Hovering pitch trim
The Hovering Pitch function trims the pitch near
the hovering point. Normally, it is used with the
hovering condition. The hovering pitch can be fine
tuned for changes in rotor speed accompanying
changes in temperature, humidity, and other flight
conditions. Adjust the hovering pitch so that
rotor speed is constant. This function can be used
together with the Hovering Throttle Trim function
for more delicate operation.
Setting method
● When using only the hovering (normal)
condition, switch the group button to the
single mode before setting.
● Set the function to ACT [ON].
● Select the adjustment knob. Selection
example: LD or T6
● The trim operation mode (Mode: CTRM/
NORM) can be selected.
CTRM mode: Maximum change near center
by center trim operation (Does not change
at end of the stick movement)
NORM mode: Normal trim (linear) operation.
The advantage of using this mode is that
the hovering pitch can be adjusted without
changing the curve.
● Trim adjustment range (Range) setting
When this value is made small, trim can only be
used near the center.
● The trim rate can be adjusted and the
operation direction can be changed.
High Pitch/Low Pitch Trim
High Pitch/Low Pitch Trim is the pitch servo
high side and low side trim function.
Setting method
● When setting the adjustment knobs common
to all the conditions, set them in the group
mode.
● Set the function to ACT (ON).
● Select the adjustment knobs. Selection
example: LST (high side), RST (low side)
● The trim rate can be adjusted and the
operation direction can be changed.
● Trim acts as high side or low side trim with the
center as the standard.
