The alignment is easy. The aileron is mounted so a jig to hold it is useful. You'll need it later anyway. Search for wingtip mounting methods. Lots of ways to lock the aileron in trail. I fabricated a jig. Long piece of flat aluminum drilled to match the tooling holes with a line from end to end. Bolt it. Line up the aileron to the line and clamp. Trace the surface to the jig. Remove and trim exactly. Grab a piece of 2x4x12. Trace the cut out and cut. Bolt the jig back in place. Slip the block over both the jig and aileron. Locks it in place in trail.
Clamp the flap with hinge per the tips in the link above. Grab a long piece of aluminum angle. Lay it on the edge. Move the flap till the angle is in contact with the aileron and flap. Double check the gap.
