I already sent mine off to Tracy for repair. But even if there is end play in that shaft (which there is a little) it would not affect the flex plate. The thrust bearings in the drive prevent the shaft from moving toward the engine -- and even if it did move that way, it would be stopped by the e-shaft. Forward (in the aircraft) movement of the input shaft (as would occur when the prop is pushing the engine) is softened by a nylon bearing (Tracy has a name for it). The movement is small(like .005), and has no ability to affect the flex plate.

David,
Is it possible for you to measure the wear mark on the RD1-X drive input shaft splines to see if there is any indication that the RD1-X adapter plate has moved in a forward/back linear fashion? If there is, then wherever that is coming from is the problem. It is either flex in the flex plate, or end play in the input shaft.
Everybody is trying to fix flex in the flexplate, but I don’t think we have definitely ruled out end play in the input shaft yet.
