Started on the stinger. Trimmed the two lower halfs and taped to the outside of the skin to get an idea of how to trim, then trimmed the leadind edge to fit the bulkhead but leaving the stinger much longer than needed. Did the same to the top. Taped the three pieces together and trimmed to fit the bulkhead but still about 2.5 inches to long. Trimmed each piece 1/2 an inch at a time following the countour I already had. Kept trimming until stinger was about 19 inches long then removed. Installed stabilator. Installed stinger and trimmed to fit. I still have a little trimming to do before it's finished.
