Adjusting The Shock Absorbers - Reely ROAD Firestar Notice D'emploi

b) Adjusting the shock absorbers
The spring elements of the all-wheel suspension of the chassis consist
of a coil spring each with an oil-pressure shock absorber in the centre.
The oil-pressure shock absorbers are fastened to the lower control arms
and the top of the shock tower on the differential housings. At the top, the
coil springs rest against a knurled nut on the outer tube of the shock
absorber and a spring seat on the bottom end of the piston rod.
Deflection travel of the piston rods is limited by silicone sleeves on the
lower part of the piston rods.
Turning the knurled nut upwards takes pressure off the spring. Turning it
downwards increases spring preload. Spring preload can thus be finely
adjusted to the ground and the way of driving.
• Low spring preload causes the chassis to sink down lower due to its
own weight.
• A harder setting lifts the chassis.
This means you have influence on lifting or lowering the chassis (setting
ground clearance). The suspension setting affects the model's ability to
"even out" road unevenness as well as the models behaviour in curves.
This is described as "oversteering" or "understeering" driving behaviour.
• Oversteering driving behaviour
The model "pulls" into the curve, the rear tends to swerve (too little traction on the rear axle or too much traction on the steered front axle).
As a counter measure, the suspension should be set softer at the rear (or harder at the front).
• Understeering driving behaviour
The model is difficult to steer around the curve, "pushes" outwards over the front wheels (too much traction of the rear axle or too little traction of the steered
front axle).
As a counter measure, the damping should be set harder at the rear (or softer at the front).
Oversteering or understeering driving behaviour can be the result of uneven cornering forces of front and rear axle due to incorrect camber settings.
As a basic setting, the front axle should be approx. 5 mm lower than the rear axle!
Check the effectiveness of the shock absorbers:
• Lift the model at the rear axle and then drop it.
• The model should not deflect to the end stop and only rebound once (without any additional swinging)!
• Test the shock absorbers at the front axle in the same way.
Setting spring preload
• Increasing spring preload: Turn the knurled nut on the external pipe of the shock absorber clockwise.
• Decreasing spring preload: Turn the knurled nut on the external pipe of the shock absorber anti-clockwise.
