GY520 Link
Description of the function of each parameter
• ID
Displays the gyro serial No. It cannot be changed.
• Channel
Initial value: Rudder=2, Gain=3
Specifies the rudder channel and gain channel numbers connected to the receiver. It
is effective at S-Bus connection.
• Flight Mode
Initial value: F3C
Sets the F3C and 3D operation modes. When the setting is changed, the parameters
needed to operate the gyro are automatically initialized.
• Servo Mode
Initial value: Digital (1520)
Selects the servo type. When the setting is changed, the parameters needed to
operate the gyro are automatically initialized.

• Gyro Reverse
Initial value: Normal
Sets the gyro operating direction.
• Mounting Surface
Initial: Upper side
Inputs the gyro mounting direction. The rudder left and right operating directions are
unambiguously determined by this parameter and the gyro reverse parameter.
• Response Setting
Mode
Initial value: Standard
Selects the rudder response speed. Changing this parameter changes the rudder
operation feeling and rebound characteristic at tail stopping and the tail holding
characteristic. In the "Fast" mode, tail operation is most sensitive and the tail holding
characteristic becomes maximum. However, the rebound when the tail stops also
tends to become large. Select the mode matched to the characteristics of the tail. The
"Control Response" and "AVCS Response" parameters described below allow more
delicate response setting.
