Pit.crv - Pitch Curve - GRAUPNER mz-24 Pro Programming Manual

PIT.CRV
Phase-Specific Pitch Control Curve Setup
Use this function to set adjustments to the pitch of he-
licopter blades at certain stick positions. For exam-
ple, when the control stick is all the way forward with
the intent for the helicopter to quickly fly straight up,
the curve should be programmed for maximum pitch
on the blades. Conversely, when the helicopter is shut
down for a stop, the curve should be programmed for
little or no pitch on the blades.
To adjust these settings, from the main display press
the FUNCTION menu gear icon (blue "F") to bring up
the FUNCTION submenu screen:

A curve mixer is available in every flight phase for
pitch curve settings. However, linear mixers cannot
be programmed for actions analog to the control stick
travels.
Pitch min Line
In the mz-24 Pro, the helicopter program defaults the
"rear" throttle to the Pitch min position.
This option allows users to easily reverse the pitch
control stick control direction from the standard pre-

Phase 2, Phase 3, etc.) To define multiple phases,
refer to the FUNCTION submenu Phase section (page

different switch. To change the phases, activate the
corresponding switch(es).
Pitch Curve Setting
Use this display to adapt the pitch curve as needed,
and assign to different phases if necessary:

The example graphs represent the curve charac-
teristics directly, independent from the actual di-
rection selected on the pitch control stick.
The pitch control curve can be specified by up to 7
points (termed "support points") along the entire con-
trol stick travel.
During initial setup, fewer support points are required
to set a pitch curve. However, it is recommended to
start with at least three support points.
These three endpoints describe the linear character-
istic of a pitch control curve: the two endpoints Pitch
low (L = -100% control travel) and Pitch high (H =
+100% control travel) and the control (placed in the
center).
