Darticus,
I'm far from an expert at this, but I had to go through my Belt CP after a collision with the ceiling. I started from scratch and as I went I got my work verified. But I missed something, so maybe there's something here that will help.

Tracking is viewed from the edge of the rotor disk. It's like looking at the EDGE of a round pizza stone. You want safety glasses on, and you are looking at the blade tip as it comes at your face (from a safe distance).

At half throttle you should be at zero pitch. You can check that with the motors disconnected (pull any two motor wires). Put the throttle at mid point and trim BOTH blades for zero pitch.

Mark the leading edge of one blade with tape or something that will be visible at high rpm. White Out works fine
Either mark both blades with different colors or just mark one blade.
Mark the leading edge of the blade(s) near the tip.
I place a bright light behind me so it shines over my shoulder to illuminate the mark on the blade.
Now look at that blade edge as you bring up the rpm.
Both blades should look like a single knife edge.

If you see two tracks, the blades are out of track. That means that one blade has more pitch than the other AT THAT RPM. The marker you put on one blade should be visible and that allows you to see which blade is higher.
As you look at the blades they should be straight out. If one is low, it needs more pitch. If one is high, it needs less pitch. Again, with zero pitch, both blades should be dead flat level.

Here's the part I messed up. When I replaced the feathering shaft I over tightened it. The flybar must be free to move - free to pivot easily. Maybe if you have a LHS, you could ask them for a tip on how tight is correct. Anyhow, I overtightened my shaft and every time I adjusted the blade pitch and checked tracking it was different. And my cyclic control was pretty slow. That was caused by the feathering shaft being too tight.

Was anything in there worth the trouble? I hope so. If I can help someone on a CP machine, I'm getting better.
