For TB-04 enthusiasts looking to lengthen service intervals and sharpen drive feel, the Tamiya 54585 aluminium pilot shafts are a sensible swap. They replace the standard kit shafts with parts that balance low mass and good toughness, helping the motor transmit torque more reliably.
Aluminium provides a favourable trade off between weight and strength, useful where cutting rotating weight matters. Upgrading to aluminium pilot shafts often yields steadier acceleration and less drivetrain strain during sustained runs.
The Tamiya 54585 shafts are designed to drop into TB-04 chassis layouts without extra modification, making the upgrade straightforward for model builders.
