Never mind what I said about planning to hang the wings this weekend – I changed my mind. It occurred to me that the main reason I was planning to fit the wings to the fuselage was to locate the points where the fuel plumbing and electrical wiring go through the fuselage sidewalls, and also because that's the next step in the instructions. But, there's really no need to do it now: the fuel plumbing passthroughs are marked with prepunched holes, and I can just measure where the electrical conduit needs to go. Just to be sure, I called Van's and they confirmed that I can wait to do this until the airplane is nearly complete and in the hangar. This is great news, because I wasn't really looking forward to having one of the wings sticking out into the driveway.
