I was installing multiple Fantom Helix RS Works Editions over the long weekend. Threw them on the Tunalyzer to write down the specs for future reference. I had a titanium timing adjustment screw shear off loosening it. The replacement then broken before snugging. After taking of the end bell I could remove the screws with my finger tips. Did you have issues with the timing adjustment screws breaking?

I also rebuilt my Hobbywing V10 G4s. I noticed single shim you referenced in your comparison videos. I was disappointed with the amount of play in the rotor though. I also changed to titanium screws and ceramic bearings. No change in performance for me.
