Key Features
- FASSTest 2.4GHz Bi-Directional Communication System — The receiver communicates two-way with your FASSTest Futaba transmitter in both 18-channel and 12-channel modes, allowing real-time telemetry data to flow from your aircraft back to your transmitter, providing crucial flight information like battery voltage, altitude sensors and system diagnostics that enhance safety and flight awareness.
- S.BUS2 Telemetry Port with Extended Sensor Support — The dedicated S.BUS2 port unlocks an impressive array of Futaba telemetry sensors, enabling you to monitor everything from engine temperature and fuel consumption to altitude, airspeed and GPS data, transforming your transmitter into a comprehensive flight data centre.
- 8-Channel PWM Output with S.BUS/S.BUS2 Port — Eight standard PWM output channels (1-8) allow direct connection of conventional servos and speed controllers, whilst the simultaneous S.BUS and S.BUS2 ports support digital servo integration, giving you complete flexibility in building your custom RC aircraft system.
- 26-Channel S.BUS Capability — Beyond the 8 PWM channels, the receiver supports up to 26 channels via S.BUS protocol, providing exceptional scalability for complex aircraft with numerous control surfaces, flaps, retracts, lighting systems and auxiliary functions.
- Dual RX Link System for Redundancy — For maximum safety in critical applications, you can install two FASSTest receivers in the same aircraft, creating a failsafe backup system that automatically switches to the second receiver if the primary signal is lost—an essential feature for high-value aircraft and professional operations.
- Dual High-Gain Antenna Diversity — The receiver features two high-gain aerials with sophisticated diversity logic that continuously selects the strongest signal path, eliminating dead zones and ensuring rock-solid reception even when flying through challenging terrain or near RF interference sources.
- Extended Voltage Support (3.5–8.4V Operating Range) — With a power requirement of 3.7–7.4V and an operating voltage range extending to 8.4V, plus a dedicated 70V DC extra voltage port for telemetry sensors, the R7308SB accommodates various battery configurations and high-voltage sensor systems without requiring additional power regulators.
- Ultra-Lightweight Construction at 11 Grams — Weighing just 11 grams, this receiver minimises your aircraft's weight budget, allowing for greater payload capacity, improved flight times and enhanced aerobatic performance without sacrificing the advanced features serious pilots demand.
- Compact Form Factor — The 38.8 x 24.9 x 14.3mm dimensions mean the R7308SB fits into confined spaces within fuselages, nacelles and tight installations where larger receivers simply will not fit, giving you maximum design flexibility when building custom RC aircraft.
Technical Performance
The R7308SB represents the convergence of traditional RC receiver design principles with modern digital protocol innovation. Built to exacting Futaba quality standards established since 1962, this receiver combines ceramic-based RF circuitry with advanced signal processing algorithms that deliver predictable, latency-free control response across all eight PWM channels. The FASSTest protocol operates on the crowded 2.4GHz frequency band with frequency-hopping and spread-spectrum techniques that provide genuine interference immunity, a critical requirement for UK RC flying where airspace can be congested with WiFi, Bluetooth and other unlicensed RF sources. The dual high-gain antenna system with antenna diversity switching represents state-of-the-art reception technology; the receiver continuously monitors signal strength from both aerials and instantly switches to whichever antenna path provides superior signal quality, eliminating the momentary dropouts that plagued older single-antenna designs. Power delivery is clean and stable across the 3.7–7.4V nominal operating range, with voltage monitoring circuitry that permits optional telemetry feedback of actual supply voltage to your transmitter display. The S.BUS2 architecture supports simultaneous operation of multiple telemetry sensors through a single serial data line, reducing wiring complexity whilst enabling sophisticated sensor networks with GPS receivers, airspeed sensors, variometers and environmental monitors. The construction quality reflects Futaba's heritage: precision-moulded plastic housing, conformal coating on the PCB for moisture resistance, and ruggedised connectors rated for repeated insertion cycles. Engineering tolerances on frequency accuracy, signal timing and output jitter are held to tolerances far tighter than hobby-grade equivalents, ensuring predictable handling characteristics across different weather conditions and environmental factors.

Frequently Asked Questions
- Is the Futaba R7308SB suitable for beginners to RC aircraft? — Whilst the R7308SB is a highly capable receiver, it is most appropriate for intermediate to advanced RC aircraft pilots who understand telemetry systems, multi-channel control and have experience with FASSTest transmitters. Beginners should start with simpler, single-channel or basic dual-channel receivers before progressing to the complexity of the R7308SB system. However, the receiver's robust build quality and reliable signal reception make it an excellent choice once you have developed foundational RC flying skills.
- What battery voltage does the Futaba R7308SB require? — The receiver requires a power supply between 3.7 and 7.4 volts for normal operation, with an extended voltage range of 3.5–8.4V for brief periods. This means you can power it with either a single 2S LiPo battery (7.4V nominal) or a 3S LiPo battery with a voltage regulator, or traditional NiMH receiver packs. The extra 70V DC port supports separate high-voltage telemetry sensors without affecting receiver power delivery.
- Can I use the R7308SB with non-Futaba transmitters? — No, the R7308SB is specifically designed to work exclusively with FASSTest protocol Futaba transmitters. It is not compatible with other RC manufacturers' radio systems such as Spektrum, FrSky or Futaba systems using older protocols. Ensure your transmitter is confirmed FASSTest compatible before purchasing.
- What are the differences between the R7308SB and other Futaba receivers? — The R7308SB distinguishes itself through simultaneous support for PWM, S.BUS and S.BUS2 protocols, dual high-gain antenna diversity, the Dual RX Link redundancy system for dual-receiver safety, and telemetry capabilities via S.BUS2. Simpler Futaba receivers may offer PWM-only or S.BUS-only options without the advanced telemetry and dual-receiver redundancy features that make the R7308SB preferred for professional and safety-critical applications.
- How many servos and devices can I connect to the R7308SB? — The receiver provides eight direct PWM outputs for conventional servo connection plus S.BUS and S.BUS2 ports that support up to 26 total channels of digital control. This means you can connect eight servos directly to PWM outputs, or utilise digital servos on the S.BUS ports to control additional functions, giving extraordinary flexibility for complex aircraft with flaps, retracts, landing gear, gimbals and auxiliary systems.
- Does the R7308SB support telemetry sensors? — Yes, the dedicated S.BUS2 telemetry port supports an impressive array of Futaba telemetry sensors including voltage monitors, temperature sensors, altitude sensors, airspeed sensors and GPS receivers. All telemetry data flows bi-directionally back to your FASSTest transmitter for real-time display, providing crucial flight information to enhance safety and operational awareness.
- How does the Dual RX Link system work? — The Dual RX Link system allows installation of two R7308SB receivers in the same aircraft, creating failsafe redundancy. If the primary receiver loses signal contact with the transmitter, the system automatically switches control to the second receiver, ensuring your aircraft remains controllable even if one receiver fails or loses signal.
- Is the R7308SB weatherproof for outdoor flying? — Whilst the R7308SB features conformal coating on the PCB for moisture resistance, it is not fully waterproof and should not be submerged or deliberately exposed to heavy rain. However, the rugged construction and moisture-resistant coating make it suitable for typical UK outdoor flying conditions including light rain and high humidity typical of British weather.
