No, the 9411 is a dual ball bearing servo, so it doesn't have that play in the output gear that the 811 has.
Okay, so to revisit this question...... If the DS9411 does not have this problem then I would assume the DS8611 and the DS8411 also should not have this problem. I have all three in a new plane (8411 on ailerons, 9411 on elevators, and 8611 on the rudder) and they all chatter like crazy. Is this just the characteristic of digital servos? It drives me nuts! It's so bad it is nerve racking. While the plane is just sitting there not doing anything getting it ready to start and fly, I get nervous just listening to all the noise and twitching. Is there some way to isolate this? When I turn off the transmitter, instant silence.
