The Firebolt 12T, 550-size motor is the standard Motor in the Monster King RTR! The extra-large size means you'll get extra torque for excellent acceleration and "pop" over jumps.

Features standard motor mounting screw locations for an easy drop-in fit for most 1/10th scale RC kits.

Note: if replacing a standard motor in most RTR vehicles, you will need to alter the spur gear and pinion gear to match the extra power and RPM of this motor. Check your speed controller to make sure it can work properly with brushed type motors with 12 turns or less.
