• Function #9, green LED, one long and four short flashes: Timing
Generally, higher values for timing increase the engine speed. Torque, however, decreases and power consumption
increases (lower driving time, engine and controller may overheat). The manufacturer has already chosen the best
settings for the engine built into the vehicle. It should only be changed by experienced model sportsmen.
Settable values are 0.00°, 3.75°, 7.50°, 11.25°, 15.00°, 18.75°, 22.50° and 26.25°.
• Function #10, green LED, 2 long flashes: Overheating protection
As preset by the manufacturer, the overheating protection of the speed controller activates if a temperature of
approx. 95°C is measured for longer than 5 seconds. In this case the motor is switched off and the green LED
flashes.
For safety reasons, we recommend that you always activate the overheating protection.
When it is switched off, the speed controller unit can be destroyed by overheating, and your guarantee will
be void!
• Function #11, green LED, 2 long and 1 short flashes: Rotational direction of the motor
Depending on the vehicle gearbox, the rotational direction of the motor can be changed.
This has the same effect as swapping two of the three cables between the speed controller and the motor. This will
also reverse the rotational direction of a brushless motor.
This setting was already made according to the vehicle in the factory and should not be changed.
• Function #12, green LED, two long and 2 short flashes: Number of LiPo cells
The two battery connections of the speed controller are switched in series. Two driving batteries of the same build
and the same charging state must be connected.
The vehicle must only be used with two 2-cell LiPo rechargeable batteries (nominal voltage 7.4V each) or
two 6-cell NiCd-/NiMH rechargeable batteries (nominal voltage 7.2V each). When driving batteries with
more cells are used, the vehicle drive will be overloaded; cogwheels, joints and drive axles will be dam-
aged, and the guarantee/warranty will be void!
Do not mix the two types of rechargeable batteries - use either two LiPo driving batteries or two NiMH
driving batteries.
The driving batteries must always have the same capacity and discharge rate. Therefore, they must have
the same type and manufacturer.
Only connect fully charged driving batteries to the speed controller. Otherwise, a wrong number of cells
may be recognised in the "Auto" setting, and the undervoltage-protection may not work properly. This may
lead to deep discharging of the batteries!
Therefore, we recommend changing the basic setting "Auto" to the setting "4 cells" (also when using two 6-
cell NiMH driving batteries!). This ensures that the undervoltage protection works properly even if no fully
charged driving batteries are connected.
