I'll probably get the 9-ch JR 2.4ghz radio when available....but the 12-ch would be ncie too.

I think Spektrum will continue to service the lower end market, 7 channels and less, while JR will concentrate on the high end using the Spektrum technology.

I think that guessing this stuff is useless. Everyone was convinced the 9 channel would be a Spektrum DX9 and look what came out...JR 9303 with Spektrum guts. Even people supposedly in the "know" either don't know or won't tell. Fact is, stuff will be changing rapidly for the next few years so be prepared for something later and greater when you do plop down your cash. Hopefully at least the receivers will be backwards compatible like they are now with Spektrum/JR.

Anybody know anything about EPS (Extreme Power Systems) Tx modules and Rx's for our JR, Futaba and Airtronix radios? Rumor at the field is that we can convert all of our radios for "not too much money".

Well, I can see the resale value of my 14mz starting to nose dive. I wonder if I can write that off on the 07 tax year

If the 12 ch will do both planes and helis I will go back to JR. The only reason I ever went back to futaba was that the 10x would only do one or the other.

Thumbs up though.

I know for a fact that Hitec is going to jump in.

They better do it quick. Of course, they still don't have anything more than a 7 channel radio on 72mHz.

Don't get me wrong, I have two Hitec 7 channel radios, work great, and I love their digital servos...but they have been way behind in the transmitter game for a while.

Now that they own Multiplex, maybe they will adapt one their high channel systems for 2.4. There are couple of guys flying the Royal Evo systems at one of my clubs, and they have great features, but I don't know that I will hold off buying the JR system on the hopes of a potential announcement someday down the road.

This discussion seems to have gone more emotional than technical and thus I would like
to ask a

NEW (to me at least) TECHNICAL-RC-QUESTION here:
------------------------------------------------------------------
- WHAT are the POSSIBILITIES for VIDEO-LINK to ground, if any, from those Spread Spectrum or whatever
GHz- range Systems ? I guess many more than me are having strong interest on that and having such
Spread spectrum System without the Video Link sounds like using an engine on 10% of the power
available, meaning, the PRICES will jump even UP when that is made available, while the system
capabilites (technically) should allow that even by now maybe ?!

Or maybe we have just a Cat-and-Mouse Game in progress, i.e. coordinated Manufacturers/Sales
vs. Customers Game ...

Well, that is natural and that is why I do not jump to put cash yet, the development is still in its
initial stage and in year or couple months most likely we will have big "news", i.e. all this "new"
and "amazing" technology is based on the at least 15 years enourmous development in the Digital
Communications by companies like Nokia, Motorola, Samsung, Ericsson, ... and not much by Futaba
and Spektrum and JR, they are just nobody(!!!) there to make any difference in that multi-billion
dollars developments, although for sure at Futaba and JR they know how to make classic and very
old fassion superhetterodine RC Analog Radios with computer controllers on top of them.

As many know in classic hybrid technology (1990-1992) Phones price was reasonable at Thousand
of Dollars, while now many of them are arround 100 USD due to Monolithic Integrated circuits,
i.e. RC is heading toward Radio-Systems where the prices of many new "toys" are for sure might
drop in ratio 10:1 just in few months/years. Reasonable price for Module of GHz should be in the
range of less than 30 USD, if Sales guys would like to disclose the real prices, which they of course
will newer do. Just to remind, an Integrated circuits chip-set for ISM band (in 2.4 GHz range) cost
about 5-10 USD and has been mounted in many other applications extensively whole the time,
for example in Automotive in very harsh conditions inside of the tyres to measure and transmit
in real time the type pressure. (you can trust quite well that; I am about 15 years in the business
of making those circuits).

I.e. paying n x 100 USD for such upgrade module for RC is just letting the other guys make very
easy money.

Back to the Main Two sub-questions:
-------------------------------------------
A) In more Comercial details the Question would be: - Anybody have seen such video link being
offered by Spread Spectrum 2.4GHz RC systems, if yes, please place the WWW-page or file.

B) Technical Details Needed: Data-Band Used currently, Camera-Types Supported, and as well Power
Consumption and Max-RF-Power of the Transmitter etc more specific than "great feelings about it"
from sales & marketing persons.

Shortly, it is probably very nice to watch where you are flying in Real-time trough the cockpit of your RC,
within the same(!) system you use for control, and What are you ready to pay for it, although the additonal
real cost of it is below 100 USD, and when this will become a "standard" built-in function in RC-systems ??

