There are actually 3 different output shaft that were used for a while on the JR 8611A.

The H9 arms can have a mismatch and strip itself if U have one of the smaller output arms.

The Latest Arms I am hearing are much better QC. My F15e almost lost the Stab because of this problem. There is info here on RCU about this very problem the owner of SWB advised me of it a few years back.
