Overview

The Surpass Hobby BAT S4218 is an FPV brushless motor designed for high-efficiency multirotor power systems. It is available in 330KV or 560KV options, with 1PCS or 4PCS purchase selections to match single-motor replacements or full drone builds.

Key Features

  • Detachable design for easier cleaning and improved heat dissipation via a porous air outlet front cover structure
  • NMB bearings (Japan) for smooth, wear-resistant operation
  • 220°C high-temperature resistant multi-strand copper wire
  • 0.2 mm silicon steel sheet (Japan) for low heat generation and high efficiency
  • M6 shaft designed to fit most propellers; custom nuts help protect steel shaft threads
  • 48SH rotor NdFeB magnet tiles; lightweight high-strength hole-core steel shaft
