THRO CURV – THROTTLE CURVE
A-23
A linear throttle response can be obtained with the THRO
CURV function by causing the throttle servo to move in an
exponential fashion. In other words, the servo will move
very little for the first ¼–½ of stick movement, and then
move more rapidly as the stick is advanced further.
THRO CURV can also be used to set up a special throttle
response where the engine quickly comes up to a certain
rpm and then advances very slowly to provide precise rpm
control for a specific throttle range before continuing on
to full throttle. Such a curve is useful for torque rolling,
rolling circles and other maneuvers where the throttle
response is to be slowed or flattened-out for a particular
throttle range.
If the Twin E. function has been activated for twin-engine
aircraft, independent throttle curves are available for each
engine to help eliminate any discrepancies in the throttle
response between the two engines.
If the aircraft is equipped with an engine that has a non-
linear response, set up a throttle curve as described below.
1. Highlight and select THRO CURV in the FUNC.LIST.
Two different throttle curves may be defined and they
are named or otherwise referenced by Pos0 and Pos1.
2. If there is a need to have 2 throttle curves (i.e. a
regular curve and a curve for torque rolling), use the
Selector to highlight SW SELECT and a list of available
Flight Modes and switches appears. Select the Flight
Mode(s) (FM0, FM1, or FM2) and/or switch(es) that is
to select between the 2 curves. The switch will be used
to select between the Pos0 curve and the Pos1 curve.
Highlight and select Pos0 to toggle between the Pos0
and Pos1, in order to display and adjust the 2 curves.
