Mode switching

Basically there are four methods of assigning the
control functions aileron, elevator, rudder and throttle
to the two dual-axis sticks of the SMART SX transmit-
ter. Which of these options is used varies according to
the personal preference and habits of the model pilot.
The stick modes are defined as follows:
Mode 1: Right stick
Left stick
Mode 2: Right stick
Left stick
Mode 3: Right stick
Left stick
Mode 4: Right stick
Left stick
The SMART SX transmitter is available in two ver-
sions, each offering two stick modes. When you pur-
chase your set you must decide on one of the com-
binations, which is determined by the non self-cent-
ring throttle function.
•
SMART SX M-LINK Mode 1 + 3 (# 1 5300)
•
SMART SX M-LINK Mode 2 + 4 (# 1 5301)
The stick mode can be changed within the selected
combination. The first set (# 1 5300) can be switched
between Mode 1 and 3. The second set (# 1 5301)
can be switched between Mode 2 and 4.
If you wish to change the stick mode, please use this
procedure:

Locate the stick with two self-
centring planes (no throttle
function), and move it to the
top right corner, then press
the multi-function button for a
period of three seconds: you
will now hear an audible signal; the number of beeps indi-
cates the new stick mode. It is only possible to swap rudder
and aileron, as shown above, since the throttle function and
the elevator are permanently assigned, depending on the
set you have purchased. The setting is stored permanently
for each model.

Servo reverse

The direction of servo rotation can be changed for the three
control surface functions (= all except throttle). If any con-
trol surface operates in the wrong direction, it is a simple
matter to reverse the direction of operation for that function.
Locate the stick for the control
function you wish to reverse,
move it to one end-point, and
hold the multi-function button
pressed in for a period of three
seconds, i.e. until the servo
switches to the opposite end-point. It will now respond in
the desired direction. Servo reverse is not necessary for the
throttle function, as the system always controls a speed
controller the "right way round". The setting is stored per-
manently for each model.

7.10 Trims

The transmitter features digital trims for the three control
surface functions. The trims are used to fine-tune the cen-
tre position of the servos. When you adjust the trims, you
will hear a beep for every increment. For clarity you will
hear different double-beeps at the centre position and both
end-points. No trim is provided for the throttle function, as
modern speed controllers for electric power systems adjust
themselves automatically to the throttle stick's travel. The
trim setting is stored permanently for each model.

7.11 Dual Rates

In the case of a model aircraft it may be useful to reduce
the control surface travels at full movement of the sticks,
e.g. when the model is flying at high speed. In contrast, full
control surface travels are necessary when flying aerobat-
ics. The Dual Rate function allows the pilot to switch be-
tween full and reduced control surface travels while the
model is flying (Dual Rate does not affect the throttle func-
tion). Push down on one of
the two sticks to switch the
Dual Rate function on or off
for the control functions op-
erated by that stick.
An audible signal indicates
the current status: a brief beep indicates reduced servo
travel; a long beep normal servo travel.
