Drilled the right side aux longerons to the skin and motor and landing gear mounts. Be sure to make sure your centerline is showing through the holes per the plans. When well, but used 2 #30 bits (dulled). I also have to be careful as some of the holes are #40 and some are #30.
The aux longeron is just above the lower longeron in this photo
Drilling the hole with 'the cup' is great for keeping the drill square to the work - invaluable.
