DX18's still browning out or is this a valid choice for our jets now?

Before I answer the OP’s question I would like to disagree with Zb/Jeti USA’s statement that, “The Jeti is far more superior to the DX18”.The jeti may have some things that are better than the DX18 but the DX18 has things that are better than the jetti, and no I’m not going to make a list that would be a poor use of space.
I currently own and fly a Futaba 18MZ, a Jeti Duplex DS-16, two Spektrum DX18s (one gen 1 and one gen 2), a JR 9503, a JR 12x, and a JR 28x and I like each and every one of these transmitters for different reasons. There is not one of them that I would call “far more superior”. Each transmitter is matched with the job I need it to do, nothing more.
Now to Pepperpete, I have been using the DX 18 gen 1&2 for quite a while now and have not had any trouble with them at all. If you do a quality install of your radio gear in your aircraft, your problems will be very few to none. Of course this statement applies to just about all of the current offerings today.

Yes, for a long time! Many pilots using the DX18 were previous JR 12x users, gladly dropping up to $1295 for that radio, only to find out the DX18 beat it hands down in programming and features for less than $800. You won't find many DX18 users swapping to the crazy priced 28X or even lower priced JR's that aren't backward compatible either! Many, like me, feel JR screwed the pooch (dropped the ball, insert your own analogy here) in the radio market...

Would not be the first time an engineer design something they had no first person experience with! I deal with that every day at my job.
The word on the street is the voice module is going to be programmable. So...having your TX call your maneuvers for you may be in the future. Something I know many would like to have.

I just did the switch to Jeti from dx18. All my future setup will be jeti ds16 for the time being . Nothing wrong with the dx18 radio its self other than a few satilites go bad, along with the occational bind being lost, & the satilite cable not making good cotact. Things that sould not happen at all. Correct me if im wrong but theres less servo resolution on the expander box.

They fixed the slow reboot five years ago with quick connect. The AR8000 and later receivers operate to low voltage levels similar to other brands. It was only the first series of DSM2 receivers that needed higher minimum voltage and had slower recovery times.

Sorry I cant agree on that note. Just last week my buddy had a crash of his goblin 380 heli with DSMX satilites and a skookum 720 with logging.
Skookum showed a loss of signal yet stayed online throughout the crash. Turns out the new BK servos he was using was browning out the satellites from the voltage drops associated with heavy servo cycles. Solved it with a better BEC, but I was surprised to see the DSMX sats be the first to drop out.

That would not be legal in most competitions. Although I am not an IMAC, pattern guy. I fly scale. It is nice to read all of these posts about the DX 18 from the Jet guys. If you can trust it, then pretty much anyone can. The data logging point is an important one. And being that is completely new to me, something I will be looking into and using.

I agree, but the fact that all the remaining electronics (skookum, castle speed controller) were able to survive the brownout but not the DSMX sats tells me I won't be flying one on anything more than a $100 foamy.
A futaba reciever will stay online to a voltage the servos will stop driving.
And yes I know futaba had heat problems shutdowns a few years ago, but that seems solved now as I thought the brownout problem with the had been with spectrum.

Ron, you haven't even used the radio yet!! I have used Futaba, JR and Spektrum over the past 30 years. For the last 2 years a DX18 gen 1, I love it, as it is simple to program, works great and is affordable. I can't see spending $2700 on a radio when my $ 760 dollar one does everything I need and more. That being said all these manufacturers make good products and any one of them can have a bad component now and then. It comes down to what suits you.

pete , get back to us when you've had time to use one. i'm telling you , they are amazing . pete , you have some really nice ,high end aircraft .. why should the price bother you? i would think someone with that kind of investment would appreciate the effort that JR has spent on this radio. If the 18 works for you then enjoy it but don't forget about the guys flying a radio like the DX6 saying ,"i'd never spend 800.00 on a radio" . what i'm saying is , everything has a cost. BTW we are having are informal Jet together in july and you and your friends are more than welcome to come down . it's july 18-19. We have an awesome place to fly. WB_1

Pretty sure if memory serves JR makes Spektrum for HH, correct me if Im wrong. The product line provides different features and price points for HH. Just like other major brands they make another product line because not everyone likes the primary brand. Oakley for instance makes Dragon eyewear.
I know the menu structure on the lower channel Spektrum models is derived from the JR 9303 menu which was very easy to navigate. The DX18 has some functionality like that from what I could see so far. Ive had mine out of the box twice, not much time to mess with it yet.
My main reasons for the purchase were a) product support b) JR compatibility since I have a lot of equipment c) 18 channels d) built in sequencer e) price $729 with extra free 9ch Rx
I'm disappointed JR 's product line jumps over from the 11X past the teens and into a $2800 28 channel radio. Thats pretty strange and a lapse of customer support. I would have bought a $1000 16-18Ch JR radio if I could but instead Im trying out the DX18.
Until Jeti is more common and proven in the US I have no interest in the system. I have an investment in JR/Spektrum with a perfect track record for 10+ years, amazingly. Plus, Im not a fan of removable switches and more points of failure either on the Tx or in the plane.
