Here are some pictures showing the ailerons being cut free and the servo being reinstalled:

With a little luck the first flights will be next week in Phoenix.

A cutoff disk was used to gently cut through the inside layer of fiberglass cloth between the foam core and wood.

This evening the model was wet sanded (800 or 2000 grit sandpaper) to remove any grit present in the finish. I followed by polishing and waxing.

In just a few minutes the paint is dry enough to remove the tape and stencils.

The surface was lightly wet sanded prior to adding the stencils.

I dry sanded the surface of the primer with 220 and 400 grit sand paper.

There were a few areas that needed touch up. I will fill, prime, and sand those areas again.

I followed by filling any larger holes with polyester filler (Bondo).

In about 30 minutes the filler is dry enough to sand. Lightly sand as required.
