Hope every one had a good christmas!!!


Can anyone please tell me whether the MX22 radio has 10 proportional channels (travel adjust on all channels) and the ability to mix any of the 10 channels to any other. I'm thinking of changing my tranny cos my 9 zap just doesn't seem to have enough channels for my new Balsa Bandit, I just can't get the set up the way I want!!

Thanks in advance

Nick

yes it does, its a brilliant radio, much underestimated!

All as Mick said!
The only down side to the MX-22 is if you use a trainer system for buddy box. The MX-22 does not have this as a standard feature.
As with many of Graupner's radios its a plug in module, which uses fibre optics for the lead, so it is not directly compatable with std JR radio-you need a special RF module to go in a JR tx.
Other than that it has more features than a 10x, plus 30 model memories.
There will be plenty at CJ tomorrow.

Dave, Have you heard anything about possible Spread Spectrum technology for the MX-22? Thanks, Billy

I'm sure that the plug in RF module option will become available for all JR type Tx's
I don't know of timings-more info will be available early Feb 07

I had a good look at a friends MX22 Tx. today, it has servo's numbered up to #12, is it a 12 channel Tx ?

mick15

yes rob, but only in ppm mode

Thanks Mick, does the failsafe still operate in PPM mode ?

Rob,
I think it does with the Graupner RX but I'm sure Dave will correct me if I'm wrong, personally use mine with JR R1000 10channel PCM rx's , I dont need more (yet). I bought one from Dave two years ago after dumping my 9ZAP, am very happy I made the right choice even if I did have to replace 5 rx's as well, even the manual is pretty well too. Mike

Robrow

Sounds good Mike, I normally like to have a channel for each servo but my Rookie has 13 servo's so had to 'Y' the rudders (hate having to do that).

Looks like this Tx has a serious following, deservedly so from all the good reports.

Afaik the Graupner 12 channel PPM rx does not have DSP, in other words no failsafe. Multiplex synth 12 channel IPD rx, which do have failsafe, have a Graupner mode to let Graupner users get 12 channels with failsafe. Multiplex uses slight data compression to speed up the frame rate in 12 channel mode, and the synth rx can be set to Graupner mode so that the rx does not decompress the signal. As well as the rx you need to buy the PC connection cable and download the free Multiplex PC software since the choice of MPX, uni or Graupner mode can only be set via the PC.

Graupner's website has never mentioned DSP or failsafe in its pages for its 12 channel rx e.g. https://shop.graupner.de/webuerp/servlet/AI?ARTN=3163

rob it sounds to me you should be looking at a weatronic to go with your new mx22, when you get it!

I have an MX22 I am using here in the states ... love the European programming mixed with the Asian ergonomics. I have been a 10x user for more years than I care to admit, and think the MX22 is a real step ahead for a number of reasons.

I would like to try it with the IPD receiver, however. Do you have experience with this receiver, and how would you compare it in PPM 12 channel mode to a standard JR 10 channel setup in SPCM mode?

My Feedback: (1)

I have used nothing but IPD for the last 6 years in all my models, with the 12 channel versions in my jets. Performance has been superb. They have a built in battery backer and dual battery slots, and the synth versions have been independently tested to have phenomenal blocking of signals, or noisy ECU feedback, picked up on the servo cables.

I don't know how it compares to any of JRs PCM methods.

I don't use IPD because I think it is any better than PCM, but because I use a Multiplex tx and Multiplex stopped making PCM rx. So to get failsafe, I have to use their PPM IPD system, though like Graupner the 12 channel mode was always PPM only anyway. Having been forced to use IPD rather than PCM I have not had any regrets or felt it to be any less reliable or secure than PCM.

I also run this setup on my MC22 (same software as MX22). I ordered the RX set up for Graupner from the factory.
Only problem I have come across was when trying to use two Hitec digitals on a Y-lead,
none of the two would move.

Lars, this problem has occurred before with some Hitec digitals. The IPD data outputs from the chip are buffered which drops their voltage very slightly, some Hitec digitals have a very high threshold for detecting the high signal voltage and using two on a Y lead is just enough to drop the signal voltage just below the high threshold they use, hence the servos think they are seeing a permanently low voltage on the signal instead of seeing the alternating high and low voltage.

Guys

Late in this one, but the Gr/JR PPM Rx's don't have fail safe.
As Mick I always use the 10RS or 1000DS Rx's and I can always get enough functions with Y lead or match box
