Injora Aluminum INJS15 Coreless Servo with Mount & Horn Set for TRX-4M (Waterproof)

The INJORA INJS15 delivers powerful 15kg torque, fast coreless‑motor response, and smooth, consistent steering performance for the TRX4M.

With the included aluminum mount and 25T horn, it installs easily and provides a strong, reliable steering solution for heavier 1/18 builds.
