THR Curve/Throttle Hover trim
THR Curve
This function adjusts the throttle operation curve
for each condition for optimum the engine speed to
throttle stick movement.
A throttle curve from linear operation to smooth
curve can be set. Adjustment to the curve you want
to use is possible by using the 18MZ's powerful
Curve Edit Function. Up to 17 curve points can be
set, however, when the 5 points and other point data
is used, a smooth curve can be easily created by
reducing the number of points of to 5 and entering
the specified value at the corresponding points.
● Return to Model Menu
● Touch the [THR Curve] button in the Model
Menu to call the setup screen shown below.
Normal curve adjustment
● Normal curve creates a basic curve centered
around hovering. Use it along with the normal
pitch curve and adjust so that up/down control at
a constant engine speed is easiest.
Idle up curve adjustment
● Set a normal up curve that maintains a constant
speed at all times, even when operation which
reduces the pitch was performed in flight. Create
a curve matched to loop, roll, 3D, or other
purposes and the idle up curve according to the
performance.
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 mode.
Setting method
● Group button: When you also want to enter the
data to all other conditions, enter the data in the
group mode (GRP). When doing so, the same
settings are input to all the other conditions.
When you want to set date into each condition
independently, select the single (SNGL) mode.
● The curve graph display mode can be selected.
This is convenient when checking curves other
than the one being set.
[Sngl]: Displays only the curve being set.
[Fine Tuning]: When Throttle Hover trim is used,
a curve with trim adjustment added is also
displayed.
[All Cond.]: Displays the throttle curve of all the
conditions. The curve of the condition currently in
use is indicated by a bold line.
[PIT&THR]: The pitch curve of the condition
currently in use is also displayed.
● The pitch curve setup screen can be called with
one touch. This is convenient when alternately
adjusting these curves with the pitch curve.
● The servo speed can be set. Adjust the throttle
speed when the throttle is too sensitive
