Yeah, I know, saw it first a couple of months ago when Robbe was still trying to get it certified. Hope it works better then that other 2,4 ghz system.. uhh spektrum. :)

Can someone make me smart on this. I know if I buy a "normal" radio system here in Germany it will do me no good back in the states. Same goes for my Stateside systems I brought with me. If I get one of the new 2.4 systems will I be legal here and there?

What sort of problems do you see with spektrum?

I have a Spektrum DX6 and also the Pro module for my JR R1 and I dont have a problem with either system. I use the DX6 for boats only and the R1 for my cars and I am building a boat for it now. I like the system I hope Futaba's offering is just as good so that JR will start making even better systems.

Just my $.02

I'm not having any problems since i'm not using it :p
However, i do now some guy's that use it, and are having problems with signal loss and the like...

The first Spektrum systems and modules had a slight lagg that was making high end racers lose races. There were also some problems with signal loss as well. JR solved these issues and the newer radios dont have this problem. The good (fixed) reciever to get is the SR3001 (3 channel) I dont know about the 2 channel one. The DX6 came to the market with the initial release problems fixed so that system will not have the reception and lagg problems. I can vouch for the reception on the DX6 radio I have it installed in my Atlantic Tug and have had it well over 100M away from me with good control (I had to use binoculars just to see the boat).

Yes. 2.4Ghz is a worldwide standard.

[green-boat]

kmot,

You might want to change the thread title to GHZ. If memory serves me right I don't think that there is an R/C band at 2.4 MHZ.

[Kmot]

Woops! :p

[Umi_Ryuzuki]

AAaahh,....

Now will the pots on the Robbe optional twin stick module syncronize with the futaba 2.4ghz system pots?

:)

[Snooptalian]

Looks good, but my DX3 works great so far...Especially as that 3PK spektrum is $600 +...

[Aerominded]

cool!

[ThrustTugKeith]

Now...if they could only make "programming" the radio simple, for old idiots like me!!!!!!


S. :confused:

The reason this is good news, is because as all the various radio manufacturers switch over to 2.4Ghz systems, they will come down in price. Then everyone will be able to reap the benefits of the 2.4 Ghz system and very soon radio frequency conflicts will be a thing of the past.

It should be noted that at the opening of the "Foss Cup" it was announced that there were some 2.4ghz frequency conflicts that occured at a previous run, possibly the Barnaby Regatta.

So 2.4ghz will make conflicts more rare, but not eliminate them,... yet. ;)

Couldn't agree more.Just like mobile phones,plasma and lcd big screen (42 inch)television sets.They start off filthy expensive :eek:
But then they come down to a more affordable price.Did i mention Lipo batteries and brushless motors? ;)

[patmat2350]

Hmmm, Umi... sounds just a little too anecdotal to me. I wonder what evidence they have for a conflict?

I've occaisonally checked in on the Spektrum "actual field results" thread:
http://www.rcgroups.com/forums/showthread.php?t=452817

and not found any reports of conflicts... but it's at 100 pages now, could be something in there! But to my knowledge, the flyboys are tending to let Spektrum users off the hook for radio impound. And if you do insist on impound- how do you decide how to let people run? Either you trust the technology, and let anyone operate at any time... or you don't trust it, and require either only one user at a time, or some kind of cross-check for interference for each additional user coming on line... and how would that work?

I did find something of interest on the above thread- apparently, the DX6 Rx only puts out a 3v-high signal pulse (that's the white wire; still supplies full 5 or 6v to the servo's motor on the red wire)... some servos and ESCs may expect a 5v high pulse, and might not control reliably on the 3v signal. I wonder if that was the issue?

Perhaps KeithS could elaborate, I believe he was the one that made the announcement, and attended the Barnaby run, or was present when where the incident occurred.

I was at Burnaby as well - a fellow boater there had a new radio in the 75 band which when he turned it on cycled and chose a channel - for instance 81. What he neglected to do was to then pull the peg off the frequency board so the other 81 user knew it was in use. When the fellow turned his radio off, second user turned his on, first radio then registered that channel as "in use". It was a lack of being familiar with what he had just purchased, not overlapping channels and nothing to do with the new radios. I think Keith will concur with this explanation.

Maybe the signal strength is why my Proboat ESC did not work right in my boat. I was using a Spektrum AR6000 and the ESC would cut out at times making life miserable. Thankfully I was doing sea trials in a small pool.

What you are describing sounds like a Tracker radio from Aristocraft, not a Spektrum Radio on 2.4 Ghz. With a Spektrum radio the user does not know what channels it is on and selects new channels everytime it is powered up.

Not a Spektrum.

Thanks

True, wasn't the 2.4 style.
