Was ist die Rettungsfunktion und wie verwendet man sie?

Im Prinzip ist die Rettungsfunktion (AttitudeControl) eine Lagestabilisierung, die den Heli auf Knopfdruck in die Schwebeposition bringt und dort hält. Dabei gibt es verschiedene Möglichkeiten, wie sich das im Detail auswirkt. Die Art der Stabilisierung lässt sich im PARAMETERMENÜ auswählen.

Bitte beachte, dass die Rettungsfunktion (AttitudeControl ) ein optionales Feature ist. Die zugehörigen Menüpunkte können nur ausgewählt und aktiviert werden, wenn die MICROBEAST ULTRA ProEdition Firmware auf dem Gerät installiert ist. Dieses optionale Update kann über den freakware Webshop gekauft und dann mit der StudioX App auf das Gerät aufgespielt werden.

Stabilisierungsmodi

• Quadmodus
  

In diesem Modus fliegt der Heli ähnlich wie ein Multicopter. Das Pitch kann "ganz normal" gesteuert werden, aber wenn man Roll oder Nick betätigt, dann wird der Heli nur um einen bestimmten Winkel gekippt, nicht hingegen mit einer bestimmten Geschwindigkeit gerollt. Das erleichtert das Helifliegen enorm, denn der Heli kann nicht in eine "schwierige Position" gebracht werden. Der maximale Kippwinkel wird durch den maximal möglichen Steuerknüppelausschlag begrenzt. (Hinweis: Wenn Du im Quadmodus auf dem Rücken schweben willst, dann musst Du die Stabilisierung ausschalten, den Heli umdrehen, und dann die Stabilisierung in Rückenlage wieder zuschalten).

• Rettungsmodus
  

Beim Zuschalten des Rettungsmodus wird der Heli zurück in die Schwebeposition gebracht, z.B. wenn Du die Orientierung verlierst. Dabei ist es völlig egal, wie der Heli gerade fliegt, senkrecht oder auf dem Rücken, er wird immer in die (einigermaßen) sichere horizontale Lage gebracht, so dass Du wieder die Kontrolle übernehmen kannst. Wenn Du Rettung mit Pitch verwendest, dann kontrolliert das System sogar das Pitch, so dass der Heli auch in vertikale Richtung mehr oder weniger stabil steht. Oder Du verwendest diese Funktion dazu, dass der Heli schnell an Höhe gewinnt, weit weg vom Boden. Es besteht zudem die Möglichkeit, einen Rettungsboost über die StudioX Software oder StudioXm App aktivieren, die einen zusätzlichen kurzen Pitchstoß gibt.

• 3D - Modus
  

Dieser Modus funktioniert fast genauso wie der Rettungsmodus, nur mit dem Unterschied, dass der Heli sowohl in Normallage wie auch in Rückenlage stabilisiert wird. Das System erkennt, welche Lage näher zu erreichen ist und hält den Heli dort, ohne ihn komplett umzudrehen. Das ist von Vorteil, wenn man (3D) Kunstflugmanöver üben will, z. B. Rückenflug, Überschläge oder TicTocs. Da man die AttitudeControl immer durch Steuerknüppeleingabe übersteuern kann, bietet sich sogar die Möglichkeit, die Funktion für einen längeren Zeitraum eingeschaltet zu lassen. So kann man z. B. einen Überschlag üben und sich vorerst nur auf das saubere Aussteuern von Pitch konzentrieren, während Nick und Roll nicht so präzise gesteuert werden müssen. Wenn der Heli über 90 Grad nach vorne gekippt wird, so wird die AttitudeControl den Heli weiter in Richtung Rückenlage ziehen und dort halten, ähnlich wie ein Fluglehrer oder Copilot. Zu beachten ist, dass der Heli im 3D - Modus nicht stabilisiert wird, solange er genau senkrecht steht! Durch dieses Feature fällt das Fliegen und Üben leichter, selbst wenn die AttitudeControl ständig zugeschaltet ist.

Neben der Wahl zwischen diesen fünf Modi (Quadmodus, Rettungsmodus, Rettung mit Pitch, 3D - Modus, 3D - Modus mit Pitch) bieten sich noch weitere Möglichkeiten, die AttitudeControl über die StudioX App an Deine Vorlieben anzupassen. So kann z. B. der Rettungsboost aktiviert werden, der den Heli für einen kurzen Moment in die Höhe steigen lässt, oder Du kannst den Pitchsteuerknüppel sperren lassen. Diese Optionen werden weiter unten im Detail erklärt. Außerdem bietet die Bankumschaltung (Flugphasenumschaltung) die Möglichkeit, während des Fluges zwischen unterschiedlichen AttitudeControl Modi und Einstellungen zu wechseln.

Adjustment at the device

If not already done, enter PARAMETER MENU by pushing the button briefly when the device is operational, so that the Menu LED next to point A starts to flash. Then repeatedly press the button to skip to Menu LED (menu point) L. At PARAMETER MENU point L you can choose between five different AttitudeControl operation modes. This is done by selection with the rudder stick. Tap the rudder stick repeatedly until the Status-LED lights in the desired color. 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). The assignment to the colors of the Status-LED is as follows:

Status-LED	AttitudeControl operation mode
off	AttitudeControl disabled
purple	Angular Mode
red flashing	Bail out rescue mode
red	Bail out rescue mode with pitch
blue flashing	3D - Mode
blue	3D - Mode with pitch

Briefly press the button store the setting. In case you've chosen a mode with collective pitch control, 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.

Only enable AttitudeControl when all initial settings in SETUP MENU and RECEIVER MENU have been performed. Otherwise the servos may drive to the mechanical full stop, start binding and may get damaged, e.g. when AttitudeControl gets activated when leaving the menu and the system starts to try moving the heli.

Hovering pitch

At PARAMETER MENU point M the collective pitch will move to the set hovering position. As described above this will be used 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.

By moving the rudder stick left or right you can descrease or increase the hovering pitch. The color of the Status-LED indicates the range where the pitch is in between at the moment. This range is specified as percentage of maximum positive/negative pitch.

Status-LED	AttitudeControl collective pitch
off	> 20% of maximum collective pitch
purple	> 30% of maximum collective pitch
red	> 50% of maximum collective pitch
blue	> 70% of maximum collective pitch

• 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 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.
• 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.

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.

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.
