The first menu point of the PARAMETER MENU gives you the possibility to quickly adjust swashplate and rudder trim on the flying field. This may be neccessary when your helicopter slowly drifts in hovering flight or when it doesn’t climb out straight on sudden collective pitch inputs. Additionaly when using the AttitudeControl feature (only included in PROEDITION firmware upgrade) you may trim the reference point of the artificial horizon in case the heli does not level perfectly when AttitudeControl stabilization is active.<br />

For the Quick Trim adjustment you have to enter PARAMETER MENU point A. To do so briefly push the button when in operation mode, so that the yellow Menu LED next to A will start flashing quickly (do not hold the button too long, as this will enter SETUP MENU point A which is shown by a solid lit up LED A).<br />

To activate the swashplate trimming mode make sure your tail gyro is set to Heading Lock mode and that AttitudeControl is not active at the moment (if applicable)! Then you can to directly adjust aileron, elevator and collective here, 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 tapping the aileron or elevator stick briefly in the desired direction. To trim the collective we use the rudder stick (left = minus, right = plus). 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 and when the trim has changed the Status LED will flash for a moment.<br />

==Rudder servo== <!--T:5-->
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 />

You can delete all trimming by pushing and holding the button on the device for at least 10 seconds, then release. This will reset all trims back to factory state but will NOT affect the single servo trimmings of SETUP MENU! So you can change the trimming on the flying field if necessary and if it was wrong or too much, you can easily clear it out without affecting the other settings.<br />

==Trimming the artificial horizon (optional)== <!--T:7-->
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''' with the transmitter‘s AttitudeControl channel and make sure the tail gyro is in Heading Lock mode. 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 color of the Status-LED gives you an approximate indication of how much you did trim and when the trim has changed the Status LED will flash for a moment.<br />
