Tamiya 15205 - 1.4mm Hollow Propeller Shaft, Lightweight S.1/TZ Upgrade  [15205]

Lightweight propeller shaft for S.1 and TZ Mini 4WDs

The Tamiya 15205 1.4mm Hollow Propeller Shaft is built for the S.1 and TZ Mini 4WD chassis. Its hollow construction reduces rotating mass while maintaining structural strength, giving racers a simple, effective way to cut weight in the drivetrain. Suitable for hobbyists focused on tightening lap times without sacrificing reliability.

Compatibility and performance role

Made as a direct swap for the standard solid shaft on S.1 and TZ frames, this hollow shaft lowers overall drivetrain weight to improve acceleration and transient response. It is intended for racers who want incremental gains in handling and corner exit speed through reduced inertia.

Track use and handling benefits

On tighter technic-style tracks the lighter shaft helps the car respond quicker to throttle changes and steering inputs. While not a single fix for every setup, it pairs well with balanced gearing and clean bearings to deliver noticeable improvements in lap consistency.
