The JR-DT305-RD is an aluminium servo mount produced for the TAMIYA DT-03 chassis, intended as a scale replacement part to secure and align a standard 1/10 servo. The red anodized finish helps resist corrosion and keeps weight lower than equivalent plastic mounts.
Compatibility is focused on the DT-03 chassis platform, so plan your installation for that model family. The mount locates the servo, keeps alignment with steering linkages, and provides a stable mounting surface to reduce flex compared with stock plastic parts.
Installation notes: remove the original plastic mount using the vehicle's existing mounting points, transfer any required bushings or spacers if present, then attach the aluminium mount using the same screw pattern. After fitting, check servo horn alignment and linkage geometry and make small adjustments to restore trim if needed.
Tuning role: this mount acts as a platform-level upgrade to enhance steering consistency and feedback when evaluating different servo models or endpoint settings. Include it when setting steering responsiveness, travel and centring on DT-03 setups.
