links are on snug, but not too tight and can move freely. Then plug the other lead red servo plug — yellow wire into the gain channel in your receiver.

For instance, do not fly the model and result in a dangerous situation. Let the model stand for about 10 minutes to drive motor.
