Pitch min
After selecting the »Pitch min.« (pitch minimum) line
with the  selection keys of the left or right four-way
button, the entry field will be framed:
Heli type
Swashplate 3Sv(2rol)
Linear. swashpl.
Rotor direct
Pitch min.
The "Pitch min." line is used to adapt the actuation
direction of the throttle/pitch stick to personal control
preferences. All other helicopter program options which
involve throttle and pitch functions, e. g. throttle curve,
idle trimming, tail rotor mixer, etc., are dependent on
this setting.
Tap the centre SET key of the right four-way button.
The operating direction of the throttle/pitch stick will
be displayed in inverse video. Now choose the variant
needed with the selection keys of the right four-way
button.
104 Program description - Helicopter type
These mean:
• "front"
minimum pitch setting when the pitch stick (C1) is
"forward", i. e. away from the pilot.
• "back"
minimum pitch setting when the pitch stick (C1) is
"back", i. e. toward the pilot.
no
A simultaneous tap on the  or  keys of the right
right
four-way button (CLEAR) will set this option to "back".

Notes:
• The C1 trim only affects the throttle servo
or the collective pitch servos, depending
on the settings in the "Tr" column of the
»Stick mode« menu, which is available as stand-
ard on the mc-20
• Up to firmware version 1102 the so-called "throt-
tle limit" is set by default, see text beginning page
122, by way of input "Lim." in the »Control ad-
just« menu with which the throttle servo can be
limited, independent of the pitch servo, in the full
throttle direction. From firmware version 1103 it
can be optionally set.
Pitch
• Since a given user's models will typically be oper-
ated with the same pitch-min direction, this spe-
cification can be conveniently preselected in the
"transmitter-specific" »Basic settings« menu,
page 269. This specification will then be adopted
automatically when a new model memory is creat-
ed in the »Helicopter type« menu but, if desired,
can be adapted on a model-specific basis as de-
scribed.
Expo throttle limit
After selecting the "Expo thro lim." line with the 
selection keys of the left or right four-way button, the
entry field will be framed:
The "Throttle limit" function described in the »Control
adjust« menu can be assigned an exponential charac-
teristic curve.
With the selection buttons, a value between ± 100% of
HoTT transmitter only.
the rate of progression can be adjusted by pressing the
central
For example, it is practical to have the throttle limit – by
default, the right-side proportional rotary slider – also
regulate the idle setting. Further details about the throt-
tle limit can be found in the text for the »Control ad-
just« menu beginning page 122,.
