Based on the popular R700 that topped the performance levels of all other FM receivers tested by a well-known independent lab, JR SPORT’s new 6-channel RS600 is a proven, shift-selectable receiver engineered to operate with all major transmitter brands, including Futaba and HiTec. JR has a unique signal processing system called ABC&W. ABC&W stands for Automatic Blocking Circuit with Window. ABC&W systems have distinct advantages over single or dual conversion receivers. ABC&W systems create a very small electronic window that looks for the specific frequency that the receivers crystal is on. Any signal that is off spec for this window is rejected, and then the allowed signal is cleaned up, amplified, and re-routed through the window many, many times till all that is left is the pure signal on the channel that is coming from your transmitter and then sent on to the servos. This all takes place without any noticeable delay of response from your stick movement to the servo. This technology is the reason that JR can produce single conversion receivers that have fewer components and weigh less than other single and dual conversion receivers without the worry about outside interference.
Applications: Any aircraft up to 6 channels
Size: .98" X 1.84" X 0.61"

Boasting excellent range among receivers in its class, this is the micro that was used by 5 of the top 6 fliers in the “First Annual Indoor TOC,” held in conjunction with the 2004 Toledo event. Purchase it in either positive (JR and Airtronics) or negative (Futaba and HiTec-JSP30615) shift. JR has a unique signal processing system called ABC&W.
