<DIV><FONT face=Arial size=2>OK, is any of the analog servos? Do the
digitals also do it? (I assume not). For example, I've noticed
that JR 4721 and 4131 servos have a cyclic response to most any JR digital
installed on the same receiver. Everything worked fine from a
reliability/range standpoint, but there was this small, regular interval "blit";
just a couple of degrees of movement from whatever position the analog
servo should have been remaining in. The digitals were rock solid, the
4131 and 4721 just blitted a little bit. I finally decided that I just
wouldn't mix the 4131 or 4721 in a digital servo environment and that was the
end of it.</FONT></DIV>

maybe tommorow. While range checking the digis if I put my hand on the
antenna the glitch increased but with the analog there was no glitch at all.
My father and I have been working this problem for over a month we have
replaced everything or sent it in to be checked.Right now no glitches with
analogs but again will the glitch present itself as noticably with analogs
as apose to the digis.We have no glitch right now but still no confidence in

<DIV><SPAN>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. <BR><BR>

<DIV><SPAN><FONT face=Arial color=#0000ff 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>

Servo RF Masking and....Thanks!<BR><BR></FONT></DIV></SPAN></DIV>
<DIV><SPAN>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>
