Trex 600 Flybar See-Saw Arm Issue

I took the Trex 600 Flybar up today. It seemed odd that I could not get the tracking of the main blades to hold in flight, they went way off one another, but at zero pitch they matched. During the flight I suddenly developed very wishy-washy control and auto'd her to a lamding.

On inspection of the head she had thrown the see-saw screw and flange bearing... This was the same thing that happened before and I thought repaired. I took the entire flybar cage apart and found that theatttachment for see-saw screw that secures the flange bearing is stripped. It barely holds the screw. It seems snug, but a gentle tug pulls it. I need to replace the see-saw.

Parts for the flybarred Trex 600 main rotor system are getting very hard to find. You can't find a replacment head. Even HeliDirect is NIS for many of the parts, but I did find a new see-saw, but got the last of their replacment flange bearings. I am about to start the build on my Trex 600 EFL, so really dont want to conver this one to flybarless. I really like the old school flybarred heli.
