Basically what AttitudeControl does is leveling your helicopter by the flip of a switch or press of a button. There are different options on how the helicopter will be leveled which can be selected in PARAMETER MENU.

* Angular Mode<br />

:In this mode the helicopter flies like a quad copter. You have full control over pitch, but pushing aileron or elevator will only cause the helicopter to tilt by a given angle instead of rotating it around the roll or pitch axis. This makes flying much easier as you can't flip over the helicopter. Instead the maximum tilt is limited by your stick input. (Note: If you want to train inverted hovering using the angular mode, you will have to bring the helicopter into inverted position with AttitudeControl disabled first and then activate it).<br />

== Activating AttitudeControl in flight ==

== Activating AttitudeControl in flight == <!--T:8-->

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 sticks for aileron and elevator. Here the amount of deflection 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). So what you need on transmitter side as a switch that controls the AttitudeControl channel (which channel number this is you setup when doing the receiver and function assignments in RECEIVER MENU!). When the switch is in OFF Position the channel is moved into one direction, i.e. to -100% throw. Now when you flip the switch in order to activate the 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 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 want very quick and instand 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!<br />

'''As an alternative to using a separate channel for activating the AttitudeControl you can also the gyro gain channel, i.e. when you only have a 6-channel transmitter or when using a receiver with standard wiring (here we simply can't connect an additional channel physically).''' The activation of AttitudeControl will work quite similar as described above for the separate switch channel, moving the channel into one direction will activate the AttitudeControl and the amount of deflection of the channel determines the stabilization gain, when moving the gyro channel into the other direction the leveling is disabled. But additionaly here the gyro gain channel also still adjusts the gyro gain. Precisely this happens when the channel is moved in the direction where the leveling is disabled. Here the amount of deflection adjusts the gyro gain and sets the gyro into heading lock mode. So for example you would assign a switch to the gyro gain channel and adjust the throw into one direction to let's say -50% and in the other direction to +60%, resulting in a gyro gain of 50% and a stabilization gain of 60%. By flipping the switch you can activate/deactivate the AttitudeControl instead of toggling the tail gyro between "Normal-Rate" and "HeadingLock" mode. The gyro gain value of -50% will be saved internally when switching into positive direction.<br />

'''As a third alternative you can use the bank switching feasture and set the attitude gains fixed for each flight mode.''' In this case the AttitudeControl will be active as long as the flight mode is selected. So you could use one bank/flight mode for hovering and sports flying, one flight mode for 3D aerobatics and a third one with angular mode. Gain adjustments and parameter settings are all done in the StudioX software or StudioXm app and you can switch between modes using a simple 3-position switch. In this respect also note that you can even combine flightmodes with a separate rescue switch channel! So you could have one mode where AttitudeControl is always on, i.e. when using angular mode and then you have your other to flightmodes/banks for unstabilized flying but in which you can pull the rescue bailout at any time.<br />

{{WARNING_QUOTE|When using AttitudeControl with combined switch channel make sure AttitudeControl is at least deactivated once before take off. Otherwise the tail gyro gain would be minimal as the system would not have been able to determine your tail gain adjustment after initialization.<br />
