Well, BAH.

Despite my better judgment, I decided the 1/4" TE stock on wings/stabs would be "enough" for the hinges. That proved fatal.

Plane lifted off, flew like an absolute DREAM...really was looking forward to getting to know her. Then the right aileron parted company with the airplane, at a "kinda low" altitude. Chopped throttle out of instinct, plane slowed quicker than I expected, and rolled ever so gently off to the right, on to her back, and I simply didn't have the time to get her back.

Ah well...all the expensive stuff survived, and I MIGHT do the work to fix her up...have to take an extended look at her today or tomorrow to see.
