Multiplex Profi Tx Manual page 5

The Profi includes 2 defined mixers which are non-editable, an aileron differential mixer and
aileron-rudder combi mixer. These are always available and are setup by entering the Mixer
settings menu (GHI2)
The aileron differential mixer is used to set the aileron differential to reduce adverse yaw and/or
fine tuning the roll control on an aerobatic model to give a more axial roll. There are 3 settings for
the differential mix, ON, OFF and SPOILER+, the last option is used when you have ailerons raised
as spoilers (or in crow braking), in this mode the differential is suppressed when the ailerons are
raised so that the down going aileron has full movement for better roll control with the
spoilerons deployed. Note the differential can be set for individual flight phases and differential
can be + ve or –ve, this will depend on the model and the aileron servo set up.
The aileron-rudder mix is found under the Combi-Switch tab and this is used to mix some rudder
in when you move the aileron stick, useful for countering adverse yaw and balancing the turns
without having to move the rudder control. As for the aileron differential mixer, the mix %age can
be set for individual flight phases. Also the mix is switchable and a switch for this can be assigned
in the switch assignment tab in the Setup menu (ABC1), the switch can also be used for another
function if you wish, i.e. tow release on a glider so the aileron-rudder mix is off under tow but
becomes active once the tow release is activated. If no switch is assigned the mix is on when a
%age value is added.
