Hovering pitch trim
The Hovering Pitch trim 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 mode to the
single mode (initial setting) before setting.
● Set the function to ACT [ON].
● Select the adjustment knob.
