Product overview
The RadioLink RC4GS V3 provides five-channel control for surface models, including cars, boats, remotely controlled lifebuoys and tracked robots. Its handheld architecture combines a grip, throttle trigger and switches, with an FPV display holder interface specified as M6 thread (1/4 thread). CH1 handles rudder and CH2 throttle, while CH3 through CH5 are programmable. Any two channels can be mixed, supporting arrangements such as coordinated front and rear steering. Storage for 30 model parameter sets allows the transmitter to retain settings for multiple vehicles.
The listed package combines the transmitter with an R6FG receiver, lanyard, manual and packing box, although contents depend on the purchased configuration. The R6FG integrates a gyro, supports high-voltage servos and has a stated ground control distance of 400 m. Gyro sensitivity is adjustable through STD or CH3, with the VR switch controlling CH3 by default. Telemetry covers RSSI, receiver voltage and model battery voltage; model voltage requires wiring to the ESC and battery. Higher battery telemetry limits depend on receiver selection: 14S (58.8 V) with R8FGH or R16F, and 8S (33.6 V) with R7FG or R8FG.
Power options comprise six AA batteries, a 2S–4S LiPo or an 18650 lithium battery. For the 18650 arrangement, the battery must have a JST connector, and the specified battery-case dimensions are 89 × 59 × 25 mm. Reverse-polarity protection is provided at the JST power connection. The DSC port can serve supported driving simulators or connect TBS Crossfire equipment. Additional functions include crawler cruise control, switch-operated dual rate and a lap timer. Firmware updates use a computer and USB cable; the USB port is exclusively for upgrading and must not be used for charging.
