What would cause tracking to go off?

[Edwinssiv]

I searched and did not find what I was looking for...
What will cause the tracking to go off. I had the tracking right on...I took my heli out and started flying. It was flying great...very smooth. I went into idle up and still everything was good. I did a back flip, I heard the blades go out of track but it came right back and was smooth again. So I continued to fly more and then did a front flip. The blades went out of track again, bad this time. They did not recover again.
I have gone over the entire head, everything is tight. I checked the blade balance and it is very good. I checked the flybar and it is straight. I have checked the balance of the flybar and paddles and it is fine. The main shaft is straight. the spindle shaft was just replaced and is straight. I pulled the dampeners and they look good. There is no movment in the blade grips in regards to the dampeners. Could the dampeners cause this?
I have the HDX 450-HSS all metal head and it has about 15 flights on it. Blades are Heli Directs Carbon Fiber 325mm CF-450MB

Any ideas?

Could be a bunch of things..
The first things that come to MY mind is:

1. lose links
2. head slop
3. blade flex
4. bent shaft
5. bent spindle
6. One blade tighter than the other


I am sure there are more but those are the only one's that pop into my head right now..

edwin, did you solve the problem ?
I have the same problem over here. The tracking changes after doing some loops.

My tracking is off at the moment and I know most of it is due to the bearings in one blade grip have more slot than the other. Changed the ones in the sloppy side and the new ones have the same amount of slop. Just havent gotten around to do the tight side yet.

I took the whole head apart and re-assembled it, re-locktite it and that fixed it. I never found what exactly was causing the problem though.
