Due to the LRP exclusive A.I. Automatic Technology, there is no need for a manual setup of the
speed control by pushbuttons or potentiometers. All you need to do is simply plug in the speed
control and you’re ready to go. The speed control “learns” the neutral, full-speed forward and
full-speed reverse point of the radio system while the car is running. This way, the speed control
has the optimized setup for every run - automaticly. Incorrect or unperfect setups are a thing of
the past with the LRP Quantum Micro Reverse A.I. speed control.
Digital protection against radio interference, “The guardian angel“. The safety electronic can
detect reception of a “false” or incomplete radio signal, e.g due to a low transmitter battery or
environmental radio interference which reach the model, or if the model is out of the transmitter
range. For protection against damage, the speed control switches to the neutral position and the
LRP’s tip: The model will remain in a standstill, even if you connect the drive battery to the speed
control fi rst and then switch on the transmitter! Provides perfect protection against mistakes
commonly made by beginners.
The LRP Quantum Micro Reverse A.I. digital speed control has no reverse time limit.
This unique monitoring software is the perfect protection for the LRP Quantum Micro Reverse
A.I. digital speed controls against short-circuits (motor), overload and overheating. If your speed
control is ever faced with overload, the motor function is switched off for protection, although
the steering function is maintained.
Wait a few minutes to allow the speed control to cool down.
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 if you make additional cooling

After wiring up the speed control, the LRP Quantum Micro Reverse A.I. is ready to operate.
No setup is required. The speed control „learns“ the neutral, full-speed forward and full-speed
reverse points while the car is running. Please note: Before you plug in the drive battery, set the
transmitter to neutral position and then start the model in the forward direction.
• If you have made a mistake so far, don’t worry: Unplug the battery for about 10 seconds and
• After the run, fi rst unplug the battery and then switch off the transmitter. When you start
again, fi rst switch on the transmitter and then plug in the battery.
