Overview
The Futaba 4GRS is a 4-channel digital proportional 2.4GHz radio system built for surface models such as RC cars, trucks and crawlers. It pairs the T4GRS pistol-grip transmitter with the compact R304SB receiver for a complete, ready-to-bind control package.
The transmitter supports T-FHSS, S-FHSS and FHSS protocols, stores up to 40 models and adds car-specific mixing such as brake mixing, 4WS and dual ESC control, making it a strong choice for bashers and racers alike.
