ned switch this type of mixer delivers a constant signal only.
Preceding mixers (“
” symbol) and / or the trim (“Tr” of sticks 1 … 4) are included when the mixer input is set in
the “Type” column. Search for appropriate symbol “ ”, “Tr” or “Tr ” using the rotary control. Optionally all mixers
can be assigned a switch.
Setting of mixer inputs and directions for linear mixers:
Change screen page in the “Setting” column with a brief press on the rotary control. Select
ASY or SYM and set
desired mixer input between 0 and +/-150% using the rotary control. For asymmetrical setting, select page using
the input transmitter control (vertical line in the graph) and for switched channel “S” with associated switch.
Setting of non-linear mixer curves for curve mixers 9 … 12:
Between the two end-points “L” (Low) and “H” (High) up to six additional curve points can be defi ned. Basic notes
on operation can be found in the description of the »
Channel 1 curve « menu on pages 90 / 92.
Shifting the offset point (mixer neutral point):
Use the transmitter control to move the bar in the graph to the desired position, select
STO and press the rotary
control briefl y. The offset point is returned to the centre position using the bottom CLR function.
Notes:
DUAL RATE may limit the movement range of the vertical line. Mixers may also have been suppressed in the
»
MIX active in phase « menu.
• • MIX active/phase The mixers 1 … 12 can be disabled separately for each fl ight phase. In the » Free mixers « menu they are then
suppressed separately for each fl ight phase.

• • MIX-only channel This function is used to separate the link between transmitter controls 1 … 12 and the associated servo, i. e. the
transmitter control only continues to affect the relevant channel as a mixer input. In this case the de-coupled servo
is only accessible via mixers. 142
• • Dual mixer Four mixers designed for coupling two channels in such a way that they work in the same and opposed directions.
Example: differential rudder travel on a V-tail. In this case “
EL ” is defi ned as the “same-direction” function,
and “ RU ” as the “opposite” function. In this case it is essential to enter “normal” under Tail type in the » Model
type « menu!

• Swashplate mixer Mixer inputs for collective pitch, roll and pitch-axis can be set individually (-100% … +100%), except for helicop-
ters with one servo for collective pitch control.
CLEAR resets altered values to the default of +61%.
Note:
Ensure that servos are not mechanically obstructed or stalled if you set large values at this point.
