A brushless motor is an electric motor without brushes, which in comparison to the brushed motor is characterized by a higher efficiency, less wear and tear and the lower weight. ARTR models are prefabricated models that are ready for use almost out of the box. In contrast to RTR models, you need additional accessories before the model is ready for use. Active Vehicle Control (AVC) makes it easier for you to control your RC model. By means of automatic steering interventions, the model maintains the specified direction of travel regardless of external influences. This keeps it safely on track during heavy acceleration or braking and on surfaces with difficult grip conditions. Even bends are passed through true to track. The intensity of the support can be adjusted on the transmitter. In addition, the system optimises acceleration on loose surfaces, because, like a traction control system, it reduces the power when necessary, thus reducing wheel slip. Level of difficulty: Expert - You have experience in model making and have specific knowledge and tools. They are able to build their model from individual components themselves, adjust it correctly and operate it safely.
