LRP Vector X12L SC 550 5.0T motor
The LRP X12L Short Course 550-size motor is based on the well-known X12 brushless motor series by LRP. The longer “L” version is specially designed for the use in the somewhat heavier 1/10 scale 4WD Short Course trucks and sports adjustable timing, a sintered magnet 13mm rotor and speedy 5.0T winding that adds to the already existing 4.5T and 5.5T variants.
