SETUPMENÜ G - Taumelscheibenmischung
Bei Einstellpunkt G ist die für den verwendeten Helikopter notwendige Art der Taumelscheibenmischung auszuwählen. Hier stehen vordefinierte Mischer für Taumelscheiben mit 90°-, 120°- und 135°/140°- Anlenkung zur Verfügung. Natürlich lässt sich die Mischung auch deaktivieren, falls der Helikopter über eine mechanische Servomischung verfügt. Zusätzlich lässt sich über der StudioX Software eine beliebig definierbare Mischung realisieren. Für Helikopter mit Mehrblattkopf bzw. Scalehelikopter kann des weiteren die oftmals benötigte virtuelle Taumelscheibendrehung eingestellt werden. Welche Art der Taumelscheibenmischung Dein Modell benötigt, steht in der Anleitung des Modells.
Never set any kind of swash mixing in your transmitter even when electronic mixing is required! Deactivate the swashplate mixing in your transmitter or set it to mechanical mixing (which is often called “normal“, “H1“ or ”1 servo“ mixing), so that each stick function only moves one receiver output channel. The swashplate mixing is all done by the AR7210BX unit!
Adjustment on the device
The color and state of the Status-LED shows the currently selected mixing type. To select the desired type tap the rudder stick repeatedly in one direction until the Status-LED lights in the correct color:
| Status-LED | Swashplate mixer |
|---|---|
| purple | mechanical |
| red flashing | 90° (3 or 4 servos) |
| red | 120° |
| blue flashing | 140° |
| blue | 135°/140°(1:1) |
Setup with StudioXm
Choose the swashplate mixing/swash type of your helicopter by clicking the corresponding button in the app.

Virtual swash rotation
With the buttons + and - you can adjust the Virtual swash rotation/swashplate phasing if necessary (i.e. when using a scale helicopter with multiblade rotorhead). You can turn the swashplate internally by +- 179 degrees. To find out the exact value that is necessary for your helicopter align one rotorblade in parallel to the tail boom/longitudinal axis of the helicopter. Now when you move the elevator the rotorblade mustn't move at all. If it does, increase/decrease the phasing just until the blade is standing still. It must only react to roll or collective inputs similar as this would be the case with a two bladed rotorhead! The direction (sign) of phasing determines the control direction. If you have tuned the phasing into the wrong direction your control will be inverted, i.e. elevator will move the blades into the wrong direction when aligned 90 degrees to the boom.
Custom swash mixing
To create an individual swash geometry in case the given presets do not fit to your helicopter's swash type choose Customize. In example what you may do here is, when having a mechanical mixed helicopter, you can change the servo throw ratio of the aileron and elevator servo (outputs CH1 and CH2) in case these are not making similar cyclic pitch deflection (Note: You mustn't change the servo throw in the transmitter as with the transmitter you do not directly control the servos!)
By default the values you see here are preset by the type you've chosen in the overview before. Change them as necessary.
Additional info: What swash mixing is required for my helicopter?
Today most helicopters use a 120° swashplate, i.e. all ALIGN T-Rex helicopters as well as SAB Goblin, Mikado Logo, MSH Protos and many more. Mechanical mixing was very common on Thunder Tiger Raptor helicopters and Vario scale or trainer machines but is getting rare today. The type 135°/140° (1:1) is the most common type of "140° degrees" swashplates. Often it is also considered as 135° swashplate! There is no uniform designation for this type of swash mixing. The main idea with this type of swashplate is to have an equal servo ratio on the elevator axis, which will remove the collective interaction due to unequal servo movement and in consequence will give a extremely precise control of the heli. If this is the case on your helicopter (elevator and aileron servos are moving the same distance when steering elevator) then choose this type, no matter whether it‘s called 135° or 140° swashplate. You can find this type of swashplate for example on Shape, JR and Hirobo helicopters.
