Pitch Curve - JR ProPo DSX11 Operation Manual

Pitch Curve

Because the operation method being based on the Throttle
Curve described in the previous section, setting should be
carried out after you have understood the Throttle Curve
setting method.
In the Pitch Curve systems, there are six independent
types, consisting of NORM, ST-1, ST-2, ST-3, ST-4, and
HOLD which can be set by changeover (when Throttle Hold
is set). The points in each of the systems are multipoint as
in the Throttle Curve, and are independent in all the
systems.
Note that when setting the pitch curve for Throttle Hold, it
will be necessary for the Throttle Hold function to be set to
Flight Mode Switch Position
High Pitch Lever
Offset Setting
This will change according to the stick position.
No Display: Setting is not possible
Switch Position Changeover
The position changeover should be carried out with the
corresponding switch operation.
Change over to the Mode that you wish to set by using each
of the corresponding switches.
Switch Position
NORM: Normal
ST-1: Stunt 1
ST-2: Stunt 2
ST-3: Stunt 3 When Flight Mode
ST-4: Stunt 4 Extension is set to ACT
HOLD: Throttle Hold When Throttle Hold is set to ACT
Exponential Curve (EXP) Function
Curves are independent for each system, and it is possible
to select a straight line or an exponential curve. By setting
EXP to "ON" using the dial, the sequential line curve will
become an exponential curve in which the changes in the
output values close to each of the points will become
smoothed. To disable this function, press the dial again to
switch it OFF.
Press the dial.
High Pitch Trim Lever
In the initial settings, the High Pitch Trim Lever at the rear
right of the transmitter will be set to "INH" (operation
inhibited). By setting this to "ACT", the "HiPIT" item will be
displayed on the screen, and the High Pitch Trim will
operate. Setting of the adjustment amount can be carried
out using RATE. The high side end of the created pitch
curve can be moved up and down using the lever. Because
the pitch curve that was set will usually be finely adjusted to
become close to the target curve, this pitch trim is only used
for temporary processing at the adjustment stage, and
should normally be kept set to the center position. Further,
this lever can also be allocated to "INH" or another opera-
tion. For more details, read the Device Select section
(System Setting Mode).
ACT, and use will not be possible when the function is set to
INH.
To make it possible to use HOLD, first carry out setting
using Throttle Hold. By doing this, it will become possible to
carry out curve setting during Autorotation even in the
HOLD item.
Note that in this situation, the Hold switch will have priority
of operation regardless of the position of the Flight Mode.
Giving adequate consideration to the helicopter body
settings indicated by the helicopter manufacturer, carry out
the curve settings in each position to match the purpose.

Point Numerical Value Input
The numerical value setting for each point is also carried
out by rotating the dial to highlight the point that you wish to
set, then pressing the dial to change the point to the condi-
tion where it is enclosed by a border as shown in the figure
below. Rotating the dial in this condition will increase or
decrease the numerical value. Pressing the
condition will return the values to the preset condition. The
preset values of each point are as described below.
Regarding the addition and deletion of the actual points,
refer to the Throttle Curve section.
Press the dial.
When preset is carried out,
Hovering Pitch
The Hovering Pitch operation should be considered as being
the same as Hovering Throttle. (Refer to the Throttle Curve
item.)
