Tamiya TB-03 7075 Aluminium Motor Mount by 3Racing TB03-15  [TB03-15]

Aluminium motor mount for TB-03

The 3Racing TB03-15 is a 7075 aluminium motor mount designed for the Tamiya TB-03 RC chassis. Built as a direct hop-up replacement, the part focuses on rigid motor positioning and repeatable alignment to support consistent pinion-to-spur mesh and easier tuning of gear engagement.

As an RC-scale accessory, this motor mount replaces the stock plastic unit and is intended to use existing mounting points and hardware on the TB-03. The 7075 aluminium offers higher stiffness than typical stock materials, reducing flex under load and helping maintain gear mesh during acceleration and braking transitions.

Installation is straightforward for a hobbyist with basic tools: remove the original motor mount, transfer the motor and applicable spacers or shims, fit the 7075 mount in place, and secure with the chassis screws. After mounting, verify motor height and backlash across the spur and pinion, then make minor adjustments for optimal engagement and minimal noise.

Use this mount to reduce movement at the motor interface, gain a firmer mesh setup, and streamline gear tuning on TB-03 cars that retain stock mounting geometry.
