PROFI TX
Trim
Display of the throttle trim value
Lower limit
Defines the lower limit for the throttle curve to ensure safe idle speed. This
setting is overridden in the auto-rotation flight phase (AUTOROT).
Not required for models with electric power system: Thus, set it to 0%. The
flight phase-specific throttle trim is added to the lower limit and thus increases
the lower limit by the trim value.
The horizontal dotted line in the graph shows the position of the throttle limiter
in all flight phases.
Run-up Time
Slow function for throttle: 0.0s to 6.0s
This parameter defines the time for running up from idle to full throttle. This
does not affect the run-down time.

Throttle curves (Governor OFF)

For each of the flight phases 1 to 4 a separate throttle curve with 7 points can be
configured to achieve optimum adaptation of the motor power to the throttle curve
setting for the respective flight phase.
The aim is to achieve a constant system speed over the entire collective pitch
range. Ultimate fine-tuning of the throttle curve is only possible in flight and
depends on many parameters (motor power, motor setting, power characteristics,
setting for the collective pitch curve, rotor blades used, etc.). If a parameter is
changed, fine-tuning of the throttle curve must usually be repeated.
Tip: Allocate a digi-adjuster to the curve point to be configured. Refer to page 168 in
section "Digi-adjuster" for details.
To assist configuration the current position of the collective pitch stick is displayed
in the graph as a vertical dotted line.
