GYA553 is a light programmable 6-axis stabilization system (integrated 3-axis MEMS gyroscopic sensor + 3-axis accelerometer) for control and stabilization of aircraft models powered by internal combustion engine and electric motor with the possibility of remote gain control in 3 axes and switching operating modes using a transmitter. It allows setting a number of parameters with the help of buttons and LEDs on the gyro or with the help of the GPB-1 programmer (with the latest firmware version). It connects to the receiver via the S.BUS2 port; in addition to PWM outputs for classic servos, it also offers an S.BUS output port with up to 18 channels. The GYA553 supports ailerons, elevator or rudder controlled by a pair of servos and offers mixes for gliders and butterfly tail surfaces. Gyro activity is indicated by an LED indicator.
Three operating modes (switched by remote gain control: signal -130% ~ -50% Normal mode, -50% ~ + 50% gyro off, + 50% ~ + 130% AVCS mode)
Both stabilization modes can have their advantages in different flight modes and piloting styles; thanks to the possibility of remote switching, you have the option of selecting the optimal operating mode with the optimal gain value individually for each flight mode.
Rescue mode (activated by a switch in a special channel)
When the GYA553 rescue mode switch is turned on, it puts the model into level flight. Thanks to this, it is possible to get out of a dangerous situation if, for example, you lose track of the orientation of the model in space. Rescue, of course, has its limits given by the laws of physics - for example, when dragged at a low height above the ground will almost certainly not help.
Remote profit control
Using the three channels of the RC remote gain control kit, the gyro gain can be adjusted with the help of a transmitter independently in all three axes. You can have the optimal gyro operating mode programmed on the transmitter for each model flight mode with the optimal gain value for each axis.

Connection to the receiver
The gyro is connected to the S.BUS2 serial output of the receiver with a single cable. At least a 10-channel RC kit is required to take full advantage of the GYA553's capabilities. Gyro is equipped with PWM channel outputs enabling the connection of classic servos (2x ailerons, 2x elevator, 2x rudder - mirror-mounted installation of paired servos in the model is assumed), while the output for rudder 2 has an optional function - either PWM output for rudder 2 or serial S .BUS output with up to 18 channels (according to RC kit) enabling connection of S.BUS / S.BUS2 servos for channel controlled channels and for all others.
Gyro can work with analog and digital servos (for 4.8 V and HV power supply up to 8.4 V). The servo type is selected programmatically (for digital servos the output signal has a repetition frequency of 285 Hz, for analogue 70 Hz).
If a new version is available, the GYA553 firmware can be updated via the Futaba CIU-3 or CIU-2 USB interface.
The gyro set contains: gyro GYA553, double-sided foam adhesive tape for fixing the gyro, connecting cable, operating instructions.
