It should work with any aircraft JR system that uses a module.

OK now that someone else has gone there well lets just say thats not a in my pocket

Sorry, missed this earlier.. The SPM940 Flight Logger.

Hi from the UK guys,

Any idea as to when you'll be shipping units to your agents in the UK. This is just what I need for my 9x.

Do I spy a Volz servo in the picture?? If so, here's a hint, if you ever get to meet Michael Volz, DO NOT, I repeat, DO NOT, try to out drink him. Sure, he's a little fellow, but don't let that fool you. It's a TRAP!!!!

Ok, so here is a question I have not seen answered. At events like the Joe Nall, Giant Scale racing, ect there is a requirement that when you shut your transmitter off that your engine goes down to an idle or at least pull the throttle back. If the Spectrum system does a "smart hold" where the throttle stays at its last command will this method of shutting down the transmitters at places like the Nall stop? I personally don't like having my throttle being shut down in a signal interruption. I would much rather it stay at the last throttle setting but everyone has their own opinions. But I don't want to see any type of exception made just for one radio. Its a all do it or no one does it type of thing for me.

That's what I've been asking.........it has not been answered......

Since your in PPM mode.......do we lose Failsafe or does the new module/rx combo have its own failsafe like Garret suggested

[crhammond]

Garrett - I'm sure someone else will post - but the way it works is the throttle goes to where you programmed it to go when you bound the radio. Normally that would be idle. If you have an ignition cutoff you could also program that in the off position (for example...) However - the system relies on the user having bound the radio once they get the radio setup completed so that the throttle travels to the right place. Then again - PCM failsafe and IDP also rely on the user programming it correctly so I guess this is nothing new.

I'm really impressed with the way you are answering all our questions in a really clear and concise way Danny - awesome job!

I really like my DX-7 but I'm yearning for easier programming and more features. Now that we have modules (and we know the performance is better than PCM - i.e. better than what we had pre-DX-7 - but not quite as a good as DX-7) it's kinda hard to hold off getting a 14mz with a module... kinda the "best of all worlds" right now. And it would work with the AR7000's and 6100's I have too.

It sure would be nice to know if the next DX-x is going to be a high-end compete for the 10x 12/14mz radios or something in between. Can we get a hint as to just if it's going to be high-end vs mid end (i.e. no feature list - just a general statement)?

Since 2.4 has so much bandwidth and is bi-directional it's likely just a matter of time until we see radios with built in telemetry for airspeed, rpm's, altitude etc. Very cool times

[crhammond]

It has failsafe. I works almost identical to Multiplex IDP Rx's (which are PPM with failsafe.)

When you bind the Rx to the Tx where the trottle stick is is where the failsafe position is. I think a few posts back Danny explained the two different methods available on the AR9000. The main difference between this system and PCM failsafe is that you set it via a binding procedure rather than on the radio software.

[sweetpea]

Does that include all other stick positions or just throttle?

I fly with last known position and throttle idle. It doesn't appear that it can do that......only all sticks nuetral or where I place them in binding. Not favorable IMHO.

Maybe this will help. Danny Snyder at Horizon wrote it:

I'm not sure if I'll get all the questions here, so if I miss one ask again if you would.

First, in regards to fail safe. You must set the TX in PPM mode, so fail safe in the TX will not be available, however Spektrum receivers store the fail safe positions during binding. So they have fail safe, but it works differently than your current system. For the AR7000 Receiver (and most other Spektrum receivers) (which is what comes with the DX7) it is set so that the throttle channel fail safe position is stored during the binding process and all other channels are set to hold last position in the event of signal loss. This we call Smart Safe.

The new AR9000 Receiver has 2 modes available. It has the Smart Safe as one option, which to set this you bind the Receiver normally (leaving the bind plug in the Receiver until it completes the binding process). It also has a 'conventional' mode where all channels will be set to fail safe and the positions are stored during binding. To get into this mode, after you power up the Receiver with the bind plug installed, the light begins to flash. Before you turn on the Tx in bind mode, you remove the bind plug from the Receiver and then power up the Tx in bind mode. In both cases you will need to hold the channels in the fail safe positions desired through the whole binding procedure. In Smart Safe mode, only the throttle channel will be set to fail safe, in conventional mode all channels will be set to fail safe. And that applies only to the AR9000 receiver.

The module systems are DSM2 technology, they are not compatible with DSM1 receivers, so the AR6000/BR6000 for the DX6 will not work with the module systems.

The module systems do not have the model match function, that is a function in the programming of the DX7 TX and is not possible with the module systems, since the TX's do not have this function.

In regards to the Futaba being 8 channel, that is correct. Futaba systems only output 8 PPM channels, and with the Spektrum system you must set the TX to PPM. Therefore only 8 channels are available at this time.

In regards to speed, the Spektrum modules speed is the same or faster than existing PCM systems, but it is slower than Spektrum systems built from the ground up such as the DX7 and any future systems that may be developed.

I hope that answers most of the questions.

SCHWING!

One note/question.

With the 40 number being the maximum safe limit it sounds like radio impound at large events will still be a requirement to prevent the scenario where many people are flying or getting in the que and too many others are "just fiddling and tweaking" planes in the pits type of thing. So the habit of radio "control" should not be flushed too quickly.

Would the above be an accurate and safe statement?

Thank you for all the information so far.

Max, dude, you should be a proud puppy. This site has done nothing but get better since I have been a member.

Danny answer that on page 8... you can do it either way:
