In fact, I removed some of the extra metal because I felt it was too hard to hold the nose down with zero flaps and full trim. I angled the metal down over the trailing edge of the trim tab to reduce its effect on nose down trim. It's actually angled enough that it adds little if any nose down trim.

My additional area is not greater than the area on the full length trim tab that Zenith now supplies and has tested.

I'm learning about all sorts of new things: transfer punches, reamers, solid rivets. The plans state that the main spar attach bolt holes in the center spar should be drilled undersized then reamed to the proper diameter (5/16). To me that appears to be a pretty open ended statement. If you google "reamer" you get many and varied hits for all different kinds of reamers. Does anyone have a suggestion as to what kind of reamer we should use and where to get one? Should we also ream the bolt holes for 6-ZU-2-4? What have other people done?
