I finished up the z-angles this morning and knocked out the top cover while I was at it. While I've got the big sheet of .025 out on the table, I'll page through and make the parts that spec .025. There are a few, but in general it looks like the fuselage uses a lot of thicker stuff (.032 & .040.) Since the cutout in the rear top cover was an odd size (60mm), I used the flycutter to cut the holes, then used the Olfa knife to trim out the rest. Once I had the Olfa lines scored fairly deep, I used a pair of snips to cut a line down the middle of the piece I was removing so I could just snap the side pieces right out with my fingers.
