Futaba R7003SB 3-channel Air Receiver (18-channel S.Bus) FASSTest

The Futaba R7003SB is a sophisticated, full-range FASSTest receiver designed for pilots who need maximum channel flexibility in a lightweight, micro-sized package. While it features only 3 traditional PWM ports for standard servos, its true power lies in its S.Bus/S.Bus2 integration, allowing it to output up to 18 channels (16 proportional + 2 digital) through a single cable. This makes it an ideal choice for flybarless helicopters, multirotors, and complex fixed-wing aircraft equipped with S.Bus systems or power distribution hubs.

Key Features:

• FASSTest 2.4GHz System: Provides a rock-solid, bidirectional communication link with built-in telemetry support for real-time monitoring of your aircraft's vitals.
• 18-Channel S.Bus Capability: Single-cable connection transmits up to 18 channels to S.Bus-compatible servos, gyros, or flight controllers, drastically reducing wiring clutter.
• Dual Antenna Diversity: Features two coaxial antennas to ensure the best possible signal reception regardless of the aircraft's orientation.
• High Voltage (HV) Capable: Operates safely within a 3.5V to 8.4V range, allowing you to power your radio system directly from a 2S LiPo pack without a regulator.
• Integrated Telemetry: Monitors receiver voltage and signal strength (RSSI) by default. It also includes an EXT-VOL port and cable to monitor your main flight battery voltage (up to 70V).
• Flexible Port Programming: Ports 1 and 2 can be reassigned to different channel outputs or S.Bus modes using 11 different programmable configurations.

Integration Tip:

When setting up the R7003SB, remember that Port 2 is multifunctional. Depending on your chosen mode, it can serve as a standard PWM channel, the S.Bus2 telemetry port, or the External Voltage input. If you plan to use telemetry sensors, ensure the receiver is linked in FASSTest 18CH mode; the 12CH high-speed mode disables telemetry to prioritize ultra-low latency.
