Reely 1:8 GP Buggy Ultra Sonic 4WD RtR Notice D'emploi page 65

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 camber.
As a basic setting the front axle should be approx.. 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 knurled nuts on the outer tube of the shock absorber clockwise.
• Decreasing the spring preload Turn the knurled nuts on the outer tube of the shock absorber counter-clockwise.
Tuning
By selecting the right shock absorber oil, you can influence the shock absorbing characteristics. The oil normally used
in the shock absorbers is perfectly suited for most applications.
• On mainly smooth ground, we recommend more viscous oil (high viscosity).
• On open terrain, however, you should use a less viscous oil (low viscosity).
Do not use any standard engine oil. We generally recommend using pure silicon shock absorber oil only. To
further optimize the damper characteristics we offer silicon oil for the shock absorbers in different viscosities
in our accessories.
Changing of shock absorbers
The front and rear shock absorbers have seven (front) additional attachment points on the top and five on the rear in
addition to the normally used one and one additional steering point each at the transverse control arm.
• Shifting on the top transverse control arm to a steeper clearance angle reduces progressivity. The vertical relative
movement of the chassis is transmitted more direct to the spring suspension, the shock absorber effect kicks in
immediately, meaning the spring suspension is harder when engaged even slightly. At the same time the vehicle is
brought in a higher position.
• Moving the shock absorbers to a flatter clearance angle increases progressivity. In case of a flat clearance angle, the
chassis has to deflect deeper so that the shock absorbers kick in, meaning the shock absorbers initially respond
softly and then increasingly harder. The vehicle is lowered.
