The ailerons hinges are moulded into the skin of the wing, although this sounds complicated it's actually very easy to do. As simple as laying a piece of 4 oz cloth that is cut on the bias (threads at 45 degrees) on the core across where the hinge line will go.
The ailerons are marked out on the finished wing, the ends are cut with a saw and the bottom skin is cut with an exacto knife using a straight edge. A cut is made parrellel to the hinge line to give the ailerons just enough clearance to deflect downwards and the foam core is picked out between the two cuts. then using a steel rule as a guide the hinge is creased, very easy to do and they work perfectly !!
Here's a pic
Here's the bottom showing the gap cut in the bottom skin and core
