There is one exception: The rudder servo can be trimmed on the remote control when the tail gyro is operated in Normal-Rate mode. Note, however, that this trimming should only be temporary as MICROBEAST PLUS calibrates the stick center positions during every initialization process. Thus, on the next flight the servo would be back on center position despite trimming in the transmitter.}}<br />

===Swashplate servos=== <!--T:2-->
Contrary to centering every single servo at Setup menu point G, here you are able to directly adjust aileron and elevator without taking care about the single servos. Similar to the digital trim function of most transmitters here at Parameter menu point A you can adjust the swashplate “one click“ by shortly moving the aileron or elevator stick in the desired direction. If you want to trim the swashplate any further repeat tapping the stick several times or simply hold the control stick pushed for a longer time to automatically perform several trim steps. The color of the Status-LED gives you an approximate indication of how much you did trim.<br />

===Rudder servo=== <!--T:3-->
If the tail gyro is operated in Normal-Rate mode, the rudder servo must often be trimmed precisely so that the tail rotor produces just enough thrust to counteract the rotor torque in hovering flight. Otherwise the helicopter would constantly drift into one or another direction on its vertical axis as the gyro only dampens sudden movements but does not control the tail rotor‘s absolute position.<br />

* If the tail gyro solely is operated in HeadingLock mode, trimming the rudder servo is not required under normal circumstances. Here the gyro actively controls the rate of rotation whereby drifting is excluded on the vertical axis. Anyhow, in unfavorable mechanical conditions it may be helpful to fly the heli in Normal-Rate mode once and to trim the rudder servo accordingly, so that the mechanical throw is balanced more equally.}}<br />

===Reset adjustment=== <!--T:4-->
During the trim procedure you can delete the just performed trimming by moving the rudder stick in any direction. All servos will be moved to the initial position from entering Parameter menu point A. Note that a subsequent reset to previous states is not possible! If the servo trimming was changed and Parameter menu point A is left, the servo positions will be saved permanently. You can only bring back the servos to the previos positions by manually trimming them back into the opposite direction.<br />

===Trimming the artificial horizon (optional)===
===Trimming the artificial horizon (optional)=== <!--T:5-->
If the helicopter is not aligned horizontally as desired with active AttitudeControl, i.e drifts to one side in hovering, the artificial horizon can be readjusted. To do so, activate AttitudeControl at Parameter menu point '''A''' via the transmitter‘s AttitudeControl channel to switch from trimming of the servos to trimming of the horizon. The Status-LED will flash indicating that AttitudeControl is on (if the Status-LED is lit permanently, you are in servo trimm mode as described above). By moving the aileron or elevator stick the roll and pitch tilt of the horizon can be increased/decreased. Briefly touching the appropriate stick will trim the horizon stepwise by 0.5 degrees to the specific direction. Touching the stick repeatedly or holding it for longer time will trim the horizon by several steps. The Status-LED indicates the trim values: when it lights in blue color both angles are 0 degrees resp. they are in the factory setting. If the Status-LED lights red, one or both angles are adjusted slightly. If the Status-LED is purple then one axis is trimmed by more than 5.0 degrees. When the Status LED goes out, one of the two axes is further trimmed than 10.0 degrees, which is the limit for each axis! By moving the rudder stick you can remove the trimm that has been set since entering this menu point.<br />
