Status: online 		steve, if you download the larger image of the 12, it's pretty clear..... the switches have "0", "1", "2", just like the 10X.... apparently, it will have triple rates.

Thanks. I may wait for the 12X.

Status: offline 		I called and backordered a X9303 2.4 system today. At the time I asked if my old 9303 could be sent in and retrofitted with the new 2.4 rf section etc. I was told that the internal parts were all different, all IC stuff, and that the case also would be different. Perhaps the pictures they show on the web site are just touched up photos of the old style transmitters. I cannot imagine the new 2.4 systems having fewer features that the old 9303 and 10X systems that they replace...

The x9303 is probably the 9303 mechanically and cosmetically, with completely new innards. But probably identical software. This is all sounding pretty good to me.

Notice the 9 channel RX antenna.... one is at 90* on the main RX. Interesting. Must have been something learned from the AR 7000... at any rate, $169 street price for the RX, with one remote RX is sounding pretty reasonable, I suppose. Weren't the 9 ch PCM Dual Conversions around that, or more?

Oh - my source also says "late June - mid July" possible for the 9303, but no guarantees.

I wanted the best of the best( my opinion!) for my scale airplane so I went for the JR top of the line....now it may end up in the box with the old Controlaire Mule receiver!!! The Hanriot, now has an AR 7000 rx...tested but not yet flown.....

Question for Horizon engineers. Can a 2.4G TX be linked to a 72mHz radio for buddy-boxing? (2.4G master, 72m slave)

That would be nice.


Ahem.

they replace the hover pitch and hover throttle trim pots (now digital trim to the pitch/throttle curves) which are now Aux 4 and Aux 5, the pots that were Aux 4 and Aux 5 are now chan 11 & 12.

Huh? He was flying a full scale plane with a DX7? Was it a Cessna 172?

Status: offline 		Definetly some good info here! Can't wait for these new systems to come out! When I read about these yesterday morning on a couple of other sites I was instantly revved up and ready to yank all my 72mhz receivers in preparation for 2.4!!!! Glad to see the release info made it over here as well!

well out of the law. I asked them but no answer came. In UK that is higher and in USA could be even higher up to 1500 mW. Still based on
practical experiments and also what is used in life-saving systems, as in millitary, the power in those frequencies is up to 10 Watts, and
boosting it up might cause coverage distruction; that is due to multiple reflections, which cause subsequent field phase modulations in a
random manner. Simply, if you want to see it, then just drop two stones at ones with one hand in calm wather and the pattern of the
surface is going to be quite similar to what I am mentioning. And as you guess it already - in the Air - those NASTY(!) things are
even 3-dimensional and Invisible, that is why more receivers and antenas are better. The biggest problem is that no one of the
current manufacturers adressed (or wanted to address) this classic problem described since couple centuries ago by the early works
of Maxwel, Faraday etc. and instead ot that they tell us how to programm the features and mixers, which is too simple compared to
that nasty radio-wave propagation. Sure there are many success stories in 2.4GHz but we need to know about the artifacts more
anyway. The future is the for sure the Digital Communication approaches 2.4GHz but let see when that technology will get out of
its baby-stage of ANTENA development for RC. Of course some people prefer to be excited than to look into the problems, but
everybody is free to spend his money as he wants, isn't it. If you want to know more about, check so called MIMO-Antenas for the
Mobile Wireless Communications, WLANS and WCDMA phones; there the developments are about maybe 5 years ahead of that
we see at Spektrum, no jokes, this is very serious multi-billon-dollar business indeed.
Cheers,
Nick

Many thanks for your informative post. 2.4 seems like the perfect solution to all our flying needs and wants, convenience, improved performance, telemetry - interesting possibilities with on board sensors.

However, the transmitting power is obviously relevant to us all, regardless of what we fly. It strikes me as a pretty fundamental aspect that could easily get overlooked whilst we're all busy drooling over the the response, resolution, mixing and other high-tech features of this new digital radio gear. If there's one thing I've learnt during my RC experiences - it's never to assume anything.

The typical FM/PCM radio gear has a transmitting power of 500mW. With the new stuff, I don't really like the thought of flying totally ignorant of some of the most basic and crucial information. Looking at Spektrum's site, on the FAQ page, range is conveniently brushed aside - because there are 'too many variables' - yet it would have been very easy to quantify the precise output powe