Thanks in Advance,
Nick

Has anyone mentioned Futaba announcing their own 12 channel 2.4 GHz system. It's called the 12 FG based on the 12Z.

http://2.4gigahertz.com/radios/futk9275.html

Nikolay,

In a few years, we will be controlling our models with satellite systems such as the UAVs.

If anyone is interested, my friend has already crashed a 50cc Aeroworks Extra 260 due to lock-out on his Spektrum DX7, so I guess that the system is not indeed "glitch free operation"! Beware!

I never like to be the first one to get brand new technology because usually there are some
bugs that need to be worked out. Think I'll wait till the dust settles a little more.

Appologies for it sounding so insulting, I should have wrote entry level. I have flowna number of years and most of my planes now have digital servos and it is recommended that y-leads aren't used, with two elevator and two aileron servos and a set of retracts there just isn't enough channels on a 7 channel set (Always running the battery of its own connector) Also, I don't doubt the technology, in fact I am there as soon as I can get my hands on a set that will do the job, just jealous that anyone who can fly with fewer channels has already been catered for.........Maybe you guys can all be my guinea pigs and work out those pitfalls for us

So far we have seen some great beginners pieces of kit in the 6 and 7 channel Spektrum stuff .

Nick
beginners kit? surely you jest
the most expensive radio on the market can be shot down by a kid with a 100 dollar beginner radio
you call that an advanced system?
honestly- I wouldn't trade my DX7 straight across for one of those .

Me again

Just want to say here that I have flown with a bunchof old timers for a long while and they have all been consistently SHOT down over the years, ther was that time one of them came in from way out of the field and slowed his plane to a walking pace and then bang, shot down, and dang if it didn't look just like a tip stall. Another time one was performing an inverted pass over the field and there was that interference again, this time it put full up elevator in his plane and through into the deck.
The point is for some reason people have always used the glitch / intereferance ( I know it does exist and people have suffered from it) when in reality they could be a bit more honest about what really happened. I have always liked to own up when my fingers chose to do the opposite of my brain and have maybe been lucki with only being shot down by my own interferance. Until they start to sell meters to monitor the frequency then no one is going to be able to ever say they have really been shot down. Cannot wait for the guys up my field to get.....maybe some new excuses coming soon

OK all you conspiracy theorists - I've just noticed on the Horizon site that all Futaba Spektrum modules are now not available until "Late June", bu the JR with 9ch is "late April".

That's one way of getting Futaba users to think about jumping ship a bit earlier don't you think!?

Well, it is nice to dream about UAV control over satelite but how do you pevent the bad guys using that
is problem beyond our abilities to resolve. In fact a simple reason is that I am afraid I do not want to
do 3D aerobatics and watch only trought the cockpit - I will get dissy and crash the plane, i.e. lets
keep for the time being the plane in the visual range and look time-to-time outside of the cockpit i.e.
from the ground - the aerobatics is more beatiful. In fact there are several UAV meetings
every year with lot of people on them and the major topic is Aviation Safety in any(!!!)
sense and direction. I believe you support that view for sure.

The differences in all those three (Spektrum, Futaba and Graupner) all are about the Transmitter and
modules for it. But what is not well explained yet is why one needs so many receivers in the Airplane,
and there goes my curriousity; I am not worried about the computer-related functions, they are
always great with Futaba and JR, but the Radio-Waves-Propagation at those frequencies is a well
known problem. How it is solved here and is it solved well enough if(?) Spectrum and Futaba are telling
that if we buy and place more Receivers in the Airplane then the system works better ?!?!? So
how many receivers I should have there 2, 4 or ...??? They are pretty light but still isn't this
kind of disturbing request, i.e. should I cover the whole Aiplane with Receivers ? - Anybody,
who knows and mostly has got EXPERIENCE with the system, please tell the story.

You make a good point but do some reading on the technology. I don't want to jump into something new that has bugs either but the Spektrum full range (2 receivers) system has been in use for quite while and results have been great. It has been flown in giant scale gas, helis, jets, electric jets. I never want to be the first to try something new but I also don't want to be the last.

There was quite a good and brief explanation in a local publication originally ex the AMA newsletter I think. The need for two (or more??) Rx's is to avoid teh signal being blocked by items in thw aircraft like engines, ignitions etc, due to the extremely directional nature of the higher frequency transmission. I'll dig it out and read it again...
