Finishing off the ailerons

Absolutely cruising!
Second aileron is a copy of the first.  On Friday evening, I grabbed the second aileron leading and trailing edges from the garage and headed to the basement.  To match the hinge angles, I bolt together the leading edges and lay both control surfaces (the old and new) on a flat table.  This way, the first angle sets the second, and can be transferred to another surface as needed.

This picture shows a whole row of ribs on the first side being bonded in, and the stiffening carbon rods are installed too.  On the left is the first aileron that I'm using to copy the hinge angle.

 After waiting overnight, here are the tips ready for more.  First step was to add the trailing edge doubler (or whatever I called it last time) out in the cold garage.  Then, I took some scrap ribs and modified them to be shorter and cut with an angle to match the trailing edge.  They were also thinned a bit toward the trailing edge to make a nice transition.

After bonding in the tip ribs and respective carbon rod stiffeners, here's the pair of ailerons curing in the basement.  It'll be a few days before I can assemble everything again, with some travel early this week and rainy weather late in the week.  The next assembly day will look at the flap linkages and the aileron control linkages.  Ah, I also have to epoxy on the control line guides in the wing before then.  Always something to do.  Fun hobby :-)
