JR/ Graupner MX22
 

While my PCM10X is at Horizon for repair, I was contemplating possibly replacing it. I know there is the Spread Spectrum revolution comming in the next year or so, so hopefully my 10X can soldier on until then, but just in case, I was looking at potentially another 10X or the JR/ Graupner MX-22. 10 channels in SPCM or 12 in PPM. Same case as the 9X but with unique Graupner software and more capabilities than the 10X, incuding switch assignability and smooth flight mode transitions.

Anyone in the US using the MX-22?

The only US imported seems to be Modellbau-usa, and I'm not sure of what technical support would be available here in the US. Horizon Hobby support for JR is fantastic, but if the JR/ Graupner stuff has to go back to Germany then I may not be so keen. In the UK and Europe the MX-22 and the other Graupner products seem extremely popular, but are virtually unknown in the US. It seems the siilar price in the US as to importing it from the UK.

I am not considering a switch to a non JR compatible system at this time.

Thanks

Hi Paul, the mx Tx is reviewed in the new RCJI mag,don,t know if youve
seen it .
Part 1 in this issue and part 2 in the next.

RE: JR/ Graupner MX22
 

Thanks Maverick2005, I've read the first part of the review, that is what pointed me to search out a distributor in the US. I might call them in the week and see what repair service Modellbau-usa can offer.

Still waiting on news about my broken 10X.

I've got one and like it. It'll do everything but beg for peanuts. It does take a bit of learning, but once you get the hang of the programing it's a very flexable radio. Mine will run 12 channels if you can find and RX with that many (multiplex).

RE: JR/ Graupner MX22
 

Whilst Graupner does make a 12 channel rx for the mx-22, it has no failsafe which seems rather pointless on the sort of models in which you are likely to want to use 12 channels. The only way you can have 12 channels and failsafe is to use the Multiplex IPD synth rx with the PC connect cable and the free PC software from Multiplex. The synth rx can be set from PC to run in Graupner rather than in Multiplex mode (Multiplex uses data compression to speed up the refresh rate, Graupner does not), and the IPD rx gives you fully programmable failsafe on all 12 channels which works with any brand of tx.

There's one for sale on RCU market. I have one myself also (MC-24) that I purchased from Johnny H as well. Wouldn't trade it for anything out there, this radio has so many unique features I only waiting for them to come out with the spread spectrum mode so I can upgrade. That's the beauty of Graupner, you can always add anything you want to them and customize everything on them.

RE: JR/ Graupner MX22
 

Hmm, there are some very powerful and capable Txs at this end of the market, what does the MC24 have that is unique?

RE: JR/ Graupner MX22
 

Hmm... I want to buy a MC-24 but I was VERY surprised to find that it has no digital trims. This is stupid! You have to store in memory the trims after landing.

I own two MX-22 and I can't imagine one thing this transmitter can't do. I've been using this transmitter for over two years and all I can say is GREAT!! Even his little brother MX-12 (6ch, ~$200) has ADT (advanced digital trims).

Can you upgrade it (MC-24) with this little ADT feature? Don't think so...
Maybe I'm wrong about this. In this case I'll buy one tomorrow.

RE: JR/ Graupner MX22
 

Lucian,

the Tx I have (not an MC-24) does not have digital trims and I think that is an advantage in its favour. I don't like digital trims at all. I don't regard mechanical trims on the MC-24 as a bad thing, I prefer them!

RE: JR/ Graupner MX22
 

Has Graupner announced a spread spectrum radio?

RE: JR/ Graupner MX22
 

Harry,
I totally agree with you. Can someone expalin the reason for digital trims? I was asked to test fly a model with a Futaba FF9, all digital trims. The model was seriously out of trim in all 3 axies (never had that before and I hope never to encounter it again). What a ball ache the s**ing digital trims were. I nearly planted it half a dozen times before I got it trimmed out. With analogue trims it would have been done in a few seconds.
Regards,

John

RE: JR/ Graupner MX22
 

How can you trim the model for each flight phase? And keep those trims in Tx memory too.
I'm just curious...
You're right John. If the model is out of trim too much it's not so easy (for a beginner in digital trims) to keep the plane in the air and trim it in the same time. But after some time you will find this very easy.

RE: JR/ Graupner MX22
 

I have used the MX-22 for 3 years now, and I wouldn't go back to analog trim. I think it's a matter of getting used to the digital trim. I maidened a plane for a friend and his transmitter had analog trims that I almost couldn't find with my big fingers[&o], because the trims were almost flush with the top skin of the transmitter. In the end I thinks it's a good thing that they make different kinds of transmitters. Some like handheld tx with digital trim and others don't. I love my MX-22. It's the best tx I ever had.

