"The 4GRS is an AWESOME radio! The system is very easy to use. The dial – properly placed above the throttle – clicks like a needle valve on an engine, which is a huge plus. The 4GRS also supports FHSS, S-FHSS and T-FHSS protocols, providing boaters with the reliability and security they can trust. The 4GRS never lets go of your boat, even if in long-range or upside-down conditions!"

Everyone – from hard-core crawlers and scalers to competition boaters and racers – who demands the most from their radios will find that the 2-stick 4GRS meets and exceeds every requirement. Telemetry functions relay critical information to a graphic LCD screen. Extreme off-roaders will appreciate the dual ESC mixing for locking diffs, four-wheel steering and independent brake mixing. And the jog dial/button layout makes navigating menus quick and easy.
