This JR-DT305-RD accessory is an aluminium servo mount produced by JAZRIDER for the TAMIYA DT-03 chassis, intended as a scale RC replacement part to secure and align a standard 1/10 servo. The red anodized finish provides corrosion resistance appropriate for hobby use while keeping weight low compared with plastic mounts.
Compatibility is limited to the DT-03 chassis platform, so plan your installation around that model family. The part's role is mechanical: it locates the servo, maintains alignment with steering linkages, and gives a stable mounting surface that can reduce flex under load compared to 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 fasten the aluminium mount using the same screw pattern. Check servo horn alignment and horn-to-linkage geometry after installation to retain correct steering throw and centering. Small adjustments to linkage length or horn position may be needed to restore trim.
Tuning role: this mount is a platform-level upgrade that can improve steering consistency and feedback when testing different servo models or endpoint settings. Use it as part of setup work when dialing in steering responsiveness, endpoint travel, and servo centering for on-road or light off-road DT-03 setups.
