Details

The BAT S2004 and S2006 brushless motors support 3-inch, 3.5-inch, and 4-inch FPV drone builds.

NMB bearings, high-temperature copper windings, and silicon steel stators support efficient motor operation across the available KV options.

A 1.5 mm shaft, 5 mm propeller mounting hole, and 12 mm frame mounting hole support compatibility with varied propellers and frames.

The detachable construction simplifies motor cleaning, while front-cover air outlets help dissipate heat during operation.

A 48SH neodymium iron boron rotor and lightweight, high-strength steel shaft contribute to the motor's compact construction.

S2004 specifications cover 1800KV and 3000KV configurations, with dimensions and thrust-test data provided for selection.

S2006 specifications cover 2000KV and 2500KV configurations, with detailed dimensions and thrust-test results for build planning.
