How to correct your Lama from wagging it's tail.

Please make sure you are stand behind the helicopter. Also, when you adjust the "GAIN" switch on the 4-IN-1 Main board, please disconnect the battery from the helicopter first before making the adjustments.

If you adjust the "GAIN" Switch on the 4-IN-1 Main board to the right as the arrow shows in the above picture, the tail will move to the right as shown in the second picture above
If you adjust the "GAIN" Switch on the 4-IN-1 Main board to the left as the arrow shows in the above picture, the tail will move to left as shown in the second picture above

The GAIN switch will balance out LEFT / RIGHT movement, this may take time but once done you will have a stable tail. The GAIN position is of course dependant on the helicopter, and each helicopter may have a different perfect position.
