Now we're to the beams. Butch saw my pics earlier, and thought the blades are fixed....this is how they move.
The pitch change rod is attached to the pitch change horn, which is attached to the (blade) attach beam and pivots the entire beam, and thus the blade. The first pic is the entire beam, mounted on the "star flex." The star flex actually does flex. When the blades are on, the star flex actually bows downward. But with no weight on the head, it springs upward.
On the inboard side of the beam is the "spherical thrust bearing," which is basically a rubber mount, mounting the beam to the star flex. The same way you can twist rubber, you can twist these. You can't by hand, but back to the servos, and the "power steering," you can. This is the second pic.
The third pic is the "frequency adaptor," which houses the "self-aligning bearing." This is the outboard mount, and is just a pivot point, thus the bearing.
The beam tilts, the whole blade tilts, the helo flies like you want it to.
