This aluminum propeller joint is an RC-scale replacement part specified for the TAMIYA TT-02 chassis. Machined from aluminum with a black finish, the component is intended as a direct-fit alternative to common plastic couplings to improve durability and preserve drivetrain alignment in model use.
Fit and role: the joint installs at the propeller shaft coupling point on the TT-02 drivetrain, serving to maintain concentricity between driving components and reduce play that can affect handling and gearing response. As an upgrade part, it is intended to provide a more consistent mechanical interface during tuning and routine operation on 1/10 scale electric RC models.
Installation notes: the part is designed for drop-in replacement using the chassis' existing mounting points and hardware. Inspect mating surfaces and confirm fit before final assembly, then verify free rotation and alignment at low-speed spin before regular operation. Regular checks during maintenance cycles help preserve performance and detect wear.
Tuning considerations: using a stiffer metal coupling can change vibration characteristics and transfer loads differently compared with stock plastic pieces, so retest gear mesh and drivetrain runout after installation. For setup work focus on alignment and bearing condition to make the most of the joint's dimensional stability.
