GOAL of EXAMPLE:
STEPS:
INPUTS:
THROTTLE CUT
:
The
THR-CUT
function is used to kill the engine at the end of a flight. The engine can be stopped with
one touch of any switch, eliminating the need to move the trim to kill the engine and then readjust prior to each flight. The
helicopter
THR-CUT
includes an ON/OFF throttle position (normally a little above idle). You must move the
T
HROTTLE
S
TICK
back below the set point before the
THR-CUT
function can be reset, to avoid sudden engine acceleration. For a detailed
example of throttle cut setup, see
ACRO
p. 33.
Note
: Be sure to add the step of setting a trigger point by cursoring to
THR
, then putting the
T
HROTTLE
S
TICK
in the desired position and pressing and holding the dial for one second.
Notice that this function cannot be reversed to trigger only
above
the stick point.

Set up Normal Flight Condition
Throttle/Collective Pitch Curves
and Revo.
Base point
: Adjust base point of
throttle curve until engine idles
reliably on ground. Adjust base point
of collective pitch curve to achieve -4
degrees of blade pitch.
Apply throttle until the model sits
"light" on its skids. Adjust base point
of
REVO
. until model does not rotate
its nose at all.
Hover point
: Adjust collective pitch curve
to +5 degrees. Ease heli into a hover.
Land/shut engine off. Adjust throttle
curves and rudder trim. Repeat until
model hovers smoothly at half throttle.
Rapidly apply throttle from 1/4 to 1/2
stick. Adjust
REVO
. points 2 and 3
until the model does not rotate its
nose upon throttle application.
High point
: Adjust collective pitch
curve to +8 to +10 degrees. From
hover, throttle up rapidly. If engine
bogs, increase the throttle curve. If
engine over-revs, increase the
collective pitch curve at points 4 or 5.
Apply full throttle while hovering, then
descend back to hover. Adjust
REVO
.
until the nose does not change heading.
