2.9 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.
