Today I got back to building. I'd taken a couple days to move to a different hangar last week. Then I left town for a few days for the weekend. First I fit and drilled the trim lever, flap detent assembly. Then I worked on the battery box. I thought the design was a little flimsy for a 13 lb battery .. so I added an angle on the bottom. I'll also add some kind of reinforcement on the interior side of the firewall .. probably a piece of angle or a doubler.
