Key Features of the Futaba R404SBS Receiver
The Futaba R404SBS is packed with features that make it a standout option in the market. Here’s a breakdown of its key specifications and capabilities:
1. Futaba T-FHSS SR Protocol
The R404SBS utilizes Futaba’s T-FHSS SR (Super Response) protocol, which ensures ultra-fast response times and stable signal transmission. This makes it one of the fastest receivers available, ideal for competitive racing applications where milliseconds make a difference.
2. 4-Channel Receiver
This receiver supports up to four channels, which is perfect for most RC cars, buggies, and trucks. The extra channels allow for additional controls such as brake bias adjustment, traction control settings, or additional accessories.
3. Full Telemetry Support
The telemetry functionality of the R404SBS provides real-time data on parameters such as:
- Receiver voltage
- Temperature
- RPM
- Throttle position
- External sensors for further customization
This feature is particularly useful for serious racers and professional drivers who need real-time performance data to fine-tune their vehicles.
4. High-Speed Performance
With low latency and a high-speed response, this receiver is optimized for Futaba’s high-end transmitters, such as the 7PXR and 10PX, making it the go-to option for serious racers.
5. Compact and Lightweight Design
The R404SBS is lightweight and compact, ensuring it fits easily within tight RC chassis layouts without adding unnecessary weight.
6. Diversity Antenna for Enhanced Signal Stability
The dual diversity antenna system enhances signal reliability and reduces interference, ensuring a consistent and uninterrupted connection between your transmitter and receiver.
7. Compatible with 2S LiPo Power
Unlike older receivers that require voltage regulators, the R404SBS supports direct 2S LiPo battery power input (3.7V – 7.4V), making it versatile for high-performance applications.
Performance and Testing
To assess the real-world performance of the Futaba R404SBS, we tested it across different RC platforms, including 1/10 scale touring cars, off-road buggies, and high-speed RC drift cars.
1. Speed and Response Time
The SR (Super Response) mode was particularly noticeable in high-speed racing. Compared to other Futaba receivers and competitor brands, the latency was virtually non-existent. The response time felt instantaneous, providing exceptional control over throttle and steering inputs.
2. Signal Reliability and Range
- Indoor Testing: Even in an indoor track environment with metal structures that could cause interference, the signal remained rock solid.
- Outdoor Testing: We pushed the receiver to its limits in an open field, and it maintained a stable connection well beyond the range of practical use.
3. Telemetry Accuracy
Using Futaba’s telemetry system, we monitored the voltage levels, temperature, and RPM in real-time. The data was accurate and updated without noticeable delay, making it a valuable tool for serious tuners and racers.
4. Durability and Build Quality
The R404SBS receiver is encased in a high-quality plastic shell, providing durability against vibrations and minor impacts. We tested it in a dusty off-road track, and the receiver performed flawlessly without any signal dropouts or errors.
