Not to pee on anyone's Cherios, but if you put an offbrand module in a radio and it crashes into a crowd, who would be liable, the flyer, the radio manufacturer, or the module/receiver maker? I have no knowlege of this product but before I would release it for public consumption, I would be darn sure it worked as advertised so I hope they are doing their homework.

Gordie,
Quite simple.....yes
In this society passing the buck would become so fast that you couldn't keep track and in the end they ALL would share responsibility in some way, but the Pilot would be most at fault.

The radio manufactures strictly spell out that you cannot "legally" use any other module on your radio, but the one that the manufacture intended it to be used with.
Those Hitec units that everyone was using on 8U's and 9C's for years come to mind.

I wonder if it will work ok on a 9Z?
The frequency is set in the radio if you have the synth module. I wonder what the radio would make of this box?

I think it is REALLY cool and hope it goes further than Spektrum did.
However I would like to see a "legal" unit come out from Futaba for my radio, just to cover my proverbial buttocks.

GM1,
This is just my guess. I imagine that the module design will have to go through some FCC certification (granted, it's likely a far easier certification than 72Mhz.) Once that's done, the AMA will likely give their blessing.

After that, it would be just like it is right now. However there will be one more party to sue. In this case the module company will be an additional involved party. The courts sort it out from there.

It was only a matter of time before somebody releases it.

Although I never had a problem with my PCM receivers, I would love to get Spektrum just for peace of mind.

Read it closer. It's already got FCC, IC, CE and ETSI approval.

A few things to think about...

The 4096 resolution of this unit will not be realized with any of our current computer radios except the 12Z and 14MZ. Even in PPM mode, the current radios except the 12Z and 14MZ still only put out 1024 steps of resolution. All the math in the radio is geared towards and optimized for 1024.

Since the radio will undoubtedly have to be used in PPM mode, how is one going to get more than 9 channels out of the radio? Even the 12Z and 14MZ only transmit up to 9 channels in PPM mode. Multiplex are the only PPM mode radios I know of that have more than 9 channels.

> I wonder if it will work ok on a 9Z?

> wonder what the radio would make of this box?

I would assume the radio will see it as a fixed frequency module.

Gordie....it is your home owners policy that will be sued first. Then AMA insurance....providing you are on AMA ground flying in AMA air and holding an AMA banner while you fly (or the coverage will not be in effect). Then they can go for the deep pockets.

This liability thing is scary. We have been very lucky about libility to date. I hope I am never the one breaking new ground on a helicopter injury claim.

I love to see the new frequencies come out. Being shot down or turning on on the same frequency is more of a concern right now than the scary new frequency. A lot of guys are running Trexes on this technology and it work well for them. (of course I saw a LOT of Trexes go in at IRCHA...) I'm not ready to load up the Aurora on this receiver, but I am extremely hopeful that they get the buggs worked out on this new technology soon....cause I want one.

To me it seems funny how a lot of the post above are all afraid of this new system i.e "what if it goes out of control and kills some people" kinda stuff. While yes this is a concern if it didn't work correctly chances are it will work and is a hell of a lot more safer then what we have in place now. All you have to do now to have a heli go "out of control and kill everyone in site LOL" is have some idiot turn on his radio. This has happened to me and the heli was a total loss. I for one embrace this new technology because it will eventually be the way of the future. I've been waiting for this to come for some time now. To me people seem to have a sky is falling approach to this hobby. A lot of the folks that I've interacted with are so afraid of what might happen if this goes wrong..or maybe that may happen. Im not referencing any particular post just my observation in general. I think this system is going to be as good if not better then the systems that controlled the rc cars. At least when I was racing cars if someone turned on to your channel you would loose the race or crash the car until the spectrum came along. The heli or plane is not as crash resistant as cars are, so in that respect it will be even more valuable. Plus the telemetry features of these systems are awesome. Being able to receive live data is a great feature and has many uses. I hope they get this system in our hands soon as I will be first to have it no doubt.

I'll try one with my 12mz. Why not???

Now, the REAL question.....which is available FIRST??

BTW, I agree with John, the 9Z would see it as a fixed module.

With the exception of the 3rd party module this isn't any different than anything we have today. We have 3rd party RXs (FMA, Berg, Hitec, etc.) Oh, you forgot about that third party battery manufacturer being liable as well....

I'm using a spektrumized 6102 and can only see good coming from a shift away from 72mhz to 2.4 ghz. I haven't had a glitch on any heli/plane i've flown in nearly a year.

And about the liability issue...I'm much more likely to get into a lawsuit issue driving my car than flying my heli...of course, i'd also advise you to stay off the roads when you see me coming...

Do you use the radio in PPM mode or PCM mode? I would imagine that you need to switch to PPM mode... and then your ability to set a failsafe from within the radio goes away.
This does away with PPM completely, the mode of transmission is completely different than what you are used to with either PPM or PCM coding. And, you can't use your old PCM or FM receiver, you need to use THEIR receiver. And if you read the specs, the new system has the fail safe feature.

I'll guess that you set your TX for PCM mode, then let the new TX RF module handle the actual data transmission.

Dave,
They are referring to what mode you put the radio in. You put the radio in PPM mode and then the plug-in module measures the pulse widths and encodes and transmits the data.

This is the same way the DX6 works. The tx front end is simply sending the Spektrum RF board a PPM stream just like would be transmitted to a PPM receiver.

> I'll guess that you set your TX for PCM mode

There would be no point to doing that. Then the module would have to decode the PCM stream, re-encode and transmit it. It is much simpler to deal with the PPM stream which exactly the same for every brand and model of transmitter (except for the "shift", electrical interface, frame rate, and number of channels; but that is quite easy to deal with).

Absolutely, 100% incorrect.

The AMA liability insurance DOES NOT REQUIRE YOU TO FLY AT ANY SPECIFIC SITE, PLACE, or TIME. The insurance coveragd is NOT SITE SPECIFIC. The only thing that matters about where or how you fly to be covered by the AMA liability insurance, is that you fly in accordance with the current AMA safety code. Period.

The AMA liability insurance IS (and has always been) secondary liability insurance. If you have a personal (or other type) of liability policy that will pay, it will be tapped first. AMA's insurance will kick in if your primary insurer denies coverage (or if you don't HAVE a primary liability policy).

JKos -- I caught that after I hit submit -- and added that last sentence to my post.

It's obvious they use the modulation output from the transmitter's encoder that would normally feed the stock RF module in your transmitter. Putting their RF deck in place of the stock TX module and expecting it to sample, digitize, and encode the PPM stream for transmission in their format kind of makes sense, but it is putting a lot more hardware inside that little RF module than just the 2.4 GHz spread spectrum RF stuff. Since they're advertising a 4096 bit resolution, that pretty much means they're looking at the raw PPM output of the encoder and doing all the digitizing, rather than using the already coded PCM data stream from the transmitter's guts. That also puts the onus on the new RF deck to have some pretty stable power regulation and fairly good A/D conversion stuff in it.

It also would mean that you'd pretty much throw away all that cool signal processing and encoding inside your transmitter that would normally go towards cranking out the PCM data for the stock RF module. So maybe that 12 or 14Mz radio is overkill with this system.
