For the last week I've had a miserable cold, so am not hitting on all cylinders. Yesterday and today I didn't reallly get a lot done, but did make progress. I've reinforced the aileron trim servo fairing with 2 bid, and the result looks pretty good. Tonight I sanded the fairing reinforcement and cut out the opening in the lower wing skin to allow the aileron actuating rod to exit from the bellcrank to the aileron.
