Product overview
The RadioLink RC4GS V2 is a four-channel surface transmitter for RC cars and boats, including single-engine and twin-engine models. Its controls include a throttle trigger, grip, switches and a VR control for default CH3 adjustment. An FPV display holder mounting aperture is specified as M6 thread (1/4 thread). FHSS transmission uses 67 channels, with ground control distance up to 400 meters and simultaneous channel response within 12ms. Any two channels can be mixed, while onboard memory stores settings for up to 10 models.
The package contains one transmitter, one R6FG receiver, a packing box and a manual. The six-channel R6FG integrates a gyro and supports high-voltage servos. Model battery voltage telemetry up to 8S requires an R7FG or R8F receiver and wiring to the ESC, battery and receiver telemetry port. Transmitter power options are six AA batteries, a 2S-4S LiPo or an 18650 lithium battery. The 18650 option requires a JST connector and fit within the 89*59*25mm battery case. The USB port supports computer-based upgrades only and must not be used for charging.
