110 Program description - Helicopter type
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 depend-
ent on this setting.
Tap the center
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.
Pitch
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.
A simultaneous tap on the

or

keys of the
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 standard on the
mc-20
HoTT transmitter only.
• The so-called “throttle limit” is set by default, see
text beginning page 127, by way of input “Lim.” in
the »Control adjust« menu with which the throttle
servo can be limited, independent of the pitch ser-
vo, in the full throttle direction.
• 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 268. 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:
Expo thro lim. 0%
SEL
Linear. swashpl. no
Rotor direct right
Heli type
Pitch min. back
The “Throttle limit” function described in the »Control
adjust« menu, see page 127, can be assigned an
exponential characteristic curve.
A pitch progression rate between -100 % and +100 %
can be set with the selection keys.
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 throttle limit can be found in the text for the
»Control adjust« menu beginning page 122.
