PIT Curve/Pitch Trim
PIT Curve
This function adjusts the pitch operation curve
for each fl ight condition for the optimal fl ight state
relative to movement of the throttle stick.
The pitch curve can be freely selected from linear operation
curve to smooth curve, and adjusted to match the curve
you want by means of the T14MZʼs powerful Curve Edit
Function (6 types of curves can be selected). Up to 17 points
can be set for linear or curve types. However, when using
the 3 points or 5 points specifi ed to create a curve, a simple
and smooth curve can be created by selecting the curve type
and reducing the number of input points to 3 or 5, and then
entering the specified value at the corresponding points
that you created.a curve, a simple and smooth curve can be
created by selecting the curve type and reducing the number
of input points to 3 or 5, and then entering the specified
value at the corresponding points that you created.
● Return to Model Menu
● Touch the [PIT Curve] button in the Model Menu to
call the setup screen shown below.
● There are 4 types of display. The curve of all the
conditions or the pitch and throttle curves can be
displayed on one screen.
● Linear type is 9 points, but for
simple use, 4~5 points are
suffi cient.
● Normally use Separate.
● Trim can be used
as hovering pitch
and pitch trim.
The high and low
side pitch can
be fi ne-tuned.
● Units can be selected from [%] and [Deg]. When [Deg] is
selected, the rotor pitch angle is displayed and becomes the
setting standard. When [Deg] was selected, the high, center,
and low pitch angles are enterd.
● Can be copied to the pitch trim adjustment position.
● When the [Angle] button is touched, the pitch angle input
screen is displayed. Input the maximum pitch, center, and low
pitch.
Normal curve adjustment
● For normal curve, usually use [Line] type and
create a basic pitch curve centered about
hovering. Use this function together with the
THR Curve (Normal) function and adjust the
curve so that up/down control is best at a
constant engine speed.
Idle up curve adjustment
● For the high side pitch curve, set the
maximum pitch which does not apply a
load to the engine. For the low side pitch
curve, create curves matched to loop, roll,
3D, and other purposes and use the idle up
curves according to the performance.
Note: When the curve type is changed, the data is
reset.
Throttle hold curve adjustment
● The throttle hold curve is used when
executing auto rotation dives.
Operation precautions
WARNING
When actually starting the engine and
flying, always set the idle up condition
switch to [OFF] and start the engine in the
idling state.
