Damping
To further optimize the damper characteristics we offer silicon oil for the shock absorbers in different viscosities in our
accessories. Our product range also includes tuning springs of various hardness.

Function of the Two-Speed Transmission
Two pinions with a different number of teeth are tightly screwed onto the clutch bell. The two main pinions on the
centrifugal clutch are connected with each other via a one-way bearing. The shift point depends on the revolutions.
In the first driving stage, the engine revolution speed is transmitted by the smaller pinion on the clutch bell to the larger
cogwheel on the power train. The gearwheel for the second gear travels along. At high speeds the centrifugal force
causes the lever of the centrifugal clutch to be pulled outward towards a spring resistance and the attachment on the
toothed wheel grips into the second rate of speed. The engine speed is now transmitted via the larger pinion of the
clutch bell to the smaller toothed wheel in the drive section, the toothed wheel in the first rate of speed is running via
the one-way bearing. The spring resistance of the centrifugal clutch, and with it the switch point, can be adjusted with
a headless screw.
• Put down the model so that the wheels can turn freely.
• Turn the main pinions on the two-speed transmission until
the clearance in the cover of the two-speed transmission
is visible. You can access the headless screw from the
left.
• Turning in the screw: The spring preload is increased.
Higher revolutions are needed so that the attachment to
grips. The transmission switches later.
• Unscrewing the screw: The spring preload is lowered.
Lower revolutions are needed so that the attachment grips.
The transmission switches earlier.
If you are a beginner and are facing problems with the driving speed, we recommend that you postpone the
switch point until the model does not switch into second gear at all.
