Having issues on anything other than MANUAL
I have installed everything for my Ardupilot setup and am
having issues now using code 2.5.04. Therefore, I thought that I possibly had too much going on at once to test properly so I took out all but basic things for the Ardupilot. So I tried to fly my e* again and only had the Ardupilot, V2 shield, XYZ sensors, em406, XBee 900. When in manual everything is ok and has no issues. Once I turn on AUTO, FLY_BY_WIRE or STABLIZE the servos start glitching. By glitching I mean everything just goes haywire turning left right up down basically out of control. So I have now pulled the stuff out of the plane to try to do more testing with the equipment. The best I can think of is there maybe is some kind of RF interference going on somewhere.

On the board I have the black wires for the servo cables facing the outside on both connections to the board and have triple checked all other things I can in the wiki and still every time the servos are glitching. I also just tried briefly with the 2.6 code and still having the problem. My ESC did not come with a torrid on there could this be what is adding the issues? Also the other thing I have noticed is that once the ardu board is on anything other than manual the servos do not seem to have as much throw in them. I have tried to do the airframe test as I have seen that it has you test the radio and
servos for limits but I never have it ask me to move my sticks it just boots quickly and starts through the test. The last thing I notice is that occasionally after the ardu has been running for little bit the program I guess you could say hiccups. The data stream pauses come in even if using xbee’s or having the ftdi directly plugged in. It is not consistent and happens in all modes.

This link will show you the layout I used on my plane, it was a post I did before final assembly. If there are other pictures needed or you need to see any files please let me know and I will happily post them. Sorry for the long post just wanted to give as much info as I can and thanks for your help and time.

switch off the xbee 900 for starters.
next try with different ESC if you have a spare
Keep the receiver as far as possible from AP board.

I have already tried with xbees on and off. The only other ESC I have doesn't have a torrid on it either. But will give it a shot and I will try putting cable extenders on to get the rx further away as well. Thanks for your input Morli, hopefully that will get it straightened out though if its my RX I don't know where else to put it on my plane that would get it further apart than I have it on the board laid out.

lets not worry about where to put the rx now, do all servos glitch ? what radio, rx, what freq ?
If nothing else works then,
try with different radio(brands too , beg borrow steal ;-) ) some rx were known to have marginal signal quality which may or may not be reason.
try older ver of code ,flash it and see
BTW servo throws in stab mode looks very little but usually enough

yes both servos glitch. I have the futaba 7c 2.4 ghz as the manual says I pretty much have everything the manual says but the ublox i have the 406. The RX is futaba r617fs it was the ones that came with the radio.
And its not that it looks like they are moving a little its a ton and in the Ground Station software its as if the planes bouncing every where. Which is what it did in the air.
I have nothing outside of pure basics and recommended parts. I am going to make the video and get that posted maybe that will be easier for all.
Thanks :)

That's very strange. Any chance you upload a video of your servos glitching? I've never seen that....

Yeah I can try it just takes a long time to upload video I live in the boonies and only have dial up :) But I will make like a 30 sec clip and explain what is what in the video. Here is a picture of how its back to being laid out on my table. In the picture though I tried with the servo cables extended and moving the RX even further (still same outcome). Also I have tried doing this both indoors and out just in case.

"In the picture though I tried with the servo cables extended and moving the RX even further. Also I have tried doing this both indoors and out just in case." so what is the result? still glitching?

yes the 2.4ghz futaba 7c. Batteries are charging now they needed to be so I could do the videos.

Ok I uploaded a rar file of a few different videos showing different things. Each video is labeled as to what mode and Ardu version it's running. Each video and its labeling I hope is easy to figure out.
When playing the videos showing Ardu V. 2.5.4
You can see the video of the GS software in Manual mode here the servos do not move, only moving when the TX sticks are moved as they are suppose to so only posted to GS video as that shows what the software is seeing in Manual.
There is also a video of the Servos and GS software in fly by wire mode showing what I mean by the glitching.
When playing the videos showing Ardu V. 2.6
For this version I showed what the ground station software is showing for manual which you can see does not hold steady BUT the servos act as they should full throw and everything. But from viewing the software on manual with this version of code it holds the closest to stable on the software.
The video showing stabilize mode with 2.6 you can see how the servos are acting with everything sitting stable and nothing moving. There is also a corresponding video showing what the ground station software was displaying while the servos where twitching.
I have not flown with this code and just tried it today in hopes it would fix a bug or something. but the glitch I am seeing in 2.5.4 seems to be here as well but I dont think its software I think its something in my hardware setup.
When I had 2.5.4 up in the air and flipped on stabilize and AP my plane started acting pretty close to what you see the GS software showing. Now my understanding is stabilize and fly by wire are to basically just smooth things out and basically do what they say so I would assume sitting still they should not be trying to move as the servos are in manual mode. Or am I wrong in thinking this? Because it was acting the same in the air as it is on the ground. When it was in the air it would pitch side to side and up and down. Let me know what other info I can provide or anything else along those lines. Thanks for the help so far. - Attachments:

I can't download that video/rar, I'm afraid. (It's a lot easier if you can just upload to YouTube)
In the meantime, try upgrading to 2.6 here.
Here's a video of normal behavior (same RC as yours):
