Twitching servos on blade 400 problem

[Dilbeck]

After 2 slight crashes from a steady hover to a jumpy (all of a sudden) crazy heli, took her inside and noticed as i moved the sticks around the servos were twitching a little now and then, it was like a delayed input or somrthing. Went to the d/R and expo menu, mine were set a 80% on D/R and 20% on expo, nothing on rudder. Moved the D/R back to 100% and the twitching stoped, Moved D/R to 90% still ok, but at 80% the twitching came back. Is this a radio or servo problem? If your in the air and this happens you better be high enough to recover because it happens at the blink of an eye. Have a call into tech support for an answer for the problem..

Think i found the problem, Talked to the tech support guy chris and he thinks a servo has a short and is causing this, I narrowed it down to the tail servo, going to the rudder on d/r and expo menu in the expo setting set to INH and all problems went away. Set it to from 9 and above and the twitching comes back to all servos.
