As was said before you need to calibrate (tell the unit where the horizon is relative to your CG). There should be a way to do it electrically or you can tip the sensor slightly in the same direction that the heli drifts. Bear in mind this will always change based on wind direction and the IR signal that varies from place to place. That is why most people will ball park it by tipping the sensor and then maybe electrically calibrate it and finally use the trims from time to time to achieve perfection. Perfection can only be achieved if the tail is not rotated. If the tail is rotated 180 for instance then the offset, calibration, or tuning is now the opposite that it needs to be, hence the use of trimmers.
If you calibrate (electrically) in an open field on a dead calm day once, your right / left, fore / aft trimming will be to a minimum. Otherwise you will be injecting an offset for the conditions of the day that may double the error when the conditions change.
