not sure why JR would design and allow operating temps that high on critical components. we all know heat kills components life span faster then anything. id be afraid of using that here in a florida summer.

HI Jeff,
thanks for verifying!
I swapped out receivers with same result. tried different servos, etc.
I feel better with you double checking
thanks

Transmitters create heat. many small wattage video transmitters even have a fan.
While you might not think it is a transmitter..... it is. it is actually called a transceiver. the Telemetry functions and the transmitter back to the TX are built into every JR DMSS RX. unlike others that use a separate module.
Even the FCC filings for the JR DMSS RX's list them as transceivers.

Absolutely, I love JR equipment but I also use Futuba and others. The Futaba R7008 and R7003 (also transceivers) also draw a quiescent current (no loads attached.. sensors etc.) of approximately 200ma. A interesting point of note, the older receivers without telemetry (without transmitter and therefore not a transceiver) also draw around 200ma - evolution and efficiency improvements in electronics.

What a waste of time and money.
First JR leave their customers waiting for 2.4 then hang their customers out to dry with no DSM etc compatibility, then come up with an old tek alumin case, no voice capability, just some cheesy and useless flight graphics. They are so far behind the cheapies like FRSky its sad.
I bought JR for the quality etc 10 yers ago and have not felt my loyalty at all rewarded, in fact the opposite.
one lost customer.

Sorry to hear that. But (litany of cliche responses) "To each there own" and "Opinions are like @$$#)!#$, everybody has one" Now the serious response, like I mentioned in earlier posts, I'm brand agnostic, I have and use most of the top line radios by Futaba, Skektrum, Jeti, JR and Graupner. I find the 28X to be an awesome hardware platform and has resolution and precision well beyond anything else on the market.. overkill? We'll see. But of course that kind of resolution probably wouldn't be noticeable to somebody who's happy with the lower end "Cheapie" transmitters and flying $200 foamies. Not to sound like a snob, I fly foamies sometimes too. Bottom line, I think the hardware is revolutionary. As for backwards compatibility, sometimes it has to be sacrificed to make revolutionary advancements in a technology... which is what I believe JR has done with this Radio. As for the software, that will be an evolutionary process. It's pretty nice already, I'm sure that they'll beef up the weak points in good time.

i voiced the same opinion to JR. they should have had an exit strategy agreement with spektrum . I had a perfect condition 12x that i was forced to sell because i couldn't get JR DSMX receivers. I refuse to run any spektrum receivers in anything i fly , period ..
It was a good thing in the end.. i jumped into the new DMSS platform and i think it's going to workout great. though dropping 2,700 on a r/c radio was no my first choice , i think it will be worth in it the end. i know spektrum has some bells and whistles like a in depth voice system they lack more important things that JR makes up for like non shared channels and xbus. I'm a JR guy and probably will be for a long time. WB_1

Why would a manufacturer want to set their equipment up to be compatible with a competitors equipment? That makes no sense.

It's about time JR have their own system. I have always used JR and always will as I have never had a failure with JR equipment at all in 18 years. The only 2 failures I've had was with other brands. I'm 100% JR and I'll gladly pay for that kind of reliability.

It's amazing how many complain about prices of upper brand names just because they are brand names. At the end of the day, everyone has a choice.

I must have my head in the sand, so what makes you say that about Spektrum receivers.

I have been using Spektrum receivers with my JR transmitter. So i have quite a combination of Spektrum and JR receivers.
While the Spektrum receivers work fine with the JR transmitter. How about a JR receiver working with a Spektrum transmitter? May seem like a silly question but stranger things have happened.......

Default Battery Drain Issue

I got my 28x just before leaving for a week's vacation. I fully charged it when I got it, then played around with it some for programming, etc. Battery was nowhere near depleted. Just turned it on again after about 8 days of being powered off. It started beeping immediately and booted up far enough to say battery was critically low. Has anyone else experienced this kind of battery drain?

I just got back from the not so local LHS and they had quite a few 28x's in stock. He pulled out the demo model, but then we couldn't get it to turn on at all.... he suggested it might have a flat battery. can't have been sitting on the shelf for that long, and no models would have been setup with it so????

Anyways, quite surprised just how heavy it was!! I'd guess that it's weight would have been about x2 to x3 times the weight of the XG14. I really like the nice and lightweight feel of the XG14...

Thanks

no battery issues here. but i haven't let mine sit that long. when i got mine it had a decent charge in it and i used it a little before i opted to put a good charge in it. i had the same issue with a brand new DX6 with the li-po battery upgrade. On a side note... i get pretty good time on my battery . i'm setting up my bron corsair and i've had it on a lot. i think i've charged like 3 times so far.

pete , we've been using Spek receivers with JR for years and vice versa . As far a spek receivers go. For me i choose not to use them. That's why i went DMSS. it's all in what works for you and personal preference.

My 28X weighs 1288 grams and my 12X weighs 1029 grams. I like my Tx's to have a heavy feel.

yeah don't understand that.. I know a guy who bought a XG14 and then sold it straight away because he said it was too light?? People think weight=worth... It's aviation, not gold! Weight is the enemy of aviation. I wonder of people buy old iPads becuase they weigh more than the new ones?

anyways, it's a heavy radio. Rant over.

thanks

Nothing to do with weight = worth. It's personal preference.

Plastic is light. Aluminum is more heavy.
Plastic is cheap. Aluminum is more expensive.

i did the same thing for the same reason. i like heavy radios. it's hard to go from a 12X to a 14 . the XG 14 is a sport radio .That being said , it's still a great radio. the deal breaker for me was the screen size. it forced them to break menus up into several screens /parts on several screens. i wish they could make an in between radio because of the cost issue. i love the XG11 screen and menu layout but i just can't get it to feel right in my hands because of the large battery cover or i would have bought one. the 28X feels just right in my hands and comfort is everything when your landing a turbine or a warbird you've worked on for 2 years.

Been out this morning with my 28X, three flights in my Xcalibur were all as expected. Using twin Tx packs, so max weight and its not an issue even without a neck strap that none of my circle of friends use.

dave, would you mind sharing the twin pack battery setup as well as the receiver your using? thanks, WB_1

Where did you get the second battery? I can't find them available yet.

Jeremy

Update - Never mind I found it - same as the one for the XG14E

This is flying the same set up I had with my XG-11, so its an 1131B
I pushed the UK JR distributor to order additional batteries with the first order of radios, I ordered one for each of my delivery as I expected everyone to have one!

Dave
Yes-14E pack!
