SETUP MENU G - Collective and cyclic pitch mixing (CCPM)
At SETUP MENU point G you have to choose the electronic mixing type for the swashplate servos or select “no mixing“ for switching off the mixing in case your helicopter has a mechanical swashplate mixer. For the electronic mixer you can choose one of the presets for 90°, 120° and 135°/140° swashplates that are suitable for most helicopters on the market (which kind of CCPM your helicopter uses can be read in the manual for your helicopter). When you're using a multiblade rotorhead that requires to adjust the swash phasing electronically this can be done with the StudioX/StudioXm. Apart from that you can set nearly any other kind of swash mixing and swash geometry with StudioX if required.
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 MICROBEAST PLUS!
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) |
| off | user defined |
Setup with StudioX
Choose the swashplate mixing/swash type of your helicopter by clicking the corresponding button in the software.
To change the swash phasing or set a different type of swash mixing click Customize. Then a screen with advanced setup options will open.
Virtual swash rotation
To change swash phasing for multiblade helicopters adjust the Virtual swash rotation (the phasing is set independent from the actual swash mixing type, so make sure the correct swash type was chosen before!). 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
You can change the Swash geometry just as you like. You will see that the values you see here are preset by the type you've chosen in the SETUP MENU overview. 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 can not change the servo throw in the transmitter as with the transmitter you do not directly control the servos with the radio!).
Setup with StudioXm
Choose the swashplate mixing/swash type of your helicopter by clicking the corresponding button in the app.

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.
