Throttle cut (THR-CUT) (ACRO/HELI): provides an easy way to stop the engine by flipping a switch (with T

HROTTLE

S

TICK

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.

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.

STEPS:

INPUTS:

engine running to confirm.
