If you run a sensored motor you will need an ESC with sensored capability to run best. Some ESCs can only run sensored, others only sensorless, while in my opinion the best ESCs do both. All of the common brands should work just fine with the Reedy motor as long as they run sensored motors. I would recommend the Hobbywing Xerun or Tekin RS. In my opinion they both work equally well. Hobbywing offers excellent prices while Tekin offers some of the best customer service in the business and years of racing experience.
