That is an issue that has been known for quite a while. In dual path, instead of showing the signal strength for the remaining active antennas, disconnecting one of the receivers causes all antenna information to be lost. Since this issue has been around for a long time, I suspect it isn't easily fixed.

Hi looking for an opinion. I have a new jet which will need a receiver. I also have a 14 channel and 7 channel both new that I am thinking of using in dual path. This as opposed to buy a 200 with two 3 channel receivers.
My other planes do have the 200 system in them with no problems. How would this work out compared to using the 200 system.

Compared to the CB200 you will loose the short protection for each servos and will be using only one battery directly to the Rx so you will loose redundancy unless you set up an other system to feed the Rx with 2 batteries.
Telemetry wise with the CB200 you can plug up to 3 devices, with your system not sure what you will have I do not know which channel can be converted to telemetry on the R14

I have Jeti's DSM-10 which will control two Life battery's into the one switch. Other then the two battery problem which is solved with dsm 10 and the short protection what is the advantage. I wonder if using the 7 channel in with the 14 gives me the ability to use more devices?

My opinion:
Stan the servo protection isn't really that big of deal.. how many failures have we had that popped the polyfuse?..
The difference is in the antenna setup.. We went down this road a few years ago.. dual path vs default/clone. The 14 is just fine with the DSM10, as long as it isn't a big jet.. you are limited to burst 20 amps, 10 nominal.. just use multiplex plug directly into the 14.. Use good power wire
As far as dual path, vs clone, we have done both and I feel a lot better having my primary receiver talking to both transmitter modules, so I prefer default. Then you set up the 7 as a clone. set up the satellite port to monitor PPM.. I use signal weak to monitor it, so it tickles me if the clone receiver isn't outputting. it works fine.
However if you run dual path, it will also work fine..matter of preference..
That being said, over time, we have almost all switched the bigger and more complex jets to CB200/R3 setup because of the high speed redundancy..
I know Jim still has an R14/R5 setup that still works great in his reaction.
IF you are going to ever buddy box with another Jeti you have to run a default/R14/18 setup by the way..
So.. my answer is: It depends on the size, current, complexity, and composition.. and you can stack telemetry with the expanders.. I have had 6 things total plugged into one port so far

Goose, My new Jet is a Carf Viper. I am planning on either a JC 180 or a kt 210. 9 servos, 7955's. two of my other jets have cb 200's with R3's. I just had a 14 and 7 that I was not using. I guess I will use the CB 200. I agree that servo protection isn't high on my list either.
#2582
Stan, thats a no brainer.. CB200
If you haven't bought servos, take a hard look at the MKS servos too.. they have futuba splines. the 7955 equivalent is the 777 MKS. Both are heavy.. there are lighter ones more suited for the CARF Viper.

I need Help!!!! So I have a CB200 and 3 R3's all updated and confirmed. Servos I am using are JR8911's and MKS 777 x3 and MKS 1220 all HV. When everything is connected and turned on my rudder servo (MKS 777) is fluttering like crazy almost like trying to find the center. It moves from left to right like crazy. Now I also have a EX R12 that is up to date. I set up a new profile on my DS16 and used the R12 and the rudder was working correct with no jitter or crazy flutter. So I know its not the servo and I know its not the battery. I cleaned out my model with the CB200 in my DS16 created a new model and set up the R3's and CB200 correctly EXbus for both R3s dual path. and what do you know its start doing it again. I am lost and not sure why its doing it. The only thing that I can think of is that on the R12 not changing the servo assignments my rudders falls on channel 7 which is on of the PPM channels. If that is the case then how can I set the channel on the CB200 that the servo is in to PPM? I need help. this is making me loose my mind.

Okay I think I fixed it! not sure if this is how it supposed to be but it works and the rudder is smooth as butter now. Here is the video clip before and then after. This bellows my mind. I am not sure why I just cant hook it up all on the CB200.

Edit: Everything is hooked back up an man is it quite. not a buzz or anything. When sticks moved all movement is nice and smooth. Jeti Team Not sure why this happened but not sure if was just the servo that didn't like the CB200 or what but with it plugged into port 1 config to rudder on my R3 primary its works perfect.

Absolutely DO NOT FLY your airplane with the rudder servo attached directly to the R3. DISCONNECT that servo from the R3 IMMEDIATELY as connecting a high power servo to your R3 WILL DESTROY your CB200. The CB200 Sat and the first EXT port (non servo ports) are only capable of sourcing only 300ma of current and an MKS777 will regularly draw 10 times that much current and will burn out that Sat port the R3 is attached to.
Double check all your receiver settings.
Primary receiver to EX Bus, Fail-Safe Disabled.
Secondary receiver to EX Bus, Fail-Safe disabled.
Get rid of any strange output mapping from your R3s.
Set the CB200 output period to Auto if all servos are digital. Set fail-safe in CB200 ONLY.
Test it again.
What frame rate were you using in the R12/R3 when you tested the MKS with them. Were they set to the default 17ms ? If so, try reconnecting the servo to your R12 and set the R12's output period to Auto. If the servo then goes crazy when conncted to the R12, the servo isn't capable of handling the higher frame rate indicating it's defective. This seems rather unlikely but it's worth testing.
I've used MKS777 with a CB200 without the slightest hint of a problem.
If the servo still operates properly when connected to the R12 with output period set to Auto, does that servo act up in ALL CB200 ports ?
Do whatever trouble shooting you need in order to sort this out but don't fly with a servo connected to a CB200 remote receiver.

Hi Joe Jr
I think you issue with buzz is as wfield has pointed out that your frame rate is incorrect, set it to 17ms or perhaps auto in both the Sats/R3s, FS off then set 17ms-Auto in the CB200 (set any FS needed in CB200) and try again.
As Wified mentioned "please" dont run a hi powered servo from your sats/R3 output, you might get away with a std low power servo on a non critical function that dose not require FS
Another issue might be is that JR 8911 servos are defanatly not HV? There up to and not more than 6v, running HV will undoubtedly cause issues especially buzz.

Not sure where JoeJr1485 is located but here in the US we have the JR8911HV, which most of us simply refer to as JR8911s. The US version is HV rated and bit different than the JR8911 that is found in Europe, etc. I believe the European JR8911 is much closer to the US JR8711 servo which is as you mentioned, not HV rated.

Hi Wayne
Fair enough, Its all good intel, just wanted to be sure nobody blew there servos up on a misunderstanding

Thanks for helping me out. I will do that and triple check eveything. I hope I can get it to work properly. the main thing is I dont want to burn anything out. I'll report back soon. thanks again for helping me out.

If you can program to prevent that from happening ( i.e. in one drection only) then no problem...

Just a thought....So I would guess this would also work in reverse, i.e. when the throttle is lowered the flaps are deployed from 1/2 to full, this can be a dangerous situation... when I first started flying jets with a Boomerang I tried this thinking this would be a great idea...can you say slow down to snap!

For or a go around you could set the throttle activation higher. May 3/4 throttle. That should give a buffer area.

Okay so I have done everything that was instructed and it is still doing it. I took a video of my processes and you can see the results. I am lost. I still don't think its the servo or the extension wire because if that was the issue, it would have done the same thing on the 12 Channel. Please see video: https://www.youtube.com/watch?v=gJDP2_mQpc8. I wish there was PPM on the CB200 so that I could check that. Its also funny that none of the other servos are doing that not even the other 3 MKS servos I have. I also hooked up one of the flap servos to the rudder output and it worked fine so to me I would think that the rudder servo is defected but it cant be if it works fine on the RX12.
