 Product Description

The X12L Short Course 550 is based on the revolutionary X12 brushless modified motor. It is exactly tailored for the demands of the popular Short Course trucks. With a ”L“ for Large now a new, longer version of the worldwide successful Vector X12 is available. The brushless motor is equipped with the fully adjustable and replaceable PreciSensorTM system: this new, precise sensor positioning delivers a power never seen before, highest torque, perfect throttle response and outstanding efficiency. 
The motor is unlike any other brushless motor. The X12L Short Course 550 is constructed of two main parts, using only four screws.
