Low FBL Head Setup

[jfluegel]

I am building the low FBL head set up for a stretch 500 and wondering what parts I need. I currently have the Swash MSH51020, Grip set MSH51039, Low FBL hub kit MSH51335 is this everything I need to complete the head or do I also need the FBL uprgrade kit MSH51115? Also, what is the FBL lower plate for MSH51339?

Thanks for any help you can shed on this. All the various head options for these birds is confusing.

If you do not have the FBL kit you need MSH51118 FBL long balls, MSH51119 FBL Spindle, MSH51120 FBL swash balls to finish the FBL head.

The lower plate is for the carbon frame to mount the FBL electronics 90 degrees to main shaft.
