GOAL of EXAMPLE: STEPS: INPUTS:
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

rotate its nose at all.

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 6 or 7. Apply full throttle
while hovering, then descend back to
hover. Adjust

THROTTLE CUT:
The
THROTTLE-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

little above idle). You must move the THROTTLE STICK back below the set
point before the
THROTTLE-CUT
function can be reset, to avoid sudden engine
acceleration. For a detailed example of throttle cut setup, see
ACRO
p. 41.
Note: Be sure to add the step of setting a trigger point by cursoring to
THRO
, then putting the THROTTLE STICK 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.
