Removed the left skin from the micro release layup, then began working on the rudder trim access panel and laying out the rudder trim tab. I misread the manual, and removed core material from the right skin where the trim tab is, rather than the left side as directed. This should not be a problem, though. I'll just reinforce the right skin with a layup. The only real difference should be the difference in weight, but that will be negligible.
