Actually they added 12 channel PPM support with the latest software upgrade. Now, have anyone heard of a 12 channel PPM receiver???

Hmmm - the plot thickens!

Again, if using PPM, I will get a Spectrum module just in spite!

I want one

Tor,

I'm not the full bullet on all the features with the new system but I have some idea of whats in it.

The 14MZ and 12Z modules apparently will use the native Futaba pin out so your going to have 2048 resolution on either PPM or PCM. I dont see what all the fuss is really about as both a extremely fine resolution. Correct me if I'm wrong here but the 2048 and 1024 refers to the maximum steps recognised within the radio of each of the gimbals. The modules in the 12 and 14 are currently able to use that and transmit it. Thats why if you cut back your ATV your really killing your resolution. That has nothing to do with whats being transmitted, it just means you have narrowed the amount of steps you can send to the servo. In short a measure of how fine your contol can be.

Funny thing is most of todays top servos are only good for 900 or so steps. Work that one out.

Now latency is an altogether other story. Thats the time it takes for the signal to be recognised, digitized and transmitted. PPM is raw and fast. PCM is packets, coded, shaken and rattled and transmitted. If the numbers dont match you get a lock out or fail safe.

The G3 Futaba system got PCM to outstanding transmission times. Twice as fast as the conventional PPM in fact.

So the 2.4 system should have reduced latency, faster data processing (2048). I dont see how the other guys system can be better or worse in any way what so ever, plus it will only be an 8 channel system and not 14. If I was that pedantic about it I would buy a 7 channel and save some funds.

Guys we will try to get a Futaba rep in here to help answer your questions in much better detail but please remember these guys are home tonight, its Easter Friday here tomorrow so thats a holiday and likely a black hole for information as well.

If however we locate a guru lets give him a chance to come in and answer your concerns accordingly.

Kiwi, I fully agree that resolution is a non issue.

But as you said the latency of G3 is less than PPM and outstanding in that way. No way I am going to get a module that uses PPM for internal communication between the module and the transmitter.

If this is the case, I think Futaba took the easy road and screwed the 12/14 users in the process.

Edit:
But peace out! Let's hear it from the source before jumping to conclusions....

I Have my 12z in for service. I want to be upgraded

How did they screw the 12/14 users. It's already been stated that all 14 channels will be in use.

If PPM is faster anyway then PCM, and with 2.4ghz you don't have the concern of getting shot down, then where is the problem?

FUTABA

Looks like they caught up on the ball!!! My 12 is gonna see either a upgrade or a module BABY

All the more reasons to fly futaba!!!!

Spektrum aint got nothing on us baby!!!!!!!

Alright guys, Max has already asked that we don't drag this thread down by attacking ANY manufacturers, so please let's keep it friendly.

Tor,

I think we are flogging a dead horse here. The modules for the 12 and 14 are 2.4 Ghz and 2048.

Wheres the easy road and how does that screw the 14 and 12 owners out here.

Guys you dont need to send your radio in for any modifications. These modules are plug and play.

I suppose there might be a software upgrade to tell the radio your on 2.4 but I dont know that for sure.

And of course you will still have your 72Mhz modules and rx's for those other planes in the hanger.

Its a win win situation. I dont see anyway anyones getting screwed here, quite the opposite in fact.

Awefully strong language on something you have no personal knowledge of!
It was stated by Frank Noll Jr who would have personal knowledge

"When using the 12Z & 14MZ modules the processing speed will be
equal to the current systems. You can figure everything that the 12
& 14 does now, will continue with the 2.4 FASST modules."

Futaba has more than done right by the consumer by not just launching a new 12FG 2.4, but also supporting past customers with an easy upgrade for their present equipment. As my Dad would say, "I think you need to cool your jets".

Ok Ok if you must.

[JeeUm]

I must

[torkboy]

Fine with me

The problem is PPM is not faster than PCM-G3 (who cares about 14 channels, I don't atleast - I got the 14MZ for the speed). Your premise is wrong, since you are comparing with PCM1024. Hence, if the 2.4Ghz modules are using PPM for internal communications it will be slower than 72Mhz (or in my case, Europe, 35Mhz) PCM-G3.

I don't want to jump to conclusions, as I edited and wrote in my previous post. Let's see what Futaba says.

[Tram]

Would it be possible to have an old FM module out of say a 9CAP and revert the 12 back to FM when not flying with a 2.4 RX?
