Few Pictures of Jeti Central Box 210 and 220, you can check the pdf. for details.
Main difference is CB210 no poly-fuses, CB220 11 Standard + 4 HD servo protection.
Prices very similar, CB220 should be only $20.00 more expensive than CB210

plastic case versus those fancy aluminum one....I have several in my jets...they work great.

The CB200 is a good product, I have several of them in service.
The only thing to consider is the fact that the CB200 uses polyfuses on the servo power outputs. These are similar to physical fuses in that they open when too much current is passed through them, but unlike physical fuses, they close again when they recover. They are tripped by heating, and once open, the source of heating stops and they re-close. If you are curious, see: https://en.wikipedia.org/wiki/Resettable_fuse
The idea is that a shorted servo does not take down the power supply to the entire aircraft, a laudable goal. The issue is that with very large jets or large 3D aerobatic airplanes, the approx 4A trip points of the polyfuses could be hit in extreme flight operations (e.g. flaps full on large jet at too high a speed, huge aileron or elevator deflections in 3D birds).
I've made measurements on the CB200's polyfuses and find that they take a current a little beyond 4A applied for 10s of seconds before they open. You can get close to this on the flaps for example on an Ultra Bandit with full flaps put down at a little too high a speed .. I've got the measurements for this (!) .. and they polyfuses did not pop. But if they had it is likely on flap would "pop" before the other which could be a problem...
So I think it's safe to say that for most of us, this is not likely a concern .. just something to be aware of. I first noticed this when Jeti published update notes on the CB 200 that suggested it would be appropriate to parallel the power and ground (NOT the signal!) wires from two outputs of the CB200 for possible high-draw situations.
I really appreciate Jeti making us aware of this in the release notes and applaud them for giving us a choice in the new central box.
For my larger planes, I use a CB400 but don't use its servo power outputs (red and black wires to servos) for possible high-draw surfaces directly .. I supply power from another source (e.g. the BEC on the CB400) to avoid this risk.
As you have seen, Jeti will have an option for polyfuses or not on the new CB which is really great .. then we can make a choice based on the requirements of a particular install.

Thank you Dave for your interesting contribution.
So, I guess that the new CB210 has no polyfuses, so it has no overload protection in case of stuck servo or elec short ?

I can see on Hacker Motor GmbH Facebook that it is a new Jeti DC-16 (color display, backup 900 MHz etc) coming (in January 2020), that is shown this weekend (Nov 1-3) at Faszination Modellbau in Friedrichshafen, Germany. If and when it will be in US I'm sure Zb/Jeti USA can tell.
Some info already at "jetiforum", some person that visited Faszination Modellbau and have seen the "new" radio posted here:

Will be building an SS as well soon....and I will be using a CB200, they never let me down and I have never trip any poly fuse....only a bad setup could do that....using the MKS380 on the flaps and Rudder....MKS599 for ailerons and elevator with a MKS 550 on steering...if out I might do a 220...just because it’s pretty.....but the 200 will work just fine as it’s working in all my jets

Excellent choice all the way around! I have 9930’s in my large Havoc and really like them. All control surfaces except flaps, where I have HBL599’s. Noticeably smoother than 777A+’s that I’ve used in the past before learning about the 9930’s. CB200 and Cortex Pro. Great setup!
Be sure to use high quality wire such as PowerBox Maxi Wire.

I've used the CB200 on an ultra bandit with a merlin 200XBL, and a large (not the new giant one..) skymaster Viperjet with the same 200 merlin .. no probs on either. over many many flights I think the Havoc SS would be just fine with the CB200. The big havoc I'd give some more thought.
Yes a bad setup (poor mech advantage) could create a problem .. but hey .. we have telemetry on the Jetis .. just look at the total current draw in some of your flights and decide for yourself .. even if not monitoring individual servos, you can see the current draw from flaps going down. I have a verbal warning when either battery current from the CBs goes over 4A total .. and I get it now and then .. but this is over all surfaces ... not that any one of them is over 4A.
And I really like the fact that Jeti is giving us a choice .. to have polyfuses or not .. the new one with polyfuses says it has some outputs for high current and some for normal. Kudos to Jeti ... we can pick what we need for a given install.

I’ve had no issues at all on a T-3 and my current large Havoc. Flaps are setup so that servo arm is pointed straight at flap when at full flaps. You can put pressure on the flaps with your hand to simulate wind and there are no servo amps drawn ... mechanically locked. It’s also important to ensure you are not pulling amps when flaps are up.
I keep a close eye on my amp usage and it’s all good. Love the data logging capability of Jeti!
I would not want to have a setup where you’re relying on the servo power to hold full flaps.

Has anyone seen this error? I've tried re-seating the cable that connects the switches/levers on the back panel but I keep getting this error pretty frequently. If I click on OK my switches SA and SB don't work, which control my Retracts and Flaps. This issue has been on-going since I got my DS-24 about a year ago, but it has recently started happening much more frequently and it's also becoming more and more difficult to resolve. E.g. this past Sunday at the field it took me 15 minutes of turning it on and off to get it recognize the switches and operate correctly, needless to say after all that I decided it was not safe to fly until I got this sorted out. I'm really interested in pre-ordering a DS-12 for my Helicopters but this issue is making me think I might be better off just keeping my DX-18. Any help would be greatly appreciated, thanks. - Tom

Talked with James on the phone, after describing the issue he suggested I send it to him, so I mailed it out yesterday. He did say that he has never seen this type of error but feels like it might be a bad switch on the back panel. Fingers crossed it’s something simple.

As some of you might know there will be Gen 2 of Jeti DC-16 Radio System coming up early next year, and we know that market for tray style radios in North/South Americas is very small. Would be even anybody interested in this kind of product?
