It took 4 hours to get the wings in place, they are a very very tight fit, the right wing went in easy but the left one was moving millimetres at a time. Anyway, they're on and they're not coming off. In the end I decided to use the AN6 bolts after all, I was going to use the trailer hitch pins Sonex uses on their aircraft (I bought them from McMaster) but changed my mind, the bolts give me a warm fuzzy feeling.
