In the evolving world of RC transmitters, 4 names stand out: FHSS, S-FHSS, T-FHSS, FASST, and FASSTest. these introduced by Futaba, represent advancements in RC communication protocols. While many enthusiasts believe the divergence between them lies solely in their application – ground versus air – the truth is far more nuanced. This article seeks to shed light on the unique features, benefits, and applications of each, going beyond the commonplace myths.
The Relationship Between Those Four
Futaba introduced two distinct protocols: the economic FHSS and the superior FASST. While both were pioneering in their time, evolution was inevitable. Consequently, the S-FHSS(Second FHSS) emerged, representing the second generation of FHSS. This was followed by T-FHSS(Three FHSS), the third iteration of FHSS, tailoring to an even broader market. Parallelly, FASST too saw its successor in the form of FASSTest, the second-generation FASST protocol, crafted for discerning high-end transmitter enthusiasts.
FHSS, S-FHSS, and FASST have been phased out. As a result, Futaba’s RC transmitters now either use T-FHSS or FASSTest. Many people mistakenly believe the difference between them pertains to ground models versus aerial models, but that’s not the case.
If you are interested in T-FHSS and FASSTest, let’s dive in and compare them together!
Comparison between FASSTest and T-FHSS:
Positioning & Target Market
FASSTest: Aimed at professional and high-end hobbyist markets, this is Futaba’s most sophisticated 2.4 GHz protocol. It is reserved for their top-tier RC transmitters.
T-FHSS: A more budget-friendly alternative, T-FHSS brings many of the advantages of FASSTest but at a more accessible price point.
Channel Modes and Functionality
FASSTest: Offers three unique channel modes: 18CH, 14CH, and 12CH. These modes give flexibility to users, allowing them to select based on the required number of channels and telemetry demands.
T-FHSS: It’s known to leverage frequency-hopping spread spectrum technology, ensuring a steadfast control link and considerable telemetry capabilities.
Telemetry Capabilities
FASSTest: Regardless of the chosen mode, FASSTest supports all available telemetry sensor units. It offers a comprehensive view of various data points, vital for advanced users.
T-FHSS: Provides valuable telemetry feedback, including data on RPM, temperature, power system current, and voltage. While not as extensive as FASSTest, it offers substantial insight for most users.
Technological Foundations
FASSTest: Being an evolved version of FASST, it inherits the latter’s reliability while integrating more advanced features, especially in the realm of telemetry.
T-FHSS: Operating on the frequency-hopping spread spectrum technology, it ensures a reliable connection between the transmitter and receiver, reducing interference-related concerns.
Conclusion: Which is Better?
Choosing between FASSTest and T-FHSS boils down to user requirements and budgetary considerations. While FASSTest offers an unparalleled experience in telemetry and flexibility, T-FHSS provides a commendable performance that fits a more budget-conscious segment without major compromises.
