Product overview
The RadioLink RC4GS V3 is a five-channel surface radio transmitter for cars, boats, lifebuoys and tracked robots. Its controls include a throttle trigger, grip and switches. CH1 handles rudder, CH2 handles throttle, and CH3–CH5 are programmable. The radio uses 67-channel FHSS frequency hopping. The standard package comprises a transmitter, R6FG receiver, lanyard, manual and packing box, with actual contents dependent on the purchased configuration or shop confirmation. The R6FG incorporates a gyro, supports high-voltage servos and provides up to 400m ground control distance.
Power options comprise six AA batteries, a 2S–4S LiPo or an 18650 lithium battery. The 18650 option requires a JST connector and a battery case measuring 89 × 59 × 25mm (3.5 × 2.32 × 0.98 inches). Integration provisions include an FPV display holder interface and a DSC port configurable for supported simulators or a connected TBS Crossfire unit. The power connection includes reverse-polarity protection. USB connects the transmitter to a computer for upgrading only; the USB port must not be used for charging.
Control functions include memory for up to 30 model parameter sets, ID assignment among up to 10 bound receivers, programmable two-channel mixing and switch-operated dual rates. Cruise control supports crawler throttle adjustment, while the timer provides lap and complete-track results. RSSI and receiver voltage display after binding; model battery voltage requires wiring to the ESC and battery. Battery telemetry supports up to 14S (58.8V) with R8FGH or R16F, or 8S (33.6V) with R7FG or R8FG. R6FG gyro sensitivity is adjustable through STD or CH3.
