Idle Down(Acro Only) - RadioLink AT9S PRO Manual

Goals
Flip switch to
decrease the rate
until engine stops.
(NOTE: you MUST
assign a switch to
control which default
is NULL)
HELICOPTER
This function is used to stop engine after flight is finished. You can set engine 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.
Notification: trigger point setting step: under the menu THR CUT, choose THRO by DIAL, and press
PUSH and move the throttle stick to trigger point, then press and hold PUSH one second to save. This
function only when the throttle stick moves below trigger point.
2.3.9 IDLE DOWN (ACRO only)
Lowers the engine idle for: set for sitting on the runway prior to take off,
stalls and spins, and landings. The normal idle setting is a little higher for
easier starts and safe flights with less risk of dead sticks.
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.
