Overview
Unique to JR Propo's radios is the company's patented ABC&W technology, or Automatic Blocking Circuit with Window. Simply put, this system rapidly reroutes incoming signals through a series of ever-smaller electronic "windows," effectively blocking out spurious signals which cause radio "glitching". Any signal that does get through the system is filtered before being sent to the servos all without noticeable lag or delay. If the signal is unable to be processed, it is rejected, again without noticeable reaction.
