Throttle curve

Phase-specifi c setting of the throttle control curve

As for the setting of the pitch curve also for the throttle
curve there is a curve mixer available in every fl ight
phase. Also in this mixer can however only be pro-
grammed if required not linear mixer actions analog
to the control stick travels.
Phase-dependent settings of the throttle curve
The here mentioned sub-menu offers the possibility
of phase specifi c settings. Recognizable on the top
left side of the display in green color is displayed the
phase name. As standard is displayed the name of the
phase 1, which is indicated by the name "NORMAL"
or "PHASE 1". As soon as you will have defi ned one
or many other phases in the "PHASE" menu, you will
be able to switch among those phases. Activate the
corresponding switch or switches if desired to switch
between the phases.

Tips
• The "Throttle" setting for the autorotation phase is
described in the sub-menu "THR.HOLD", .

• If the "THR.Limit" has been activated in the menu

»CTL Set« through the assignation of a control, its
actual position in the line "THR:Limit" in the upper
left side of the display is displayed in numerical value.

The throttle curve can be specifi ed by up to 7 points,
the so-called support points, along the entire control
stick phase specifi c travel:

Sequence
At the beginning, fewer support points are required
to set the throttle curve. It is, however, highly recom-
mendable to start with three support points.
These three endpoints, the two endpoints "Pitch low
(L)" = -100% control travel and "Pitch high (H)" =
+100% control travel, as well as a point to be placed
in the control, center describe a linear characteristic
for the pitch control curve.
Support points can be set, changed and deleted in
the same manner as described in the previous sec-
tion, "PIT.CRV". First specify the throttle curve using
three points, that is, the two end points "L" and "H",
as well as the other set point "1" in the control center
in order to harmonize the motor performance curve
with the pitch curve.

Helicopter with gas motor or electric drive with a
governor
Notice
The appropriate adjustment of the throttle curve
to a helicopter equipped with a governor will be
addressed below.
This setting only refers to the control curve for the
throttle servo or the governor.
• The control curve should be set so that the carbu-
rettor is completely open when the throttle/pitch
control stick is in end position, or the actuator of
an electric helicopter is fully enabled (with the ex-
ception of autorotation fl ight).
• For the hovering point which is normally in the cen-
ter of the control, the carburettor setting or perfor-
mance control of the motor control unit needs to
be coordinated with the pitch curve to produce the
desired system speed.
• At the minimum position of the throttle/pitch con-
trol stick, initially set the throttle curve so that a
gas motor runs signifi cantly faster in comparison
to idling, and the clutch engages reliably.
Notice
Both a gas engine and electric motor are stopped
using the THR.Limit within the phase.
It is unnecessary to program two quick links
("with throttle preset" and "without throttle preset" to
thereby "gift" a quick link to the gas preset) which is
sometimes used in other remote control systems to
accomplish the same purpose since the system
speed can be increased below the hovering point
much more fl exibly and sensitively with the
included in the mz-24 HoTT Pro transmitter than by
using a gas preset.
