Scott, I assume you meant to say "I have(n't had) this problem since using......" unless things have changed since your previous discussion of the topic.

Chris,
 
Problems? That depends on the meaning of "problems."  The oversized hinges are terrific in that there is no looseness of or extra resistance in the control surfaces or flaps. On the other hand, I am experiencing "wear" on the outboard elevator hinges (especially the left) as evidenced by aluminum streaking trailing behind those hinges after several hours of cruise flight. 
 
Dirty air from the prop?  A harmonic from frame vibration?  And, for a really technical description, excitation from an overly wiggly tail?  I am just wondering if other small-tailed LNC2's have seen this situation.
