This function is used to stop engine after flight is finished. You can set e ngine powered on/ off, without
shifting trim stick to power off and set again every time before flight. Throttle shut for helicopter includes
THR ON/ OFF (position above idle down). Before resetting throttle cut, throttle stick must keep below
setting point to avoid a sudden speeding up.

Important note: The IDLE-DOWN function is not normally used when starting the engine, and its
accidental operation may keep your engine from starting. The AT9 warns that IDLE-DOWN is on when the
transmitter is turned on. Be sure to turn off the function, or override the warning by pressing CURSOR lever
if you intended the function to be on.
This may be assigned to any switch/position. Some modelers accidentally assign IDLE-DOWN to one side
of a switch and THR-CUT to the other. There is no "normal" setting to start the engine. By default
IDLE-DOWN is get to SWITCH C center and down. This works well with THR-CUT also on SWITCH C
down. The SWITCH C up is normal flight/starting, center for slower maneuvers/landing, and down to cut the
engine. If you assign IDLE-DOWN or THR-CUT to the spring-loaded TRAINER SWITCH H or F, then use
the trainer function, you may risk loss of throttle control or dead stick for your student.
