 Hi guys,
im setting up a Bobcat with the Spektrum 18X and a  Spektrum12020 receiver, TM1000
power supply is thru a Powerbox Gemini with 2 x 2300 mA LiFe packs.
ive plugged the TM1000 telemetry module into the data/bind port and batt 1 into batt port and batt2 into the srxl port
Ive selected the Powerbox option on the transmitter telemetry menu , but I get only a single battery voltage readout.
there is a single Rx batt voltage option with alarm options which I can't ddisable how do I get both pack voltages on my Tx ?

you cant.. its nominal bus voltage... you can hook separate volt wire to a separate source like turbine batt.

Dustin has begin to put together a categorical listing of DX18 topics here.. check it out....

I must say, love this radio.

Thanks again for all the help,

i am looking for a new radio, since i will start flying jets soon.
I have an old jr 9303 2.4 and 6-7 RX, but want somthing new.
I really liked the dx 18, since i can use my Rx. with it, but i saw, somewhere, that it may has some range problems and some glitches in the screen.
Do you have any issues with it?
Should i go with it, or maybe get a 12x?
I don't want to start a brad war here, just wanna know what is better for me and for my $$ jets.
Thanks.

Go with the DX-18. I'm not aware of any screen glitches.

The 12x is an excellent transmitter but it is beginning to show its age in terms of features. It doesn't have a lot of the things found on the DX-18 like a memory card, and on-line firmware upgrades to name just a couple.

The DX-18 has the best range of any spread spectrum Tx that I've seen. The crossed antennas on the transmitter really cut down on signal fades. The standard Spektrum/JR DSM2/DSMX transmitters have excellent range due to the signal processing gain from the DSSS processing algorithm, but the DX-18 with the crossed Tx antennas is even better. Many folks with DataLoggers have noted this.

(PS. I'm not affiliated with JR/Horizon/Spektrum in any way and also am not interested in starting a brand war. If you like Futaba stuff, stick with it.)

I don't know much about the new JR XG series. As best I can tell their modulation system (DMSS) is very similar to DSMX but is not compatible with it. If you have a lot of Spektrum receivers, old JR DSM2/DSMX receivers, or Horizon/Parkzone bind and fly models, none of these will be compatible with the new JR XG (DMSS) radios. The only other issue is that JR cannot use separate remote receivers as Spekrum holds the patent on these. That's probably not a big problem. Again, I'm not trying to start an argument here. Futaba seems to work OK without remote receivers, but I'm personally a fan of them, especially in planes with a lot of internal metal, like turbines.

Frankly, I'm at a loss for why JR has abandoned DSMX, at least in the U.S. Because of the huge micro bind and fly Horizon market and the large amount of Spektrum 2.4 GHz equipment already in use (and incompatible with the new JR systems), this is REALLY going to affect their U.S. sales. I'm sure there's a story there between Horizon and JR, but we'll probably never know the details. I could GUESS that on one hand JR was tired of paying Horizon royalties to use DSMX and on the other hand, Horizon was tired of JR's reluctance to meet their requests for new features....

Where does this information come from? A patent? Many systems allow you to link multiple receivers, would this not infringe on Speks "patent"

Status: offline 		Slightly irritating an updated DX18 comes out 3 months after I got this one. Not bothered by the QQ labelling all over it...I can live without that but I read there are improved ergonomics and programming. Sucks if we can't upgrade DX18 to those. e.g. 3 servo per wing matching?

No improved ergonomics on the 18QQ transmitter. Same case and special programming.

Johnny,

What about that special programming, we were all sold on the fact that the DX18 would be software updatable. Even if the software was a small fee I don't think that so many of us would be feeling a little violated right now....

OK. Take your word for it John. I mis-interpreted this then "The Special, limited edition DX18QQ Somenzini radio from Spektrum takes the already acclaimed DX18 platform to new heights, offering R/C pilots the very best in control, ergonomics and features as specified and tuned by Quique himself."

Wouldn't mind one of those "Sol de Mayo Transmitter Case"? Can we get those separatley? The regular Spektrum stand up cases don't accomodate the height of the DX18.

I really hope we can atleast get a version of the software that lets you cycle back to the main setup screen without turning the transmitter off and on. John?

For $34.00 It is an excellent case. The Spektrom decals came with the TX from Horizon.

Are you able to transfer models to the QQ using an SD export/import from my naked 18 or is there an incompatibility associated with software differences on the QQ......hope so as I just completed moving 8 planes from my 12 X.....a bit of a PITA..

TIA.....Tom

I wouldn't want to have a switch combo that could cause me to kill it, other than hitting the power switch.. I use the Back button as a trainer button..

Would you be a little more specific about how you cut down the insert? Maybe even a photo of two TX's in the case? I have the 18 and an 8 I carry to the field for buddy box purposes. It would be nice to carry them in one box.

Thanks
