Tekin T8 Gen2 4038 1:8 BL Motor 1550kv Sensored/Sensorless 40x77mm

The Tekin T8 Gen2 4038 1550kV is a competition-grade 1/8 scale truggy brushless motor that delivers smooth, controllable power with sensored precision or sensorless versatility. Engineered within the Redline family for large-scale high-performance racing, it’s designed to convert battery energy into forward drive efficiently and reliably. For a cohesive power system solution, Tekin recommends pairing the T8 Gen2 with the Tekin RX8 Electronic Speed Control.

With a 40mm diameter can (42mm including cooling fins) and 77mm length, plus a 5mm shaft with flat, this TT2368 variant follows common 4038-class dimensions used in 1/8 truggy racing. The 1550kV wind offers a balanced torque-to-speed profile aimed at pro-level control and on-track consistency.

A ribbed heatsink can machined from 6061‑T6 billet aluminium helps manage temperatures during long mains, while a neodymium sintered magnet and precision engineering focus on maximum energy conversion. High current solder tabs simplify robust, low-resistance connections, and the rebuildable design supports long-term serviceability. The dual-plug sensor wire harness provides flexible installation routing, and you can run sensored for ultimate throttle feel or switch to sensorless operation if preferred.
