Most of the horizontal stab was completed when I bought the kit. The workmanship on the was fine. I found the center hinge to be slightly off and the outer hinge brackets were mounted an inch off from the location called for on the elevator plans. I discovered this after cutting the hinge locations out of the skins on the right stab. After discovering the difference, I moved the elevator outer hinges to the stab locations. The incorrect cutout area in the stab leading edge was filled by riveting in extra skin material.
