m) "CRAWL" function: Crawler mode
Here you can set the steering mode for a crawler vehicle. This is for a vehicle built specifically for manoeuvring tests.
For this purpose, crawler vehicles usually have steerable front and rear axles. The steering of the front and rear axles
is controlled via a separate steering servo.
This function enables you to switch between front axle steering, rear axle steering, reverse steering or co-steering of
the two axles.
Channel 3 of the receiver is always used to control a steering servo of the rear axle. Channel 1 typically
serves to control the steering servo of the front axle.
In addition, both steering servos can be controlled simultaneously using the steering wheel (4).
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
CRAWL
function is greyed out,
as shown in the right figure.
• If you press the knob (14) briefly, "OFF" will flash at the bottom of the display.
•
You can select one of the four steering functions by turning the knob (14) to
the left or right. When "OFF" flashes, the crawler mode is switched off.
A = Only front axle is steered
B = Only rear axle is steered
C = Front and rear axles are steered in the same direction (thus the vehicle can move diagonally)
D = Front and rear axles are steered in opposite directions (thus a smaller turning circle is achieved)
• If you press the knob (14) briefly, the indication will stop flashing. The current crawler mode setting will be saved.
If desired, you can now 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.
When the crawler mode is switched on, the indication (A, B, C and D; see above) will remain on the display
(even if you exit the setup menu). When steering, you always have an overview of the currently active
steering function.
