FUTABA 9 CHP SUPER Instruction Manual page 34

Throttle cut (THR-CUT) (ACRO/HELI): provides an easy way to stop the engine by flipping a switch (with T
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. 87.
GOAL of EXAMPLE:
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 C in the down position, with
WITCH
IDLE-DOWN programmed to S
in the center and down positions.)
Where next?
*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.
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
STEPS:
Open BASIC menu, then open
THR-CUT function.
Activate the function. Choose desired
