These components are standardized, hexagonal-shaped mounting interfaces on radio-controlled vehicles, measuring 17 millimeters across the flats of the hexagon. They are designed to securely attach the rolling elements to the axles of larger-scale RC cars, typically 1/8 scale buggies, truggies, and monster trucks. A corresponding hexagonal recess is integrated into the wheel’s hub, ensuring positive engagement and efficient power transfer.
The adoption of this specification brings significant advantages. It provides a robust and reliable connection, capable of withstanding the high torque and stresses associated with off-road RC racing and bashing. Their widespread use ensures interchangeability across different manufacturers and models, simplifying parts selection and upgrades. Furthermore, this standard represents an evolution from smaller, less durable mounting systems, reflecting the increasing power and performance demands of modern RC vehicles.
