Details

The T-Motor brushless motor comes pre-fitted with a two-blade propeller for quick installation on a drone frame.

T-Motor mounting dimensions and hole spacing help confirm frame and propeller fit before installation.

T-Motor performance curves plot torque, RPM, current, efficiency, and power against thrust to help compare operating points.

The modular propulsion system includes a motor with folding propeller plus a parts bag with mounting plate, hardware, and a strap.
