March of the lead and jigs. The trailing edge is pinned, lower spar is propped up on scrap 1/4" pieces with "T" pins beside it to align it and then the little plastic jigs are used to align the ribs. The 1lb lead ingots hold the upped spar down, 1/2 lb ingots to hold the rear of the ribs to the trailing edge, and I just work my way down the panel with CA. I like to build with Titebond II, but I will endure the CA fumes and assorted risks for hos easy it makes framing up wings.

I did trim two ribs to accomidate the sheeting I will add in the bay that will sport the aileron servo. Haven't decided on just how that will be mounted, but that can all be added later.
