Details

The T-Motor brushless motor comes fitted with a two-blade propeller for a clean, ready-to-mount setup.

T-Motor propeller dimensions and hub profile help confirm fit and clearance during setup.

T-Motor thrust test curves help compare RPM, torque, current draw, efficiency, and power across the throttle range.

The T-Motor A12-14S modular propulsion system includes the motor-and-prop assembly and a parts bag with mounting plate, screws, and a strap.
