DX7 compatibility

[teeson]

so im very new to this hobby and what seems to be the Tx on the golden plate is the spectrum DX7. i want to know a lot about it, 2.4 ghz is way more powerful than anything else right? does this thing blow away the competition? is it compatible with anything other than the spectrum receiver? does it use crystals? all the info i can get that makes sense to me :) would be very appreciated. thanx

Please don't take this the wrong way... I'm NOT trying to be rude at all. It's just that there's alot of info about the Spektrum line. We could sit here typing all night answering your questions, or you can go to this web site and read up on it.... This will answer most of your questions, and more..

No it does not use crystals. It is only compatible with DSM2 technology. And 2.4Ghz is becoming the way of the future. All of the major brands are moving in this direction.

More powerful - I doubt it is more than equal to a 'regular' Tx in range.

Blowing away the competition - it does as long as the competition isn't on a dedicated 2.4 GHz like the DX-7 is (like the average pilot will feel the difference with a module anyways).

Receivers - only spectrum Rx can be used with a spectrum Tx/module.

well no offense taken, i did figure there was a lot to learn, but i was hoping somebody would give me a website, so thanx a lot. thanx for all the info however much that may be.

There is 3 players in the 2.4ghz arena.

Spectrum/JR (same thing really) with the Spectrum brand radios DX6, DX6i and DX7 and now the JR x9303

There is Futaba which calls thier system FAAST they implement the band a little differently but its a similar pricipal.

Then Extreme Engineering and their XTremelink modules that are compatable with many module based transmitters from JR and Futaba and use proprietary recievers.

a) The DX7 is also compatible with the Pektrum DSM receveivers, but basicaly each brand is compatible with only other receivers from the same brand.

b) The JR 12X is announced. :)

As for powerful, they all have the same power output (FCC regulated). Power as in programming, the DX6 is least, DX7 next, X9303 next, and the 12X at the top.

I'm not 100% sure about the compatibility issue. It is true that the DX7 will only work with DSM technology, but not necessarily just Spektrum receivers. I linked mine to my Blade CX 4-in1 receiver and it worked fine (maybe somebody knows who manufactures their new 4in1). I also have a buddy with a Futaba 2.4 Ghz system using a Spektrum rcvr on his R/C boat. It works fine. Give it more time and more and more of the manufacturers are going to build products to use that match competitors products. It's all about the money in the end.

One thing I have noticed about the range is that my flying wing responds much better at spec altitude with my DX7 than it ever did at that height with my 72Mhz system. Not that I can see that well in the first place.:(

[Pinecone]

DX7 works with DSM and DSM2 (all Spektrum and JR 2.4 Rxes). Eflite CX2 and Blade 400 use Spektrum based Rxes (and Txes). CX, CP, CPPro, and CP+ are 72 Mhz.

Your friend must be using a Spektrum module in his Futaba radio, as the FASST system and DSM are NOT compatible. They use totally different versions of spread spectrum.

There is word of a Corona 2.4 Rx that is Spektrum compatible. So aftermarket Rxes may come true. And since Spektrum was first and the most systems, it is likely that they will be the first one with aftermarket Rxes. Which will make it that much harder for the other versions to compete.

Pinecone, whatever he's using, I kind of want my receiver back before he sinks that in the lake, too, like he did with his last one!

Correct on the CX2 thing (I said CX earlier). I don't have an E-Flite heli, though. I use that 4in1 rcvr in a Lama V4 I have. Paired with the DX7, that little bird flies 100% better. I was just never sure who manufactured it for E-Flite.

Where did you get just the blade cx2 4 in 1 RX? I want one for my micro viper 3d...

fogger, I bought a CX2 and trashed it all except for the 4-in-1 unit...

j/k - I actually bought it from RC Superstore. Cost something like $59.99. If that wasn't going to work, I was going to try the 3-in-1 with a Spektrum 6100 or 6300 rcvr. It works pretty good, thankfully.

Any idea if it can be configured to control a seperate tail motor type CCPM heli?

Ah, good point. You'll need the 2.4Ghz 4-in-1 for the Blade CP instead of the CX2. I'm pretty sure they're the same price, same source.

[Pinecone]

Or get a 3 in 1 for a Blade CP Pro and use a separate Rx.

I converted my Blade CP to JR using a CP Pro 3 in 1 and a Light Flight RC/Corona Rx.

Now converted to Spektrum using an AR6100.
