Ailerons have been attached and placed in trail using the jig vans provides and a laser/straight edge on the outboard rib. To that, the flaps were hung level and equal in trail to the ailerons. Once they were in trail, the flaps were clamped and the hinge was drilled to capture that position. A gap of approximately a 1/4” was achieved between the flap and aileron. For me, edge distance was no issue on the hinge, either side. This went smoothly using the “fat rivet” procedure. It's basically putting the bottom skin clecoed on and slightly squeezing a rivet in a couple holes where the skin and flap brace meet to hold everything together until you can drill the hinge. Worked nice and smoothly. I also installed the pvc T for the wiring.
