Note:
Except for the “1 Servo” choice, swashplate mixer
proportions must also be set in the »Swashplate
mixer« menu, page 220.
Swashplate linearization
After selecting the “Linear. swashpl.” line with the 
selection keys of the left or right four-way button, the
entry field will be framed:
3Sv(2rol)
SEL
Linear. swashpl.
Swashplate
no
Rotor direct
right
Heli type
Pitch min. back
The “yes” entry will prevent undesired side effects
such as pitch change due to a roll function or tension
between swashplate servo rods.
This type of tension can arise when effected servos
strain for different displacement positions due to travel
which deviates from one another.
Linearizing will require a bit of familiarization on the
part of the pilot because, in order to linearize the
entire rotation travel of the servo arm, servo travel
is reduced in small control movements – similar to a
pronounced exponential setting.
Rotor direction
After selecting the “Rotor direction” line with the 
selection keys of the left or right four-way button, the
entry field will be framed:
3Sv(2rol)
SEL
Linear. swashpl.
Swashplate

Heli type
Pitch min. back
After a tap on the center SET key, the main rotor’s
direction of rotation is entered in the “Rotor direction”
line with the selection keys of the right four-way but-
ton:
• “right”
The main rotor turns clockwise when viewed from
above.
• “left”
The main rotor turns counter-clockwise when
viewed from above.
A simultaneous tap on the  or  keys of the
right four-way button (CLEAR) will set the option to
“right”.
