AVAILABLE MODES and PROGRAMMING THE MODES:
The SPHERE features 4 different modes, which enable you to adjust motor type and application, motor power/
driving feel, initial-brake and automatic brake to match YOUR special requirements precisely.

to select between the different

MODE.4 (automatic brake):
llows you to set a slight braking action, which is applied in the neutral range.
This enables you to simulate the feel of a brushed motor and also hold the throttle on longer when entering a
turn. Your car also has more front traction with this setting.

INITIAL-/AUTOMATIC-BRAKE DEPEN
Only this unique feature will give you perfect brake-control. By not allowing lower initial-brake values then auto-
matic-brake values, it ensures that the brake doesn‘t become less when you manually brake on the transmitter.
This means, for example, if you have set automatic-brake on value 2 that you can not adjust value 0 or 1 on
initial-brake (the set automatic-brake value becomes the minimum initial-brake value!).
LRP speed-controls are supplied factory-adjusted. The defaults are the grey-shaded/bold areas in the Value
columns above. If you loose track of the modes during the set-up procedure, you can reset the speed-control
to the LRP works default settings. With the transmitter switched on, hold the SET button pressed while you
switch on the speed-control. This action returns the unit to the LRP works default settings.
CHANGING MODE SETTINGS WITHOUT THE TRANSMITTER:
At race events you usually do not have access to your transmitter. In this situation it is possible to adjust the
MODE settings without the transmitter signal. All you have to do is disconnect the receiver lead from the recei-
ver and connect the drive battery. You can now change the MODE settings as described in this chapter.
SENSORED BRUSHLESS TECHNOLOGY:
The SPHERE speed-control uses the sensored brushless technology to communicate with the brushless motor.
This allows the SPHERE to obtain perfect knowledge of the brushless motor’s magnet position. This means
perfect motor control at high and low RPM‘s, as well as perfect brake control. The sensored brushless motor
feels just as smooth to drive as the brushed motor!
MULTI-PROTECTION SYSTEM, 4-way Protection
This unique monitoring software is the perfect protection for the SPHERE speed-control against short-circuits
(motor), overload and overheating. If your speed-control is ever faced with overload, the motor function is
switched off for protection and the SET LED will fl ash to indicate the overload, although the steering function is
maintained. Wait a few minutes to allow the speed-control to cool down.
Should you accidentally select one of the brushless motor modes while a brushed motor is connected to the
speed-control, or vice versa, the SPHERE will warn you of this error by turning on the red SET LED and alterna-
tively fl ashing red/green on the MODE LED. If the speed-control switches off frequently, either the motor used
is too strong, the motor pinion is too big or you are using full brake too often. You can improve this by using the
supplied heatsink or by obtaining the optional LRP fan (#82500).
