Hi all,
I've just finished upgrading my Belt with DX6i, GY401 gyro and a 9257 digital servo for tail.
Problem is when I spin it up, the tail is very twitchy. I can see the digital servo keep twitching and move back and forth. This reduces if I move the rudder to left or right, if I just leave it there tail twitches again.
This happens both if gyro is on normal (sensitivity 60%) or HH mode (80%). The DS (digital servo) switch on gyro is switch on.
I have also tried disconnecting the servo, and the tail doesn't vibrate that badly when spinning up at all, so I dont think it is due to frame vibration.
Please have a look at this video here and give me some pointers in what to do if you can. Any advice would be very much appreciated.

(Note: in the video, at 00:09 and 00:15 the tail is still as I move the rudder stick to left or right, at other times it twitches as rudder is at central)
