i may not have a scientific reason behind my fear but i would say get rid of the "y" for sure. try plugging each servo into an individual channel and see if you still get the jittering. there is a smart-fly EQ6 on rcu for @ $200 right now and that would be a viable option for you if your servos are alright. i just hate "y" setups. i have always had some sort of bad luck with them. please don't think that i am bashing anyone that uses this setup, i just haven't been very successful with it myself....

good luck brother.
