Drill and cleco. We used a lot of our 40 copper clecoes. This must be what building an RV is like. 🙂
Strap the wingtip on, install the aileron and check the spacing. It needs 1/8″ clearance between the wingtip and aileron. We’ve got a 1/8″ thick piece of plastic sheet taped in the gap.
Here’s a pic I saw of a Searey where the pilot hit the wingtip on a dock pole. It probably bent the spars because it twisted the mounting pylon.
