Futaba R203GF 3-Channel 2.4GHz S-FHSS Receiver
Futaba S-FHSS 2.4GHz receivers benefit from Futaba's patented Pre-Vision™ circuitry, which scans incoming data and corrects errors before they can become problems. They sync perfectly with Continuous Channel Shifting, handling hundreds of frequency changes per second with flawless precision. Plus, they all offer the Easy-Link™ advantage — the feature that allows the receiver to “learn” the transmitter module’s unique code with the push of a button and establish a unique, unbreakable bond between the two. 

Frequency Hopping Spread Spectrum (FHSS) technology minimizes interference from other 2.4GHz systems. Easy Link prevents unwanted signal conflicts by using a special, pre-assigned ID code. High-voltage  operation.
