Finish drilling the holes for the vertical stabilizer. This proved quite taxing, once clamped and lifted to right height it was a matter a using the right angle drill attachment and back drilling through the tie down bracket. I measured and remeasured each hole with my digital angle (91.5 degrees each side) after each hole was drilled and bolted. Love that drill attachment, it's a must have for builder's. Using the digital right angle measuring tool (bought on ebay for $44.00 Aus) It's gotta be square. Temporarily mounted the entire empennage, the only thing I did wrong was have the rudder stops upside down, so drilled out and fixed that hiccup. Wow it is a big tail end, looks good.
