Engine idle management:
IDLE-DOWN
and
THR-CUT
: functions which work with the digital
THROTTLE TRIM
to provide
a simple, consistent means of engine operation. No more fussing with getting trim in just the right spot for landings or take
offs! For additional engine adjustments, see
THROTTLE-NEEDLE
(p. 65) and
THROTTLE DELAY
(p. 66).
IDLE-DOWN
(
ACRO
only): lowers the engine idle for: sitting on the runway prior to take off, stalls and spins, and landings.

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
10C 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.

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 set to
SWITCH C
center and down. This works well with
THR-CUT
also on
