g) "SUB-TR" function: adjusting the servo centre
When installing the servos, the model manufacturer usually describes the exact central position for the servo levers.
However, the cogs on the servo lever may not always allow the exact positioning of the servo lever if the operating
levers and the corresponding trim are in the central positionon the transmitter.
In this case, the trimming would not be centred when driving straight ahead. This limits the trimming travel, and the full
trimming travel cannot be used on both sides. This drawback can be eliminated using the servo centre adjustment.
In addition, the trimming indicator is thus exactly centred when driving straight ahead, which allows for easier
estimation of straight-ahead driving and possibly the necessary trimming.
Proceed as follows:
• If you press the knob (14) briefly, the
MODEL
function will be greyed out.
•
Turn the knob (14) to the left or right until the
SUB-TR
function is greyed out
on the display, as shown in the right figure.
• If you press the knob (14) briefly, the channel number 1 will flash at the bottom
of the display.
"ST" (= "steering") also flashes for channel 1.
"TH" (= "throttle") also flashes for channel 2.
"AUX" (= "auxiliary" = auxiliary channels) also flashes for channels 3 – 6.
• If you press the knob (14) briefly, the setting value for the trimming travel will flash at the bottom right of the display.
•
You can change the setting by turning the knob (14) to the left or right.
The middle position can be changed to the left/right, front/back and up/down depending on the channel.
These directions typically depend on the specific model and the servo function. However, the respective
letters on the display are used for the centre adjustment.
Channels 1 + 5 + 6: (L = "Left", R = "Right")
L120....R00.....R120 = left 120.....middle.....right 120
Channel 2: (B = "Back", F = "Front")
B120.....F00.....F120 = back 120.....middle.....front 120
Channels 3 + 4: (D = "Down", U = "Up")
D120....U00.....U120 = down 120.....middle.....up 120
• If you press the knob (14) briefly, the setting value for the servo middle position will stop flashing. The current setting
is saved.
If no indication is flashing, you can select another function to be changed by turning the knob (14).
To exit the setup menu instead, briefly press the "BACK" button (13). The transmitter will emit a short beep,
and the greyed out field will disappear from functions at the top of the display. The transmitter is back in its
normal mode.
