Now we need to mark and cut out the control surfaces.

The best way to do this, starting with the wing, is to make a poster board template. If you just free hand it, you're less likely to get it equal.

Mark out the cut lines, the relief lines for all of the capping, and the servo boxes.

It's critical to extend the wing capping into the wing about 2 1/4" or so.

Make all of your marks on the bottom and leave the cores in the top shuck for cutting.

The best tool for this job is a band saw. You can cut it out by hand if you mark both sides and trim/sand to the lines, but a band saw makes this job painless.

Make certain your band saw table is 90 degrees to the cutting blade. begin your cut carefully and cut about 1/8" away from the actual outline. This will allow you to sand to final position for a perfect fit.

Cut out the ailerons, and then trim away the excess material.
