JR's compact, lightweight RS-310 fits easily into most RC vehicles and works with all JR & Airtronics radios. It provides crystal-free convenience and unsurpassed noise rejection, thanks to it's sophisticated 3 Channel FM ABC&W circuitry. Forget about those crystals... Now you can just dial in the channel you want, anywhere from 61-90 on the 75Mhz ground frequency.

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

* Note that this is an FM-only receiver, check the rules of the competition you are attending to see if FM is legal in the robot weight class you are planning to enter (usually 60lb and under is fine).
