Please note that AttitudeControl is an optional feature. It is only available on devices with MICROBEAST ULTRA '''ProEdition''' firmware installed. You can buy this optional update from the [https://www.freakware.de/en/beastx/software-updates-w19629 freakware Webshop] and flash the ProEdition firmware to your device with the StudioX app.<br />

= Activating AttitudeControl in flight =

== Separate channel ==

'''Usually we use a separate free channel on the transmitter to activate/deactivate the AttitudeControl during operation.''' When this channel is moved into one direction, the AttitudeControl is off, when you switch it into the other direction the AttitudeControl will be activated and your helicopter will be leveled when you release the aileron and elevator stick(s). The amount of deflection of the switch channel determines how strong the system reacts and how hard it tries to keep the helicopter in level position (and in consequence how hard it is to control the heli against).<br />

So what you need on transmitter side is a switch that controls the Attitude channel (the channel number is setup when doing the function assignments in RECEIVER MENU!).

* In "OFF"-Position the channel is moved into one direction, i.e. to -100% throw

* When you flip the switch in order to activate AttitudeControl, the channel is moved into the other direction, i.e. to +50%. In this case the AttitudeControl will activate with a gain of 50%.

* The LED display on the MICROBEAST ULTRA shows if AttitudeControl is active and how high the gain is. When the switch channel is moved into the OFF direction the Menu-LED A will light up and flash. In this case AttitudeControl is deactivated. When activating AttitudeControl and the throw of the channel is 100%, the LED N will light up. Adjust the deflection of this channel, i.e. by reducing the servo throw in the transmitter, so that the Menu-LEDs lights up next to point G lights up (usually at 50% as described above).<br />

= Fine tuning =

* The amount of gain/channel deflection must be tuned to your liking later when flying, 50 is usually a good starting point. If you don't want so hard reaction of the system, i.e. when you want to fly while the 3D mode is active for a longer time, you will lower the gain to maybe 30. If you need a very quick and instant turn around, you may raise the value to 60. Just don't go too high from the beginning as this can cause a very hard and abrupt reaction of the system, maybe harder than your helicopter likes!

* 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).<br />
