The Futaba 2.4GHz Story

2.4GHz FASST logo

In our decades-long history, Futaba has brought many "firsts" to radio-control: Pulse-Code Modulation (PCM)…1024 and 2048 resolution…systems with 9 and 14 channels…transmitters with ultra-reliable dual internal processors. Now Futaba is the first of the traditional radio manufacturers to bring the advantages of 2.4GHz spread spectrum technology to modelers – and the first to introduce that technology in a full-range aircraft system. For getting the full benefits of 2.4GHz technology, you'll find that Futaba's experience makes all the difference. Ask competitors such as driver Taylor James, who has already racked up multiple wins with Futaba's 3PK 2.4GHz! Or award winning pilot Jason Shulman, who says "the fast response and glitch-free performance is unbelievable!"
Futaba takes great pride in making sure that every new product performs flawlessly before it's offered to our customers. Others hesitate to invest so much effort in testing. Some may even consider their "first run" products a step in the process of working out bugs, using feedback from the earliest buyers. Futaba is different. When you choose a Futaba 2.4GHz FASST radio system or module/receiver set, you've selected a fully tested, well-engineered, totally reliable product – one that's absolutely ready to give demanding R/C hobbyists the performance they expect. Our hands-on experience with 2.4GHz technology stretches back 15 years, long before anyone considered its value in hobby applications. That's when engineers in Futaba's industrial R/C division – designers of radio-control tools for construction, civil engineering, and similar uses – began employing and perfecting their own 2.4GHz equipment. Those same engineers were brought in to share their knowledge as soon as we were comfortable that 2.4GHz technology had perfected for the unique demands of R/C hobby applications. No other radio manufacturer had such an instant supply of expertise.
spacer The advantages of Futaba 2.4 GHz FASST systems:
Channel Shifting
Other 2.4GHz systems hold firm to one or two frequencies, increasing the potential for interference. The frequency of Futaba 2.4GHz FASST shifts hundreds of times per second, so there are no signal conflicts or interruptions – and no need for a frequency pin!

Patent # 6,141,392

2.4GHz FASST scans incoming data and applies sophisticated error correction techniques – resulting in a system that gives you a solid, impenetrable connection with your model.

Dual Antenna Diversity
Futaba 2.4GHz FASST systems seamlessly select the best reception between two receiver antennas, so there's no loss of signal.

R603FF, R616FFM, and R6004FF receivers do not offer Dual Antenna Diversity.

Easy Link
Futaba 2.4GHz FASST system transmitters leave the factory with a unique and permanent ID code. Once linked to the receiver, the code ensures that the receiver will recognize and respond ONLY to that transmitter. The linking process is simple...just push a button on the receiver.

Custom-Developed IC Chips

IC ChipFutaba uses custom IC chips that have been designed specifically for radio-control – ensuring quality, reliability, and safety. This is why Futaba FASST systems are faster and more reliable than the competition.

Compact, "All-in-One" Receivers

R617FS 7-Channel ReceiverFutaba's small, powerful 2.4GHz FASST R617FS receiver for flight systems can control giant-scale models as easily as park flyers and weighs a scant 6.37 grams without case. Full-range systems from other manufacturers include a bigger, two-piece receiver, and you must purchase a smaller park flyer receiver separately.

Over 2x Less Minimum Latency

Real-Time ResponseLatency is the elapsed time between your movement of the transmitter controls and servo response. In Futaba 2.4GHz FASST systems, that response can happen over twice as fast – so you feel less like you're "out in front" leading your model, and more like you're inside driving or flying it.

100x Faster Antenna Switching

If the receiver notices a problem with the data coming into one antenna, it rapidly switches to the other, looking for the sharpest signal.

Stronger, More Robust Link

Futaba doesn't need redundant receivers. Instead, we use a combination of Channel Shifting and Dual Antenna Diversity (DAD) to provide a robust, highly dependable link between transmitter and receiver.

Hassle-Free Fail Safe

Futaba 2.4GHz's Fail Safe is programmed right through the transmitter just like PCM1024, PCM-G3, just like on conventional systems. The competitor's radios require a complicated six-step process to set up their Fail Safe, along with a separate binding plug that can easily be misplaced.

TM7 and TM8 adopt other programming step.
