I've literally tried EVERYTHING possible to isolate the problem. The only problem I can find is solely in the servos. The battery is bran new (duralite 2s2p), bran new heavy duty MPI switch. I can reproduce the problem with the digis with many different switch/battery/regulator set ups. I know current draw isn't a problem as I've flown this set up for 2 years with no faults.

<div><span><font color="#0000ff" face="Arial" size="2"> Well I'm sure you've been through a lot already, but what you need
to do is try to isolate the problem if possible. Start with a working setup (the
analog servos). Next, add 1 digital servo. If it still works, remove that servo
and try another. Only change ONE thing at a time. If it works with 1 digital
servo ALL THE TIME, then add a second one. If you start to see problems as you
add more digital servos (i.e gets worse with 3 or 4 digital servos but seems to
work OK with 1 or 2), look at your battery and switch. What are you using for a
battery and switch by the way? If your radio checks out OK (RF-wise) it's more
likely that there is a problem with power. I bet you didn't have Rx the
batteries checked did you? As you know, analog servos don't draw nearly as much
current as digital servos. That could be the problem. If you have any way to
look at the voltage when all of this is happening it could reveal some things.
One way to do this is to put a servo lead in an unused channel on the Rx,
connect it to a voltmeter, turn everything on and move the sticks. Don't
use an Expanded-scale volt meter, just a plain old DVM (or better yet an analog
volt meter) will do. See what that tells you.</font></span></div></div><div><span class="sg">

and....Thanks!<br><br></font></div></span></div><div><span class="e" id="q_10c3b66bae3755dc_4">First I would like to thank everyone for
the great advice on these last few posts I've posted. Everyone has been a big
help.<br><br>I'd like to ask if anyone knows if an analog servo would mask
glitches coming in?<br>(2 - Futaba 3010's, 2 - Hitec HS77's, 1 - HS81MG)
<br><br>When I connect my JR digital servos ( 2 - 9411sa's, 1 - 8411sa, 1 -
8417, 1 - 3421sa) I get a pretty significant, constant glitch, as if the
servos are constantly trying to center, but they have no load what so ever.
This is the problem I have described in previous posts. <br><br>When I connect
analog servos in an identical set up, there is no "noise" at all. I range
tested them at 100 feet with 1 antenna section up and there is no loss in
speed and no sluggish behavior. I also range tested this at about 300 feet
with the antenna completely down just for kicks, and I get the same results.
<br><br>When I range test the digital servos, even at the 100 foot range with
the antenna completely extended there is a significant, constant glitch. The
servos, receiver, and transmitter have all just gotten back from being checked
and the 9411sa's had new pots put in, the receiver had been re-tuned to the
frequency, and the transmitter got a new antenna. I am very surprised with
these results as I just spent a fair amount of money to have my electronics
looked at and deemed well. <br><br>Now, my question again, are my analog
servos just masking a problem, or is this solely a problem in the digital
servos?<br><br>Thanks a ton
everyone!<br><br>Scott<br></span></div><div></div>
