Let me say that I never believed from the word go that blades that are balanced perfectly with no warp could possibly not be adjusted to track. Today the little brown truck brought me a new set of blades, grips, bearings, etc..

To be sure you guys were satisfied, I balanced and installed the new (identical) blades, without making any other changes. I took it outside and they didn't track. I made two adjustments with the double link on the marked blade, (up one turn, worse, down two turns), PERFECT!

Heliproz is buying the back. They have always treated me well. They said if they weren't warped, they must have a weight moving a little in the foam inside the blade.

Thanks to all you guys, (who apparently crash a lot more than I do), for the benefit of you experience.

Seriously, I really appreciate your help.
