Twitch on servos??

Hi ALL! I have a bit of a problem with my APM2,5. There is a unexplained twitch on the servos, On manual mode not touching the plane or radio the ailerons elevator and rudder will twitch, sometimes violently also when you move the aileron For instance the rudder will twitch and so on the problem seems worse near the midpoint of the sticks on my radio.I have 2.7 firmware and calibrated the radio did the whole setup,I removed everything that i thought could cause interference but it is still there.I changed my reserver .....same problem got a different APM 2.5....same problem radio works fine all is fine when  use my Apm1.4.I use a Futaba T8J

Any advice Please?

    Thanks for the feedback,tried all your suggestions but the problem remains.

    Will go for digital servos maybe that helps....

    Thanks for all the input!

    Most servo cable issue. I had the same when I first wired up my X8. Now I have the power cables and the servo cables about 6" apart, no noise whatsoever without changing any hardware.

    Sounds like EMI. Have you tried to shield your receiver from the servo cables or installed graphite rings on the servo cables?

    I get some twitching when my 433 transmitter is too close to the servo or servo line. It's fine if I turn off the radio or move it further away.
