6. 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 (a). In the cen-
tre, the wire bracket is mounted to rotate on the differential housing. The boreholes for the moun-
ting are also provided (b). 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 reboun-
ding of the shock absorber (against the friction in the piston).
In this way, the wheel remains in contact with the ground in every situation.
Damping
To further optimize the damper characteristics, we offer, in our accessories, silicon oil for the shock absorbers in different viscosities!
Our product range also includes tuning springs of various hardness.
Roll center
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 settings!
