<DIV><FONT face=Arial size=2>I have seen this kind of "Twilight Zone" ( I really
like that term!) failure in industrial products. The problem is probably present
in the Analog setup but the system is not fast enough for it to
show.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If the digital servos are trying to latch up on the
leading edge of a signal shift they may simply be following switching
transients.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I seem to recall a condition where Jr had a filter
across the signal at the reciever and Futaba had a filter across the signal at
the servo. Since it always seemed to work OK so the condition was ignored.
May be that the filter has become essential. I suppose that we may have reached
the point in time that we can no longer ignore the differences in the two
systems. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have used mixed systems but I have never been
comfortable ignoring any engineer's specfications.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When you mix the two systems it is a hack and you
become the test pilot...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>BTW, my guess is that the glitch can be fixed with
a capacitor (100pf?) across the signal at the servo end. But then it might
just make it worse!</FONT></DIV>

size=2>Scott A.: Yeah, a possibility - but he says it works OK with the analog
servos. It would be worth checking, but if he has another Rx he could just
substitute that (probably already did) and see if the problem goes away. Scott
P.: Does moving the antenna change anything? You have to find the common
denominator. If it's not the Rx then maybe it has something to do with the
installation. There is something going on there and I'm not sure why the
digital servos make it more apparent. Find someone who knows how to use a
'scope and see if they can help you. This is weird - you guys have the same
first name and my last name looks like yours. Maybe we're all stuck in the
Twilight Zone...</FONT></SPAN></DIV>

<DIV><FONT face=Arial color=#0000ff size=4>Stupid question, did you send RX
out and have it put on a shaker table and checked.. I had a RX issue for
over a month and spent time with Tony S. and he found a bad filter on the
board.. </FONT></DIV>
