Frequently Asked Questions
- What is the difference between the 14-channel PWM output and the 26-channel S.Bus output? — The 14-channel PWM output provides traditional servo control with one dedicated three-wire connection per servo, allowing direct control of conventional servo motors. The 26-channel S.Bus/S.Bus2 output uses a single-wire digital protocol for compatible devices such as programmable servos, gyros, and telemetry sensors. You can use PWM channels for basic servo control and S.Bus channels for advanced digital devices simultaneously, giving you flexibility to build systems of any complexity.
- Is the Futaba R7314SB suitable for beginner pilots? — Whilst the R7314SB is capable of supporting extremely complex aircraft configurations, it works equally well in simpler setups. If you're starting with a basic trainer aircraft using just four or five servos, this receiver will serve you perfectly and provides room to grow into more sophisticated aircraft as your skills and interests develop. The telemetry features and advanced capabilities are optional—you can use it as simply or as complexly as your aircraft demands.
- What battery voltage does this receiver need? — The R7314SB accepts input voltages from 3.5 to 8.4 volts, meaning it works with single-cell LiPo batteries (nominally 3.7V), traditional receiver packs, and 2S LiPo configurations (nominally 7.4V). Most modern RC aircraft use a dedicated receiver battery to ensure consistent power supply independent of main flight battery voltage fluctuations, and this receiver accommodates virtually any standard receiver battery choice.
- How many servos can I connect to this receiver? — The R7314SB provides 14 independent PWM channels, each capable of controlling one standard servo motor, allowing direct connection of up to 14 conventional servos. Additionally, the S.Bus/S.Bus2 output supports up to 26 channels of digital devices. Many aircraft use a combination—perhaps 8-10 standard servos on PWM channels plus 2-3 programmable servos or gyros on S.Bus channels.
- Do the aerials need to be positioned in any particular way? — The dual high-gain aerials use antenna diversity technology that automatically selects the strongest signal, so you have flexibility in positioning. However, for optimal reception across all flight attitudes, positioning one aerial vertically and one horizontally (or at angles) within your aircraft fuselage generally provides the best coverage. The included aerials are flexible enough to bend without damage, allowing creative installation in confined spaces.
- Is this receiver waterproof? — Whilst the R7314SB is not specifically rated as waterproof, it incorporates robust construction suitable for typical RC aircraft flying. If you plan to operate in wet conditions, covering the receiver with appropriate protective shrink-wrap or encapsulation is recommended to protect against moisture ingress.
- What makes FASSTest technology important for RC pilots? — FASSTest (Frequency Agile Spread Spectrum Technology) is Futaba's proprietary system that provides exceptionally fast response times—essential for precise control during aerobatic manoeuvres—whilst using frequency-hopping techniques that resist interference from other radio systems. At busy UK flying sites with numerous transmitters operating simultaneously, FASSTest's intelligent frequency management ensures your aircraft maintains reliable connection even in congested RF environments.
- Can I use this receiver with older Futaba transmitters? — The R7314SB uses FASSTest protocol and is compatible with FASSTest-equipped Futaba transmitters. If you own an older Futaba transmitter using PCM or other legacy protocols, you would need to upgrade your transmitter to use this receiver. Check your transmitter's manual or contact a Futaba dealer to confirm protocol compatibility before purchasing.
