What is with the bearing located in the centre of the main rotor housing? Is it a bearing for a see-saw for the feathering shaft? What improvement does that feature offer?

It seems to support a center pivot for the feathering shaft.

oops, bounced it!

It keeps the motion of the "floating" axle limited to flapping and no lead-lag.

The jury is out on what "feels" better. I normally remove the center pivot from previous Hirobo and TT heads because it improved the smoothness and some interactions of the head and outside elements, gusts, etc.

Even though these were flybar applications, I am finding out I also prefer the feel of a purely floaing axle in FBL to one restricted.

From purely machanical standpoint the FBL systems should like it better since they have no momentary variance in head timing, but the top FBL systems handle all those very well already.

Try the head the way it comes, before you go experimenting...

I don't actually have an x7, just curious about the new head design and how it feels. Can you run the head without the seesaw?
