Shhhh - don't tell anyone...I got to take most of the day to pretending to be an airplane assembler! Bottom wing was straight forward repeat of the top wing - test fit, glue, and clamp in place. While it was drying I moved on to the tail feathers. The instructions are clear - especially the measure 3x and cut once. I followed the advice in Ken's Ultimate build thread and used a piece of mason's string to find the mid point of the turtle deck for my measuring device. I found that a hot exacto knife is the bomb for making quick work out of cutting super-clean openings in airplane covering (I can never find the knife with the SHARP blade...). Mark the horizontal stabilizer and remove the covering and glue in place with 30 minute epoxy - Q.E.D.
