51 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 rota-
tion/swashplate phasing if necessary (i.e. when using a scale helicopter with multiblade
rotorhead). To set a different type of swash mixing click Advanced view. Then a screen
with advanced setup options will open.

51.1 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.
51.2 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!)
