Program description - Stick mode | Helicopter models
This option is available on the
mc-20
HoTT transmitter only.
Both sticks are equipped for digital trim-
ming. With each brief push (one “click”) on
a trim switch-key it will change its neutral position by
one increment. Holding the trim switch-key longer will
cause trimming to run in the corresponding direction at
increasing speed.
The current position is shown on the screen and the
adjustment is also made “audible” with acoustic tones.
This makes finding the mid-point during flight easy,
without looking at the screen. If the mid-point is over-
run, a brief motion pause will be inserted.
Current trim values are automatically stored when a
model memory change is made.
By default the digital trims of the
mc-16 HoTT and
mc-20 HoTT transmitters always apply to each
flight phase separately within a particular model mem-
ory – with the exception of the throttle / collective pitch
stick trim, generally abbreviated to control function
“C1” (channel 1).
If the »Stick mode« menu is unlocked, it is possible to
convert the digital trims from the default “PH” (phase)
setting to “GL” (global), although the C1 trim is always
“global”, i. e. it is independent of flight phases.
This settings are visualized in the base screen by a
“shadow” on trim bars:
• shadow present = global,
• no shadow = flight phase dependent.

In the following screen-shot of the base display of a
mc-20 HoTT transmitter with »Stick mode« un-
locked (as shown in the second screen-shot on the
right under the title ”Tr” column”), the tail rotor trim is
shown as “flight phase dependent”; this is the left /
right function of the left-hand stick, and assumes the
default “Mode 1” transmitter configuration:

• “TL“ (Throttle Limit)
C1 trimming operates as idle trimming when the
“throttle limit” function regulates the motor for start-
ing, see »Control adjust« menu, page 122.
• “TA“ (Throttle Autorotation)
C1 trim operates as idle trim exclusively in the «Au-
torot» flight phase.
This makes it possible to assign a principle (fixed)
preset AR throttle position in the »Helicopter mix-
er« menu, page 198, e. g. during autorotation
practice with the trim function “varied”.
• “PT“ (Pitch)
Due to internal coupling, C1 trimming acts equally
on all pitch servos available without influencing the
throttle servo.
A simultaneous tap on the or keys of the right
four-way button (CLEAR) will reset the option back to
“TL”, “TA” or “PT”.
