Stick Mode - GRAUPNER MC-20 HoTT Programming Manual

Joystick setting
Setting stick mode 1 through 4
Both joysticks are equipped for digital trimming.
When turning trim wheels, every "click" will shift the
joystick's neutral position by a certain value.
The current position is shown on the screen and
the adjustment is also made "audible" with acoustic
tones. This makes fi nding the mid-point during fl ight
easy, without looking at the screen. If the mid-point is
overrun, a brief motion pause will be inserted.
Current trim values are automatically stored when a
model memory change is made.
Furthermore – except for global control
function trimming of the throttle/brake joystick,
commonly referred to as control function "C1"
(channel 1) – digital trimming is effective within a
model memory location selectively as either a global
parameter (i.e. consistent in all fl ight phases) or as
a fl ight-phase specifi c parameter. This specifi cation
as "global" or "phase" is made in the »Stick mode«
menu described here, whereas software-side C1
trimming is generally set to "global", i.e. independent
of fl ight phases.
This setting is visualized in the base screen by a
"shadow" on trim bars:
• shadow present = global,
• no shadow = fl ight phase dependent.
In two corresponding fi gures below, elevator
trim – shown in the middle text column with its default
setting "global" – then in the right column set to fl ight
"Phase" specifi c.

This menu, adapted for winged models, permits the
four digital trim wheels to be set and their trim effects
to be assigned, selectively, as a "deceleration" factor
to control functions 1 through 4.
The desired line can be reached by using the
selection keys of the left or right touch pad. Once the
appropriate function fi eld has been selected and then
the center SET

Trim
"Global": The position of the respective trim wheel
is effective "globally" for all fl ight-phases
programmed for the given model, page 140.
SET "Phase": The position of the respective trim wheel
is effective on a phase-specifi c basis and
will be automatically stored upon change
0.0s
of fl ight phase so that the setting is again
available following a return to this fl ight
0.0s
phase.

A simultaneous tap on the

right touch pad (CLEAR) will reset the option back to
"Global".
Trim steps
The four digital trim wheels shift the neutral point of
the respective joystick in the given direction by one
adjustable increment, as set here, for each "click".
This is where the increment size (step) can be
adjusted for a given direction, whereby maximum trim
travel, independent of the selected number of trim
steps, is always about ±30 % of control travel.
After selecting the "Tr. step" column (trim steps) and
the desired trim control with the
of the left or right touch pad, the corresponding entry
fi eld will be framed.
