Product overview
The RadioLink R4F is a four-channel radio receiver for model control, with cars and boats identified as its applications. Its physical configuration combines a 32 × 17 × 11.5 mm receiver body, a weight of 4 g and a 205 mm antenna. These dimensions define both the space needed for the receiver and the antenna length to accommodate during installation. Electrical integration requires a 4.8–10 V DC supply; operating current is 30 mA, and channel resolution is 4096.
The R4F operates in the 2.4 GHz ISM band, spanning 2400–2483.5 MHz, and uses FHSS with a 67-channel pseudorandom hopping sequence to help reduce interference. Transmitter-to-receiver delay is 12 ms, while real-time telemetry provides RSSI and transmitter voltage information. Its 400 m control range carries a specific qualification: maximum range is measured in an unobstructed area free of interference. Transmitter selection must follow the named compatibility list, which includes RC8X, several RC6GS and RC4GS versions, and specified T-series transmitters.
