Parameter: D/R (Dual Rate)

Aileron, elevator, rudder

10% to 100%

Dual Rates are designed to modify the sensitivity of a
transmitter control. For example, if the Dual Rate pa-
rameter for a control function such as aileron is set to
50%, you can reduce the model's aileron travel to 50%
by operating the "D-R" switch (= L), and thereby obtain
finer aileron control. The control curve in the graph al-
ters appropriately when you operate the "D-R" switch.
Parameter: Travel

for controls:
Aileron, elevator, rudder
Roll, pitch-axis, yaw
for controls:
Adjust. range
0% to 100%
One value for each flight phase
Can be assigned to a 3D digi-adjustor
F
(
11.2.2.)
The Travel parameter offers the same facility as Dual
Rates: the sensitivity of a transmitter control can be
modified (reduced). The difference with Travel is that
the effect can vary from one flight phase to another, i.e.
you can set a different value in each flight phase. For
example, in the "NORMAL" flight phase = 100% for
maximum control response; in the "SPEED" flight phase
= 70% for finer control.
Note:
At any one time only one value can be displayed for the
active flight phase. If you wish to change the values for
other flight phases, make sure that you select the ap-
propriate flight phase before you change the setting.
Parameter: Expo
14.7.
for controls:
Aileron, elevator, rudder
Roll, pitch-axis, yaw
for controls:
Adjust. range
-100% to +100%
Can be assigned to a 3D digi-adjustor
F
(
11.2.2.)
Expo can be used to modify the effect of the trans-
mitter control in the area around centre. At Expo = 0%
the control's response is linear. The effect of negative
Expo values is that a command generates small control
surface travels in the area around centre, giving the pi-
lot finer control. This is the most common application
for exponential (Fig. 1).

The effect of positive Expo values is to increase control
surface travels around neutral. The model is "sharper" in
response. Expo does not affect the servo end-points, i.e.
full travel is still available if necessary.

for controls: Spoiler, flap

One value for each flight phase
Can be assigned to a 3D digi-adjustor
F
(
With this parameter you can generate fixed control sur-
face travels for each flight phase, which cannot then be
changed by the associated transmitter control. If Fixed
value is set to OFF, the transmitter control operates
the control surface in the normal way.
A typical example is the thermal and speed settings on
a four-flap glider (e.g. F3B). For example, if you activate
the THERMAL flight phase, the ailerons and camber-
changing flaps move to a new neutral position opti-
mised for thermalling (e.g. thermal flap, fixed value = -
30%). If fixed value is set to OFF for the NORMAL flight
phase, the neutral position of the ailerons and flaps is
infinitely variable using the flap control when you select
the Normal flight phase.
Note:
At any one time only one value can be displayed for the
active flight phase. If you wish to change the values for
other flight phases, make sure that you select the ap-
propriate flight phase before you change the setting.
Parameter: Slow (speed)
14.9.
for controls:
Throttle, spoiler, flap, retracts
Retracts
for controls:
Adjust. range
0.1 to 4.0 s
Can be assigned to a 3D digi-adjustor
F
(
The Slow parameter can be used to alter the time over
which the transmitter control moves the servo from one
end-point to the other. The usual application for this is
to slow down a process which is operated by a switch.
Examples:
Retracts: extend slowly, so that the undercarriage re-
tract sequence looks true to scale.
Spoiler (airbrakes): extend slowly, so that the model
does not carry out any jerky movements when the
brakes are deployed.
