OK I noticed that in flight, especially at higher head speeds, my HBK2 would kinda twitch every now and then, I set the heli down and slowly moved the cyclic and noticed that my front servo would kinda of stutter and twitch at near center stick if I just barely moved the stick the servo would shake, I replaced the servo and it still does it. I am using the stock transmitter and servos. Any ideas as to what could be causing it? I have some of my own thoughts but I would like to have them confirmed by more experienced pilots before i go and do anything serious.

Mine did that and I put a ferrite ring on the wire from the ESC and it stopped it. Now I have a ferrite ring on everything.

Get this! I took the transmitter apart and wiped down all the electronics with wd-40 because I read in one of these threads somewhere, (A belt cp thread) that it cleaned up the signal from the TX, and.....IT WORKED! no more stutter on the servo. I allready have a ferrite ring cactus, so I figured that couldn't be it. but I can't imagine if i didn't have one.

Could you be a little more specific as to what you wiped down, maybe I need to do that.

I have one of the WD-40 pens, I just used it and went over the backs of all the PCB's and i wiped down every electrical connection inside the transmitter. and I put a drop inside all four pots. I'll post pictures as soon as i get my camera back from the inlaws.

I have some spray electrical contact cleaner, I'll Just take the back off and hose it down and then blow it out with my compressor.

Sounds good
