Firma 12T Rebuildable 550 3 Pole (SPMXSM6123)

The Spektrum Firma 12T Rebuildable 550 Brushed Motor is a budget-friendly upgrade for brushed ESC-equipped 1/10-scale RC vehicles, delivering stronger torque and improved efficiency. Built around a 550-size can with a 12-turn, 3-pole design, it suits on-road, off-road, and crawler setups, offering solid performance with a fully rebuildable construction for easy maintenance.

Designed to fit most 1/10-scale vehicles that run brushed power, this motor features adjustable timing from 0 to 20 degrees for precise tuning and supports clockwise and counterclockwise rotation. Pre-shaped curved-face brushes reduce break-in time, and wires with 4 mm bullet connectors are installed so soldering isn’t required. The rebuildable design provides easy access to the commutator with replaceable brushes, springs, and bearings, while metal shielded ball bearings help extend life. Available in 12T, 14T, and 35T variants to match different torque and speed needs.
