I agree that this is mostly a theoretical exercise because we will never notice the differences past the point things are reliable for us. For example there is no way that any of us can make use of 4096 steps of resolution when our digital servos max out at 1024 steps. However Jeti, DMSS, and FASSTEST all support this. So DSMX and FASST being limited to 1024/2048 steps isn't a limitation for any of us. DMSS's 64bit Guid is way over the top for model id's, but it is larger than anyone else's and in a theoretical comparison they have bragging rights for this.

Really good info
The Jeti system is close to the perfect system that I have always wished existed. Well, as perfect as can be. The programming is so overwhelming, that if you cannot program it, you probably don't need it.
I definitely agree on the order of the systems. One thing I noticed is that with the redundant receivers one has the choice of just the receiver, or using another receiver as a satellite. Is this correct? I still use my JR 12x for the BNF stuff. I did have several "brown-outs" with a Trex 450 with the smaller receivers, but that is another story. Never did figure it out. I also had a failure with an older 8 channel Futaba receiver on the FASST system with a Kinetic 50. Other than those problems, I have been pretty impressed with the 2.4 systems. Does anyone know of anyone that uses the Jeti system with turbine jet systems? I would think this would be a great testament to the rang of the Jeti system?

I fly two Bergen 44 Magnum turbine Helicopters on Jeti. One with a Vbar and the other with a Skookum 540.

I've flown Jeti on my turbine heli since day 1 and have been flying it on my Goblin since I received my DC-16 and RX's back in January. I'm also running Jeti on my one and only plane. I've taken the plane as high as I could go comfortably (it was a tiny speck) and didn't have a single issue.
There are several guys over in Europe flying Jeti on turbines. They use multiple receivers for redundant signal paths and any possible RF blocking depending on orientation but I haven't heard of any issues. I have heard of glider pilots getting "weak signal" warnings from the Jeti when they're flying *really* high-- but the weak signal warning from the TX is only a warning regarding the strength of the received telemetry stream from the RX to the TX; the RX's telemetry broadcast power is at a much lower power than the TX broadcast power. I have about 60 hours of flight time now on my DC16 between all my models and haven't had a single issue of glitching, loss of signal, lockouts, or weak signal alerts. The system feels very "connected" with no perceptible lag and it's easily the best TX I've ever used from a quality, programming, versatility, and "feel" standpoint.

Thank you for all the replies. It is apparent that there are many enthusiastic pilots that are having great success with this system. I have a feeling I may pull the trigger on this system in the near future.

What's the transmitter power on the Jeti?

I may be wrong, but don't most manufacturers try to run pretty close the maximum allowed transmission power?
I think a bigger issue is the error correction scheme used when the signal is near its limits.

I'll let Danny or ZB respond to the range, but I can tell you I saw an article that tested range and Jeti was second in distance coming in at, I think, around 5 miles. Surely far enough for any heli pilot.
I'd also think this is far enough for any fpv pilots who are flying within the AMA safety guidelines. I'd also be surprised if video feeds can have the same range given existing technology. Lou

JETI Signal Specs Vs. Futaba Vs. Spektrum???
Would love to see a range test similar to this on the various systems... Jeti included (obviously).

Found this Jeti vs Futaba vid. Not a lot of detail here though. Also, posted in 2008.

Correct; however, the maximum allowed power is significantly higher in the US (247) versus requirements for EU (328) and for France. I wondered whether Jeti uniformly adopted the lower power standard or has a special version for the US market.

Max output power for the DS-16 is approx 20dBm

The DC-16 does have a "French mode" option in the software. I suppose it's an "on your honor" thing for pilots in France to decrease their power level.

Re: JETI Signal Specs Vs. Futaba Vs. Spektrum???
Does any one run the jeti rx in ppm (single line) output mode with vbar? Id like to hear your experience. Does the 20ms ppm mode introduces any noticeable lag compared to say Futaba S-bus?

"We have added the possibility to set 10ms frame rate. In System → Configuration set the option “Transmit frequency” to 100Hz. Please note that if you really want to take advantage mode is available for all receivers, also with firmware version lesser than 3.10."of the 10ms frame rate, you should check the receiver’s settings as well and confirm that the output period is set to “Auto” or “By Transmitter” and you are using only servo-groups A thru C. This should result in fast and very smooth reactions of your digital servos. The 10ms I doubt you could feel a difference between 8ms, 10ms, 11ms frame rates. However you can feel a difference when the transmitter's CPU gets bogged down.
