8. Set-Up
Transverse Stabilisers
To reduce body roll (curl) of the vehicle when going through bends, the model is equipped with a
transverse stabiliser at the rear. A transverse stabiliser is made of a u-shaped curved spring steel
wire, which is at both ends connected with one of the lower transverse arms via ball-shaped heads.
For this reason, two steering points for the ball-shaped heads are provided. In the centre, the wire
bracket is mounted to rotate on the differential housing. The boreholes for the mounting are also
provided. When one wheel is deflected, the other wheel is then also deflected via the bracket.
The transverse stabiliser also supports the effect of the oil-dampened shock absorber when the
wheel is rebounding, since the restoring force of the wire bracket supports the rebounding of the
shock absorber (against the friction in the piston). In this way, the wheel remains in contact with
the ground in every situation.
Optionally an anti-roll bar can be installed at the front axis.
Changing of the roll centre
The roll center is the theoretical point around which a vehicle tilts when driving curves.
The roll center results from the chassis geometry.
If you draw a line each parallel to the top (a) and bottom (b) transverse link on one
side, these intersect on the opposite side. If you join this point of intersection (c) with
the wheel contact spot, the roll center is located on the intersection of this straight
line (d) with the center axis of the model (x). In case of a low roll center, the leverage
effect of the pint of gravity is high, and the vehicle tends to tilt stronger around the
roll axis in curves.
You can change the roll center of an axis by shifting the top transverse link of
the front and rear axis to other steering points and therefore change the angle
between the top and bottom transverse link.
- A low roll center results in increased tire adhesion and better cornering force at
the end of the curve.
- A high roll center reduces the heeling and the vehicle becomes more agile.
Changes must be performed evenly on both sides!
A change of the roll center also has an effect on other vehicle set-
tings!
Installation of fail-safe electronics
Electronic switching which moves the connected servo into a free to select position in case of an interruption of the
radio contact e.g. if the range is exceeded or in case of a transmission fault or in case of low voltage of the receiver
battery. The fail-safe function can be integrated in the receiver and can as well be inserted between the receiver and
the servo as additional constructional element
In order to enter the fail-safe Set-Up mode, you must keep the Set button pressed down before and while your switch
on the transmitter and the receiver. The blinking red LED indicates that now a fail-safe setting for the servo can be
selected in case of a malfunction of the radio contact.
- Place the connected servo via the remote control in the desired position and
- actuate the latter by pressing the set button once more. The selected position is now saved.
In case of a malfunction of the radio contact, the servo moves in the selected position.
Undervoltage protection
The blinking green LED indicates that now a setting of the undervoltage protection for the rechargeable battery of the receiver can be selected.
When the minimum voltage is exceeded, the servo moves into the fail-safe position.
The Set button must not be pressed.
-
- Press the Set button once:
Press the Set button twice:
-
- Press the Set button thrice:
As long as the fail-safe gets valid input signals, the output of the fail-safe follows this input.
In case of a fault in the radio transmission, the output goes into the selected fail-safe mode. The fail-safe mode is reversible, i.e. as soon as a radio contact
is restored, the model reacts normally again to the control commands. If an undervoltage protection was selected (setting 1 or ) and if the minimum
voltage of the rechargeable battery of the receiver was exceeded, the output of the fail-safe goes into the fail-safe mode permanently.
