Need help?Do you have a question about the FUTABA R204GF-E and is the answer not in the manual?
The Futaba R204GF-E is a 4-channel receiver designed for use with Futaba S-FHSS or FHSS 2.4GHz system transmitters, specifically for EP (Electric Powered) Car models. It features auto-detection for the S-FHSS/FHSS system and includes a built-in antenna.
The R204GF-E receiver operates on the 2.4GHz band and is designed to establish a secure link with a compatible Futaba transmitter. Each transmitter has a unique ID code, and during the linking process, this ID code is stored in the receiver. Once linked, the receiver will only respond to that specific transmitter, ensuring reliable control. This linking process involves placing the transmitter and receiver close to each other (within 0.5 meters), turning both on, and then pushing and holding the Link switch on the receiver until the LED on the receiver changes to solid green, indicating a successful link.
The receiver supports two operational modes: "Normal mode" and "High Speed mode." In "Normal mode," the receiver is compatible with any type of servos or peripheral equipment, with a frame rate output of 13.6ms. This offers broad compatibility for various setups. The "High Speed mode," on the other hand, is designed for digital servos, including the BLS series, and most brushless ESCs (Electronic Speed Controllers). In this mode, the frame rate output is significantly faster at 6.8ms, providing quicker response times for high-performance applications. It's important to note that some transmitters may not be compatible with the "High Speed mode."
A key feature of the R204GF-E is its auto-detection capability for the S-FHSS/FHSS system. Once the receiver detects either S-FHSS normal mode, S-FHSS high speed mode, or FHSS mode, the detected mode is locked as long as the power is ON. If there is a need to change the operating mode, the receiver's power must be cycled.
The receiver includes a Battery F/S (Fail Safe) function, which is designed to provide a safety measure in case of low battery voltage. The operation channels for the F/S function may differ depending on the transmitter used. When operating with FHSS, the Battery F/S function becomes active only on CH2.
The R204GF-E is specifically designed for EP Car models. Due to its specialized design, its use in other types of models, such as gas-powered models, is not recommended.
When operating in "High Speed mode," it is crucial to use Futaba digital servos, including brushless servos. Analog servos are not compatible with this mode, and their use may lead to servo trouble.
The receiver provides visual feedback through an LED indicator to communicate its status. An "Off" LED signifies no signal reception, while a solid "On" LED indicates that signals are being received. If the LED blinks, it means that signals are being received, but the ID is unmatched, suggesting a potential linking issue or interference. When the Power On/Fail Safe (F/S) function sets, the LED will blink early for the first second.
For optimal performance and safety, it is recommended to place the transmitter and receiver close to each other during the linking procedure. After linking, it is essential to cycle the receiver power and verify that the receiver is indeed under the control of the intended transmitter by checking servo response to throttle input and other controls. This step is critical to prevent accidental linking to another S-FHSS/FHSS system, which could lead to dangerous situations.
While the manual does not explicitly detail maintenance features, it provides important warnings and precautions that contribute to the longevity and safe operation of the device.
