This spur gear adaptor is an RC-scale replacement part designed specifically around the Auper D6 reference in the product name. It provides a dedicated interface between the spur gear and the drive assembly on that platform, offering a straightforward way to adjust alignment without altering the primary gearbox components.
Keep the red adaptor as a marked spare to speed repairs and reduce setup confusion. Its slim profile is intended to fit without raising the gearbox stack significantly.
Always clean mating surfaces and confirm mesh after installation. This component is supplied as a tuning and maintenance accessory for the Auper D6 platform and should be used only in RC model applications.
