Flight Mode

A3 Super II provides 6 different flight modes. You can assign your desired flight mode for each position of the 3-way switch using the config software or the programming card. If the input [MOD] is not connected, system will always default to the mode that has been assigned to Position-1.

Gyro Off Mode

Choose this mode to disable the gyros for all channels. The plane will be completely under the control of the radio. The plane will go back to its previous performance when operating it in this mode. Usually it is only used to test.

Normal Mode

Normal mode is the most basic application of the gyro. In this mode, the gyro will sense angular velocity on each axis and make a momentary reaction. The normal mode is suitable for all types of fixed-wings, it can effectively improve the stability of your plane specially on a windy day.

3D AVCS Mode

The AVCS mode is an advanced application of the gyro. By adding an integral algorithm to the gyros, the controller will try to lock the plane to its previous attitude if there is no command sent from the transmitter in a flight. This mode can effectively help you to accomplish such hard actions as hover and knife edge. But this mode is designed especially for the 3D planes, it's not suitable for the planes those not designed for 3D flight.

Auto-balance Mode

The auto-balance mode is designed for the new beginners or the FPV applications. When operating in this mode, the controller will command the plane to maintain level flight automatically when you release the sticks. When switch it to this mode from any other modes in an emergency, the plane will recover to the level flight automatically, which we call "one-click rescue".

Auto-hover Mode

The auto-hover mode is another form of the self balance ability of the controller. The only difference is that the correction from the gyro will be applied to both pitch and yaw axes, to keep the plane always vertical. When switch to this mode, the plane will lift its nose and start to hover automatically, which we call "one-click hover".

User Defined Mode

This mode allows you to select different mode for each axis, from normal , 3D or gyro off mode.

Stick Control Mode

Manual Mode(MM): When manual mode is chosen, the sticks are used to control the surfaces directly as usual. That is, there is no rotation rate or tilt angle locking and limitation when you move the sticks. All the servos will be completely under the control of the radio. It's more obvious to the users because you can see the servos move following the sticks as you expected. The plane will maintain its original control behavior when operating it in this mode.
Auto Mode(RR/AR): When using this mode, the controller will take over the control of all servos. The sticks are used to control the rotation rate (RR) on each axis when flying in normal or 3D mode, or the tilt angle rate (AR) on each axis when flying in auto-balance or auto-hover mode. The max rotation rate and max tilt angle can be set in the program card or the config software. In this mode, the controller will handle the position of the surfaces based on the actual rotation rate or tilt angle of the plane intelligently. This is why the movement of the servo will become different from the manual mode.

Flight Mode	Manual Mode	Auto Mode
Gyro Off	MM	MM
Normal	MM	RR
3D AVCS	MM	RR
Auto-balance	MM	AR
Auto-hover	MM	AR
User-defined	Depends on the flight mode of each axis

MM: Stick controls the servo directly.

RR: Stick controls the rotation rate on each axis.

AR: Stick controls the tilt angle rate on each axis.

NOTES Whatever the setting of control mode is, the stick is always used to control the servo directly when operating in gyro off mode or the gyro of the corresponding axis has been disabled.
