OLL CENTER
The roll center is the theoretical point around which a vehicle tilts when driving
curves.
The roll center results from the chassis geometry.
If you draw a line each parallel to the top (a) and bottom (b) transverse link on one
side, these intersect on the opposite side. If you join this point of intersection (c) with
the wheel contact spot, the roll center is located on the intersection of this straight line
(d) with the center axis of the model (x).
In case of a low roll center, the leverage effect of the pint of gravity is high, and the vehicle tends to tilt stronger
around the roll axis in curves.
You can change the roll center of an axis by shifting the top transverse link of the front and rear axis to other
steering points and therefore change the angle between the top and bottom transverse link.
- A low roll center results in increased tire adhesion and better cornering force at the end of the curve.
- A high roll center reduces the heeling and the vehicle becomes more agile.
Changes must be performed evenly on both sides!
A change of the roll center also has an effect on other vehicle settings!

AIL SAFE
In order to enter the fail-safe Set-Up mode, you must keep the Set button pressed down before and while your switch on the transmitter and the
receiver.
The blinking red LED indicates that now a fail-safe setting for the servo can be selected in case of a malfunction of the radio contact.
- Place the connected servo via the remote control in the desired position and
- actuate the latter by pressing the set button once more. The selected position is now saved.
In case of a malfunction of the radio contact, the servo moves in the selected position.
U
NDERVOLTAGE PROTECTION
The blinking green LED indicates that now a setting of the undervoltage protection for the rechargeable battery of the receiver can be
selected.
When the minimum voltage is exceeded, the servo moves into the fail-safe position.
The Set button must not be pressed. The former setting is maintained.
Press the Set button once:
Press the Set button twice:
Press the Set button thrice:
As long as the fail-safe gets valid input signals, the output of the fail-safe follows this input.
In case of a fault in the radio transmission, the output goes into the selected fail-safe mode. The fail-safe mode is reversible, i.e. as soon as a radio
contact is restored, the model reacts normally again to the control commands.
If an undervoltage protection was selected (setting 1 or 2) and if the minimum voltage of the rechargeable battery of the receiver was exceeded, the
output of the fail-safe goes into the fail-safe mode permanently.
