Digital servos always "buzz" they also tend to like the higher voltage, 6V. You will also find that some servos are affected by RFI from the VTx. HiTech are pretty immune from this noise and are a good "safe bet" choice. Search the forum for susceptibility to RF noise and you should find some studies.
Thanks for the recommendation, Steven. I've disconnected all RF sources (and minimised my Radio TX output) and still I get jitter. Interesting site btw!
