THROTTLE HOLD (HLD)
This function moves the throttle servo to idle
during auto rotation. Either a Manual mode or an
Auto mode can be selected. In the manual mode,
the throttle servo is held by turning on the throttle
hold switch. In the auto mode, the throttle servo is
held when the throttle stick is moved past the set
position on the low throttle side after the throttle
hold switch is turned on.
A delay up to the servo hold position can be
set. Throttle trim can be turned on and off during
throttle hold, but it is usually turned on.
