Final sand the edge of the plastic. Very important to get a nice smooth edge and to round the edges slightly. Followed directions for the assembly including the tape medthod of holding the lens. It all worked just like they said it would. Several times I started to jump ahead because I knew what to do next but the directions had other plans. Only later did I find that had I gone ahead I would have made a mess of it all. The directions overall were very good.
NOW I am ready to install the leading edge onto the main spar. Colecoed it all together, looks good!!
