Throttle cut (THR-CUT) (ACRO/HELI): provides an easy way to stop the engine by flipping a switch (with THROTTLE STICK
at idle). The movement is largest at idle and disappears at high throttle to avoid accidental dead sticks. In HELI, there is an
additional setting, THR. See p. 82.
The switch's location and direction must be chosen. It defaults to OFF to avoid
accidentally assigning it to a switch, which might result in an unintentional dead stick in
flight. Please see for IDLE-DOWN and THR-CUT on p. 33.
GOAL of EXAMPLE: STEPS: INPUTS:
*Normally, a setting of 10-20% is sufficient. Viewing the carburetor barrel until it fully closes is adequate to get an approximate setting; then test with
engine running to confirm.

Decrease the throttle setting (at idle) to
stop the engine with the flip of a switch.
(Note that you MUST assign a switch.
The default is NULL. We recommend
S
WITCH C in the down position, with
IDLE-DOWN programmed to S
WITCH C
in the center and down positions.)
