Tail drift with V-bar

[Eyefly]

Here is a real question for the local V-bar gurus:

I am getting more brave with the v-bar and decided to flip the bird over yesterday. In right side up hover, it is solid and there is no drift on the tail. When I flip the heli over and hover inverted, the heli rotates slowly counter-clockwise. I cant for the life of me figure out why this is. Any one here have any insight as to why this is happening?

I looked at the settings and there is a "Symmetry" adjustment. Anyone know what this adjustment does?

It could be the gyro wires to the mixer, it's so long that it picks up noise easily. Try to wrap it by itself and isolate it from the other servo wires.

I have the wire isolated. Perhaps it is my setup which is incorrect. Am I supposed to have the blades at zero pitch at mid stick?

It doesn't matter as long as you have near equal travel. Is your Noise Elimination box checked as digital noise can cause tail drift - might also be worth putting a metal plate under the gyro unit
