D) Setting The Track; Advanced Tuning - Reely Firestar Bedienungsanleitung

d) Setting the track

The track designates the position of the wheel level to the driving direction.
When driving, the tyres are pushed apart at the front because of the
rolling friction and are therefore no longer exactly parallel to the driving
direction. To compensate this, the tyres can be adjusted (when the vehicle
is not moving) so that they point slightly inwards. This toe-in improves
the cornering of the tyre and thus results in a more direct control of the
steering.
If a softer steering response is desired, the toe-out can be adjusted
accordingly, i.e. the wheels of the vehicle point outward (when it is not
moving).
For a rough adjustment of the track, the outer steering links can be
screwed to two additional attachment points on the steering plate. This
also changes the Ackermann steer angle. Straining screws (see figure
below, pos. "a") for separate alignment of the front wheels are located in
the right and left steering link between the steering lever and the steering
plate.
The toe-in of the front wheels must not exceed 4°!
Toe-in (a):
Turning the straining screws (1) towards the front lengthens the outer steering link, the wheel is pushed outwards
via the steering knuckle arm at the back. With this setting, the wheels wear off a lot faster on the inside.
Toe-out (b):
Turning the straining screws backward shortens the outer steering link; the wheel is pulled inwards via the steering
knuckle arm at the back. With this setting, the wheels wear out a lot faster on the outside.
e) Advanced tuning
Setting the differential
The model's rear differential is filled with grease. The viscosity of the grease blocks the differential, which is suitable for most terrains and conditions.
By exchanging the grease with high-viscosity silicone differential oil, the blocking effect can be modified. The higher the viscosity, the higher is the blocking
effect.
• If the model swerves in curves under load, you can loosen the differential.
• If the model understeers under load, block the differential.
You can select between silicone oil with a viscosity of 1000 (small blocking effect) to 50000 (high blocking effect).
Caution! Only experienced model pilots who know their models and have adequate technical skills for demounting and disassembling the differentials
should exchange the transmission grease.
Damping
To further optimize the damping characteristics, we offer silicon oil for the shock absorbers in different viscosities as an accessory. Our product range also
includes tuning springs of various hardness values.
Ackermann effect
To adjust the progressivity of the steering angle of the wheel inside the
curve (Ackermann steer angle), the steering links can be reset to other
steering points both at the steering arms and at the steering plate.
