What are you using for servo extensions?

  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.

  I'd like to ask if anyone knows if an analog servo would mask glitches
coming in?
  (2 - Futaba 3010's, 2 - Hitec HS77's, 1 - HS81MG)

  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.

  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.

  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.

  Now, my question again, are my analog servos just masking a problem, or is
this solely a problem in the digital servos?

  Thanks a ton everyone!

  Scott
