I just got a traxxas 2.4 tx/rx, and most of the servo's i own(10 or 12) twitch when connected to it.
they dont twitch with other rx's I own, ive tried a few and work fine.

most of the servos im using are digital.
brand new batteries in the tx
already reset the tx/rx back to factory settings.
the tx/rx are new, so they dont have water damage.
the antenna has not been cut.
we deal with very sensitive x-ray telescopes at my job, we have a room which is built specifically to block out any radio interference, and it still twitches in there.

I can get the twitch to stop if I turn the wheel rapidly to one side hold it, then release slowly back to zero.
Once the twitching has stopped, i can turn the wheels slowly back and forth, without issue, but as soon as i turn it a little faster it will tweek out again.

any opinions?
