Parameter Mode (Throttle Trim); Parameter D/R (Dual-Rate); Parameter Trvl (Travel); Parameter Expo - Multiplex Royal SX 9 Instructions Manual

!
Note:
If the associated transmitter control is not at
centre, then any alteration in the trim increment
size automatically affects the trim value (trim
setting). In this case you must adjust the trim
accordingly.
For general-purpose use an increment size of 1.5%
has proved a good compromise. However, for very
fast models with accurate control surface linkages, or
models with very large control surface travels (e.g.
fun-fly types) an increment size of 1.5% may be too
large. In this case you should set Step to 0.5%, which
will provide very fine trim control.

Parameter Mode (throttle trim)

15.4.3.
The trim of the transmitter control Throttle enables
the user to adjust and fine-tune the idle speed in
models with internal-combustion engines. The pa-
rameter Mode also determines the throttle trim's
method of working:
Mode = HALF: the trim of the Throttle control only
affects the range from idle to half-throttle.
Mode = FULL: the trim of the Throttle control affects
the full range from idle to full-throttle.

Parameter D/R (Dual-Rate)

15.4.4.
for controls:
Aileron, Elevator, Rudder
for controls:
Roll, Pitch, Yaw
10% to 100%
Adjustment
Can be allocated to a 3-D digi-adjuster
range:
( 20.1.)
The purpose of Dual Rates is to alter the sensitivity of
particular transmitter controls. If the Dual-Rate para-
meter for one control function (e.g. Elevator) is set
to 50%, you can switch to finer control of the model by
operating the switch assigned to Dual-Rate, thereby
reducing the travel of the model's control surfaces to
half. When you operate the switch assigned to Dual-
Rate, the transmitter control curve in the graph
changes accordingly:

Parameter Trvl (Travel)

15.4.5.
for controls:
Aileron, Elevator, Rudder
for controls: Roll, Pitch, Yaw
0% to 100%
Adjustment
Can be assigned to a 3-D digi-adjuster
range:
( 20.1.)

One value for each flight phase
The parameter Trvl works in a similar way to Dual-
Rate: it provides a means of influencing (reducing) the
sensitivity of a transmitter control. The difference with
Trvl is that the influence varies from one flight phase
to the next, i.e. you can set a separate value in each
flight phase. For example, in the flight phase NORMAL
= 100% for maximum control response, and in the
flight phase SPEED1 = 60% for finer control at high
speed:
Note:
At any one time the screen can only display the set-up
value for the active flight phase. If you wish to change
the values for other flight phases, please remember
that you must first activate the appropriate flight phase
before you actually alter the value.

Parameter Expo

15.4.6.
for controls:
Aileron, Elevator, Rudder
Roll, Pitch, Yaw
for controls:
-100% to +100%
Adjustment
Can be allocated to a 3-D digi-adjuster
range:
( 20.1.)

One value for each flight phase
Expo can be used to assign an exponential charac-
teristic to a transmitter control curve. At Expo = 0% the
transmitter control works in a linear fashion. The effect
of negative Expo values is that the transmitter control
generates small control surface travels around the
centre position, providing finer control for the pilot.
The effect of positive Expo values is that the control
surface travels are increased around the centre po-
sition. In either case the end-points of the travel are
unchanged when Expo is used, i.e. full travel is still
available when required:

Parameter Fixed Value

15.4.7.
for controls:
Spoiler, Flap
Adjustment
-100% ... OFF ...+100%
range:
One value for each flight phase.

Can be allocated to a 3-D digi-adjuster
( 20.1.)
This parameter can be used to generate fixed (flight
phase specific) control surface travels which cannot
be changed by the associated transmitter control. If
Fixed value = OFF, the control surfaces are con-
trolled directly by the relevant transmitter controls.
