14.2.4. Parameter „D/R“ (Dual-Rates)
F
can be assigned to a 3-D digi-adjustor
10% to 100%
Dual Rates enable the user to change the control sensi-
tivity of the model. For example, if the Dual Rate pa-
rameter is set to 50%, you can reduce the model’s con-
trol surface travels to half of normal by operating the
assigned switch.
14.2.5. Parameter „Trvl“
This parameter is used to determine the percentage of
full servo travel which can be obtained using the associ-
ated transmitter control.
14.2.6. Parameter „Expo“
F
can be assigned to a 3-D digi-adjustor
-100% to 100%, 0% = OFF
This parameter allows you to assign an exponential
characteristic to the transmitter control. If Expo is 0%,
the transmitter control is linear in effect. Negative Expo
values have the effect that control in the area around
the centre position produces reduced control surface
travels, giving you fine control around neutral. Positive
Expo values have the opposite effect: the control sur-
face travels are greater around the centre position.
The Dual Rates function (Î 14.2.3.) reduces total servo
travel, whereas Expo does not change the end-points.
This means that full travel is always available when re-
quired.
14.2.7. Parameter „Fixed value“

separately variable for each flight phase
F
can be assigned to a 3-D digi-adjustor
-100% to 100%, 0% = OFF
This parameter is used to generate control surface trav-
els which cannot be changed by the associated trans-
mitter control.
A typical example for this function is a fixed flap posi-
tion for launching the model. When you switch on the
LAUNCH flight phase, the flaps are required to move
automatically to the launch position. In NORMAL flying
the flaps are controlled using a transmitter control (e.g.
slider F) in the normal way.
14.2.8. Parameter „Run time“ (Slow)
F
can be assigned to a 3-D digi-adjustor
0.1 to 4.0 s
The run time parameter allows you to determine the
time over which a transmitter control moves from one
end-point to the other. This enables you to set up grad-
ual travel of any control system, even if it is triggered by
a switch.
Examples:
Extending retractable undercarriage slowly, so that
the process operates at scale speed.
Lowering or raising flaps slowly, so that the model
does not make any abrupt movements when you
change the flap setting.
14.2.9. Parameter „Idle“ (idle trim)
Throttle control only
This function alters the operation of the idle trim, as the
name indicates. From the graph in the H Throttle menu
you will see that the throttle trim only affects the range
up to centre (1/2-throttle). The area from centre to full-
throttle is not affected.
14.2.10. Parameter „Collective pitch“
(Coll. pitch curve)
I affects the active model only
Range +/- 100%

one coll. pitch curve for each flight phase
F
each curve point can be assigned to a 3-D digi-
adjustor (Î 10.2.2)
Adjusting the collective pitch curve for helicopters is
done in the menu H Control/Collect. Each flight
phase can have a separate curve, to adopt the curve to
each individual phase.
Example 1: Coll. pitch curve phase Hover
„Flatened“ curve between hover and collective pitchmi-
nimum for more sensitive hovering and landing.
