Setup with StudioX app

When StudioX/StudioXm has connected to your MICROBEAST ULTRA, in the device overview main screen click the "Parameter setup" button. Then click the "Next" button repeatedly until you reach the screen "Bank 1 - AttitudeControl" or directly go to this options screen using the box on top. Here you can choose between five different AttitudeControl operation modes. If one of the AttitudeControl operation modes is selected, the AttitudeControl function is enabled and it can be activated/deactivated in operation by using the previously assigned transmitter channel for AttitudeControl. The "AttitudeControl disabled" option specifies the AttitudeControl is completely disabled and actuating the AttitudeControl channel has no effect (in terms of the AttitudeControl).


Hovering pitch

When an AttitudeControl mode with pitch is used, you can set the minimum amount of pitch deflection that is used to keep the heli in hovering position. 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. The value you see here is the percentage of the maximum amount of pitch. So if you've set up your helicopter with 12 degrees of pitch, you will roughly see 6 degrees of hovering pitch at a value of 50. If you like to measure the exact pitch click the "Measure" button. This will move the swashplate into hovering position temporarily.

• Please note that during operation you can always add more pitch by giving thrust stick input. The pitch you adjust here is only the minimum amount of pitch. So practically in case this is not enough pitch to keep the heli in the air you will always have the option to override the pitch input for safety reason.
• 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.
• If the maximum positive/negative pitch is changed at SETUP MENU point L in consequence also the hovering pitch will change! So after adjusting the maximum pitch check and readjust the hovering pitch here at menu point M.
• When tilting the helicopter the amount of pitch will change and you may not see the set amount of hovering pitch. This is because the system uses an internal algorithm that controls the pitch during rotation, trying to roll the helicopter with as less horizontal and vertical movement as possible. Anyhow, this algorithm bases on the assumption that you've set the hovering pitch as good as possible. But, for examply, when you've set more pitch in order to achieve the helicopter gaining height when AttitudeControl is active, this may not cause the helicopter to turn on spot properly.

Pitch boost

The option "Pitch boost" allows to set an additional pitch input which can be added for a restricted amount of time. For example when you set the "Pitch boost" to 80 and the "Boost time" to 1000, the system will give 80% pitch input for 1 seconds (=1000 milliseconds) as soon as the helicopter reaches horizontal position when activating the AttitudeControl. So you can use this to gain height instantly and get away from the ground, i.e. when rescuing the helicopter.

• You can use the "Pitch boost" feature in any of the five AttitudeControl modes, not only in the modes with pitch! On the other hand, when using "Pitch boost" in combination with Rescue with pitch or 3D-Mode with Pitch, first the system will use the "Pitch boost" for the given amount of time and then move the pitch to the given amount of hovering pitch.
• When the "Boost time" is set to 0 the "Pitch boost" is disabled resp. will not have any effect.
