Notes: The modes in the table are only available for A3 Super 3/4, A3 Pro V2 and A3 Mini. The color of the LED shows the current mode of the gyro while in use.


When operating in GYRO OFF mode the gyro will be deactivated completely, and the airplane will be completely under the control of your transmitter as it was before installing the gyro. This mode is usually used for testing purpose only.


The NORMAL mode, also known as the 'Rate mode', is the most basic function of the gyro. It works based on the rotation rate control of each axis of the airplane. When operating in this mode, the gyro will only correct currently occurring rotational movements, a momentary reaction will be applied to the servos when the airplane rotating on corresponding axis, the servos will move back to their neutral position as soon as the airplane stops rotating. The NORMAL mode can be used with nearly any size and type of airplanes. It can effectively improve the stability and precision of the airplane and reduce the stall point specially.


The LOCK mode is also known as the 'Attitude Lock mode', '3D mode' or 'AVCS mode'. Different from NORMAL mode, the gyro will perform a permanent correction for rotational movements on each axis constantly. That is when you release the sticks the airplane will stop and lock its current position immediately. This mode is well suited for practicing basic 3D maneuvers such as hovering or knife edge. Since it can help you to lock the attitude of the airplane, it is also helpful for landing.


The ANGLE mode, also known as the 'Trainer mode' or 'Attitude mode', will limit the maximum angle of the airplane on both roll and pitch axes. Roll and loop are not allowed in this mode, the airplane will be stabilized all the time, independent of any stick input. This prevents the airplane from being tilted into a larger angle that may cause a danger. As soon as the sticks are released, the airplane will be brought back to horizontal position automatically. You can use this mode as emergency rescue, or in other applications, e.g., to have a training for new beginners or to use for FPV. The maximum allowed angle of this mode can be specified by user.


The LEVEL mode is also known as the 'Auto-Level mode', 'Auto-Balance mode' or 'Horizon mode'. When operating in this mode, the airplane will be brought to horizontal position automatically when releasing the sticks. Different from the ANGLE mode, there is no maximum angle limitation in this mode and the airplane will be stabilized only when there is no specific control input from aileron and elevator sticks. This mode can be used if the pilot becomes disoriented and would like to save the airplane from crashing.


The HOVER mode, also known as the 'Auto-Hover mode', provides the same functionality as the LEVEL mode. The only difference is that when you release the sticks, the airplane will be brought to vertical position (nose up) and keeps hovering. This mode is designed to help you to learn hovering maneuver and reduce the probability of crashing.
