b) Setting the shock absorbers
The spring elements of the all-wheel suspension of the chassis consist each of a coil spring (1) in whose
center an oil dampened suspension () is located.
The oil-dampened shock absorbers are mounted on the lower transverse links and at the top on the
damper plate on the differential housings. On the top, the coil springs rest against a screw ring (3) on
the outer tube of the shock absorber and a plate on the bottom end of the piston rod. Turning the screw
ring towards the top relieves the spring.
Turning it downward increases the spring preload.
The spring preload can thus be finely adjusted according to surface and manner of driving. A low spring
preload makes the chassis sink deeper under its own weight, while a harder setting lifts the chassis
up. In this way, a certain higher or lower position of the chassis can be achieved (setting ground
clearance).
The setting of the suspension influences not only the ability of the model to “even out” road unevenness, but also the behavior in bends.
This driving behavior is called to “oversteer” or to “understeer”.
Understeering driving behavior:
The model is difficult to steer around the bend, “pushes” the front wheels outwards (too much traction of the
rear axle or too little traction of the steered front axle.
As a counter measure the suspension should be set harder at the rear (or softer at the front).
Over-steering driving behavior
The model “pulls” in the bend, the rear tends to swerve (too little traction on the rear axle or too much traction at the steered front axle).
As a counter measure the suspension should be set softer at the rear (or harder at the front).
Over-steering or under-steering driving behaviour can be the result of uneven cornering powers of front and rear axle due to incorrect setting of the cam-
ber.
As a basic setting, the front axle should be set approximately 5 mm lower than the rear axle!
Check the impact of the shock absorbers:
Lift the model at the rear axle and drop it.
The model should not deflect until lock and only top out once without any reverberation!
Test the shock absorbers of the front axle in the same way.
Setting the spring preload
Increasing the spring preload
Turn the screw ring on the outer tube of the shock absorber clockwise.
Decreasing the spring preload
Turn the screw ring on the outer tube of the shock absorber anticlockwise.
Tuning
The oil used in the shock absorbers is perfectly suited for most applications. By selecting the right shock absorber oil, you can influence the shock absorbing
characteristics.
On generally even ground, we recommend using a more viscous oil (high viscosity), on rough terrain, however, you should use a low-viscosity oil.
Do not use any engine oil. We generally recommend using pure silicon shock absorber oil only.
To further optimize the damper characteristics, we offer, in our accessories, silicon oil for the shock absorbers in different viscosities!
