Question about gyro activity

[EatMorePizza]

I just installed the JR8900g gyro with servo combo in my raptor 30, and while hovering with no input to the rudder the tail would swing then stop. What can this be?

I'm using the Dx7 I would pretty much exclude interference from the equation.

Also I noticed something weird, when I switched the power to on I noticed the tail servo (after it has initialized) would creep very slowly to the opposite side. This is during power up and the remote is on headlock mode. I switched the power to the receiver off than on again and it stopped. I'm a little nervous about that.

If its like every other JR gyro turn the gain up all the way in heading hold mode and use the rudder sub trim to eliminate any drift. Turn the gain back down and fly it.

The tail swing is probably not enough gain.
