{{QUOTE|Bitte beachten Sie, dass AttitudeControl ein optionales Feature ist. Die nachfolgend beschriebenen Funktionen stehen nur zur Verfügung, wenn auf dem MICROBEAST PLUS die ProEdition Firmware installiert ist.}}

Wenn sich der Status der AttitudeControl länger als 8 Sekunden nicht ändert, wechselt die Anzeige zurück zur Anzeige des Heckkreiselmodus und die Status LED leuchtet blau oder violett.

'''Hinweis für Firmware Versionen vor 4.1.x: '''Sobald die AttitudeControl bei [[Manuals:MB_Plus:Parametermenu_L/de|Parametermenü Einstellpunkt '''L''']] aktiviert wurde, kann der Heckkreisel nicht mehr im Normal-Modus betrieben werden. Wird die AttitudeControl mit separatem Schaltkanal betrieben (siehe oben), dann steuert der Kanal für die Heckkreisel-Empfindlichkeit in beide Richtungen den Heckkreisel im HeadingLock-Modus an. Das Vorzeichen des Steuerausschlags ist hier nicht mehr relevant, nur die Größe des Steuerausschlags. Wenn Sie den Heckkreisel im Normal-Modus betreiben möchten, dann kann AtttitudeControl nicht verwendet werden und sie muss unter [[Manuals:MB_Plus:Parametermenu_L/de|Parametermenü Einstellpunkt '''L''']] deaktiviert werden (Status LED aus).}}

{{QUOTE|When using an AttitudeControl mode with collective pitch control (see [[Manuals:MB_Plus:Parametermenu_L|Parameter menu point '''L''']]) additional to the cyclic movement also the collective pitch is moved in positive or negative direction when AttitudeControl is activated and the helicopter approaches the horizontal position. The pilot can add collective pitch in the same direction by using the thrust stick, but not in the opposite direction. Check to see if this works correctly and whether the control directions are correct. If the helicopter is kept in hovering position, some positive collective pitch must be applied by AttitudeControl and you can use the thrust stick to add more positive pitch, but not less. Analogous this must work when the heli is in inverted hovering position if using the „3D - Mode with collective pitch control“. Here AttitudeControl will apply some negative collective pitch and you can only add more negative pitch, but not positive.}}

===Flying with AttitudeControl===

If not done already, for the first flight keep AttitudeControl deactivated and adjust all flight parameters like tail gyro gain, cyclic gain and so on as described under [[Manuals:MB_Plus:Flying|Flying and optimization]].<br />

If the heli is setup well you can familiarize yourself with the effect of AttitudeControl. For this we suggest to use the „Bail out rescue mode“ (see [[Manuals:MB_Plus:Parametermenu_L|Parameter menu point '''L''']]). Fly the helicopter in a sufficient amount of height in a stable hover and activate the AttitudeControl by using the appropriate switch. The helicopter should continue to hover in approximately the same position. Now give some aileron or elevator stick input and release the stick when the helicopter reached some oblique position. AttitudeControl should bring the helicopter back to the horizontal position more or less rapidly.<br />

Deactivate AttitudeControl and again tilt the helicopter by giving some stick input. Now the helicopter will stay tilted if you release the stick. Only when AttitudeControl is activated by flipping the switch again, the helicopter will be rotated back to horizontal position as before.<br />

{{WARNING_QUOTE|If using an AttitudeControl operation mode with collective pitch control (see [[Manuals:MB_Plus:Parametermenu_L|Parameter menu point '''L''']]), moving the thrust stick does not have any effect in some area as AttitudeControl takes over collective pitch control as long as the thrust stick is in this area and AttitudeControl is activated. Therefore make sure the thrust stick is in a position that will roughly produce the same amount of collective pitch, before and while deactivating AttitudeControl. Otherwise when deactivating AttitudeControl the helicopter would make a leap down, if the thrust stick controls a smaller pitch angle than AttitudeControl.<br />

[[File:Warning.png|sub|18px]]For safety reason you should never take off or land with activated AttitudeControl. As AttitudeControl actively gives control commands to the control loop of MICROBEAST PLUS, the swashplate may tilt to one side if the helicopter is not placed perfectly level on the ground. This  may cause the helicopter to tilt and crash when trying to take off or when the motor is switched off and the main rotor is running out.}}<br />

'''Fine tuning of AttitudeControl'''<br />

* 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 (dial1) and cyclic feed forward (dial 2) 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.

* 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. This is done at [[Manuals:MB_Plus:Parametermenu_A|Parameter menu point '''A''']].
