Flight Mode
A3L Supports 3 flight modes, you can switch between them using a 3-way switch on the transmitter. But if you are using a 2-way switch instead then you can only use 2 of them during flight. The color of the LED shows you that the flight mode currently selected, as shown below.
Flight Mode Switch Position Color of LED Description
1 Normal Mode POS-1 Blue Gyro rate mode
2 Gyro Off Mode POS-2 (Middle)) Off Gyro deactivated mode
3 3D AVCS Mode POS-3 Red AVCS Mode designed for 3D flight


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.


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.


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.
