Dimpled horizontal stabiliser and elevator ribs and some skin areas. Upsized hole on one side of rib for VOR antenna. On the other side a Dremel was necessary to grind a recess into the slot area in order to clear the antenna. I am planning to run the VOR antenna cable in front of the vertical stabiliser front spar and have already upsized the holes in ribs 5 and 6 to accommodate that after clearing it with Sling. Drilled two additional 4.8mm holes in the front rib 4 and the antenna base plate for cable tie to secure the antenna cable.

Potential gotcha: upsized the holes in the lower part of the rear spar and doubler parts 8 and 9 to 4.5mm to allow M4 bolts to pass through to the rivnuts behind them (must be done before riveting everything together, the plans don't indicate this: can't drill the holes larger once the rivnuts are installed and the assembly is riveted together). Likewise for the stabiliser skin lower rear corner holes.
