Stick Centering
A3-L will perform a stick centering automatically every time it starts, so a manual centering is no longer needed.
You just need to keep all the sticks ( except for the throttle) in their middle position before power on the controller,
and don’t move them while initializing.
If the servos drift to one side slowly when switching to 3D mode, you can
easily perform a centering by fast toggling the mode switch twice within 1 sec, it has the same effect as if you restart it.
Gain Adjustment
There are 2 knobs on the gyro (GAIN1 and GAIN2), they are used to adjust the gyro gain for each flight mode separately.
Clockwise for increase, anticlockwise for decrease. The gain is affected by many factors there is no standard answer to
that how much it should be. You need to fine-tune to get the best result during flights. We suggest you always start
with a lower volume for the first flight and then increase it gradually.
The normal gain (Basic Gain) (GAIN1) will take
effect in all flight modes, it’s the most basic feature of the gyro, don’t turn it to 0% anyway.
Remote Master Gain
The GAIN is used to control the master gain remotely. You can make a linear adjustment by using a knob or slider on
your transmitter, or make a 3-level gain control using a 3-way switch. The master gain is just an optional channel that
the gyro can still work properly without connecting this channel.
Device Reset
Press and hold the button while power on the gyro, you will see both Blue and Red LED turn on. Keep holding the
button for more than 4 seconds and don’t release it until you see the LED flashes Blue & Red twice, which indicates
that all the settings have been restored to the factory default.
