==Fine tuning of AttitudeControl==

* The amount of deflection of the AttitudeControl switch channel controls the AttitudeControl gain. This determines the speed and roughness of the control input from AttitudeControl. If the effect of AttitudeControl is too low resp. the heli rotates back to horizontal position too slowly, increase the AttitudeControl gain by increasing the deflection of the AttitudeControl channel (i.e. by using the servo throw adjustment for this channel in the transmitter). If on the other hand the heli overshoots after reaching neutral position and bobs briefly, maybe the AttitudeControl gain is set too high. Reduce the gain accordingly. In such case also make sure that cyclic gain and cyclic feed forward are well adjusted. It is recommended to adapt the AttitudeControl gain to the preferred application. If you would like to use AttitudeControl as emergency rescue then set the gain as high as possible. On the other hand when using AttitudeControl mainly as a training aid, for example in 3D - mode, then make the effect of AttitudeControl rather weak, so that the system does take over control gently.

* In case 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. This is done in Quicktrim Menu at PARAMETER MENU point A or by changing the trim with the StudioX software or StudioXm app. When the positioning seems to vary randomly and the tilt gets a huge offset the longer you fly, this can be due to bad position measurement. The cause for this can be high frequent vibrations, fluctuations in temperature or misalignment of the device. On the other hand please note that minor deviations are inherent. When you feel the artifical horizon gets some little offset after some time let the heli stay in hover position for a few seconds without touching the sticks. Usually the horizon will recalibrate automatically then (as long as the vibration level is not too high).

Briefly press the button store the setting. In case you've chosen a mode with (collective) pitch control, briefly pressing the button at point L will lead to menu point M. Otherwise menu point M will be skipped und the system will exit PARAMETER MENU.<br />

<br />

<br />

At PARAMETER MENU point M the collective pitch will move to the set hovering position. As described above this will be used when the system rotates the heli and to keep the heli in hovering position (when using an AttitudeControl mode with pitch). Ideally the pitch angle is exactly as large as it is necessary to maintain a stationary hovering flight without ascending or descending. Typically this is somewhere in the range between 5 and 6 degrees.<br >

{{WARNING_QUOTE|If the maximum positive/negative pitch is changed at SETUP MENU point K in consequence also the hovering pitch will change! So after adjusting the maximum pitch also check and readjust the hovering pitch here at menu point M.

[[File:Warning.png|18px|sub]] When using the "3D - Mode with pitch" make sure that the maximum pitch range is symmetrical, i.e. the maximum positive and negative pitch are of same size. Otherwise the hovering pitch will differ in normal and inverted flight as the AttitudeControl pitch is calculated from each maximum pitch setting! The setting affects both directions, separate adjustment of the hovering pitch angles is not provided.}}<br />