RE: JR/ Graupner MX22
 

I have been using a JR 10x for 5 years now and also have used a MX 22 aswell for the past 18 months. two excellent radios, but i would have to say i prefer the software in the MX 22. Predominantly the 10X i use strictly for Jet flying and pattern aircraft. The 10X is the re-nowned choice by jet pilots as we all know and suits the needs of any jet modeller with ease of mixing etc. Have just started flying jets now on the MX 22. What can i say. With programming of flight modes easier than the 10X, assigning channels to switches done with the press of a button it does make programming the most complicated jet model quite easier once the use4r becomes familiar with the software. 10x is fantastic, if you want more "at your finger tip" programming versatility the MX 22 is the go. i do prefer the MX 22 by far.
just my 10 cents worth.

RE: JR/ Graupner MX22
 

Hi Lucian,
Rather easily if you use a Multiplex 4000! It notes the trim position in each flight mode despite the physical trim position. When you switch on, if the trims are not in the last used position, the TX won't let you go further until you have repositioned the trims correctly. Of course you can electronically reset the trims for each model, but it is usually better to do it mechanically, and this feature reminds me when I forget.
For me digital trims are an unwelcome development and there is a better way.

John

Hi gang,

Well been sales rep for Modellbau - USA, I'll have to chip in. We at modellbau -USA give small technical support to radio systems. Switch maintenance, programing, batteries and backups and such on. When something mayor happens to your mx 22 or mc 24, we have to send it back to Germany. The key here is that every Graupner radio comes with a 2 year warranty. On my experience, the only way to mess up badly one of this radios, is either charging with bad charging cables (shortcircuits) or dropping the radio itself into the asphalt . Don't ask me how I know this, it hurt! Anyway, back on subject, if anyone has any question related i'll be glad to help my best

I have just got myself a mx 22, the manual that came with it is in german, is there a english version avaiable?

RE: JR/ Graupner MX22
 

Mart

Yes, Sorry it should have been English-contact me and i'll send one out.

Best Regards

Thanks dave i will ring you.

Hi Mick, yes getting to find my way round but needed to apply a mix on three way switch to use for flaps pluss add some down elevator, has me stumped at the moment.

RE: JR/ Graupner MX22
 

I have been flying the JR 10X for years and have been extremely satisfied. I have test flown a couple of aircraft here in the US that TamJets have built for Ali Machinchy of Als hobbies on a 10X, then sent him the program via email when we ship the plane. Everytime I ask him about the setup, he tells me that he uses the 10X program for the control throws and trim but immediately transfers the aircraft to his Graupner MX-22 before he fly's. So I became curious, about the radio that is being flown by a highly respected pilot, as to its advantages. Graupner has a fantastic reputation, and after finding out how great the software is, I decided to purchase one from alshobbies.com in the UK. Even though Als hobbies is across the pond, their reputation for customer support is second to none, and I have no doubt that any innitial setup questions will be promptly answered. It helps that Ali is a very experienced pilot who has used this radio on countless complex aircraft, something very important when I look for a dealer to buy from. I will be installing this radio in my SuperHornet with a Weatronics RX, and I am excited to add a few functions to the aircraft that I cant do with the 10X.

Dave,
What sort of shipping charges would there be on a MX-22 to the US, Ohio to be specific?
I imagine my synthesised module would plug right in?

Bob Belluomini

RE: JR/ Graupner MX22
 

Bob

email me at [email protected] and I'll sort you a price.
Yes the 72mHz module plugs straight in.

I have the oldest MX-22 (with English software) in the world (there is still a mistake in the programming which goes back to German on certain functions!!)
I have another MX-22 I've been using for three years, its a great radio and I'm glad I introduced so many UK pilots to it. Many of the Motors & Rotors team fly with the MX-22.
Graupner have announced the MX-24 which will be a 12 channel version (on PCM too!) with internal frequency PLL options. No 72mHz is due yet, but I have spoken to Graupner about this for a future date. Guys at Florida Jets can talk with Graupner about this as they are sending a "crack" team this year.

Dave

RE: JR/ Graupner MX22
 

Guys for those that are interested. I am just in the process of shipping some big crates to Florida jets, and I have space for some MX-22's next to Strawboss's Set, so I guess if you are quick I could orgainse a special shipping rate of..... Free ;) All you would have to do is cover the costs of shipping within the USA.
Or you can come and see me in the Graupner tent at Florida jets..

RE: JR/ Graupner MX22
 

Hi guys,
theres a smart case available for your MX22 to keep it nice, and its already cut out, Just pop it in :) Just waiting for some nice dry weather now to try out my new tranny ;)
