Throttle curve
Quick-Link-specifi c setting of the throttle curve
In the basic transmitter display, use a fi nger or the
provided stylus to touch the gear icon labelled "F":

Flight-phase-dependent setting of throttle curves
If you have created Quick Links in the "Q.Link"
submenu, page 168, and assigned them an
appropriate name, "NORMAL" (for example) appears
in green at the top right of the display. Activate the
corresponding switches if desired to switch between
Quick Links.
Notes:
•
The "Throttle" setting for the autorotation
phase is described in the menu "THR.
HOLD", page 190.
• The value displayed in the line "Throttle limit" at top
left only indicates the position of the gas limiter.
Throttle curve
The throttle curve can be specifi ed by up to 7 points, the
so-called support points, along the entire control stick
travel depending on the Quick Link:

Support points can be set, changed and deleted in the
same manner as described in the previous section,
"Pitch curve", starting on page 175. 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
speed controller
This setting only refers to the control curve for the
throttle servo or the speed controller.
The appropriate adjustment of the throttle curve to a
helicopter equipped with a governor will be addressed
below.
• The control curve should be set so that the
carburettor 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 exception
of autorotation fl ight).
• For the hovering point which is normally in the
center of the control, the carburettor setting or
performance 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 control
stick, initially set the throttle curve so that a gas
motor runs signifi cantly faster in comparison to idling,
and the clutch engages reliably.
Both a gas and electric motor are stopped
using the throttle limiter within the Quick
Link.
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 the mz-18 HoTT and mz-24
HoTT transmitters than by using a gas preset.
To start the gas motor, make sure that the gas limiter
is closed; that is, the carburettor can only be adjusted
by trim its idle position. Make sure to follow the safety
instructions on page 185. If the throttle is set too
high when the transmitter is switched on, a visual and
acoustic warning are generated.
