The Reedy Sonic 540.DR Drag Racing Modified Brushless Motors bring power and efficiency to drag racing. Even though these motors resemble the more common 540-M4 Reedy motors the 540.DR offers significant internal changes. Featuring an updated stator with thicker laminations and using a unique material produces power specialized for the drag strip. A balanced, high-strength 13.5mm rotor spinning on precision ball bearings gives consistent power run after run. Encasing all of this is a CNC machined lightweight motor can. The Sonic 540.DR offers the quality, reliability and high performance you expect from Reedy electronics.
