I have been busy the last few days tracking down a problem with my laptop so there has been only a bit of progress.

Well, it seems that the next step was to sand the wing mounting area to be a bit more accurate. My plan was to place the fuse on a flat surface and then place the wing on the fuse and measure the distance from wing tip to floor. I was going to sand the wing mounting area until the wing tips were at an equal distance from the floor. My workshop is too small so I brought the fuse and wing in the house to the basement. I used a square to confirm that the fin/rudder were perfectly vertical. I then placed the wing on the fuse and measure the distance from the wing tip to the floor. I was pleased to see that there was only a one inch difference. I removed the wing and sanded a little and put the wing back on the fuse. I repeated this process a few times but I couldn't seem to get it right. Eventually I realized that with each wing halve extending 54 inches, even the slightest shift of the fuse would cause the distance from tip to floor to change dramatically. I decided to change how to do this. Since the retracts have been returned from Century Jet Models, it seemed logical to mount the retracts and extend them. The wing should be level so then I would need to sand the wing mount until the fin/rudder are vertical.

In the midst of my attempts to sand the wing mount to get the wing level, I realized that the wing wasn't sitting positioned where I expected. The photos and drawings show the top side of the wing protruding just a bit above the fuse and it seemed that I had it just a bit too high. I went back to the CAD files and obtained some measurements that I will need to add to the docs. The reference for these measurements is the rear, bottom, center of the wing mount. Here are the correct measurements: The distance to the point where the trailing edge of the wing halves meet is 1.9" forward and 0.7" up. The distance to the point where the leading edge of the wing halves meet is 17.75" forward and 1.5" up. You can see that the leading edge of the wing is higher than the trailing edge ( elevation of the trailing edge is 0.7" and the leading edge is 1.5" ).

I used these measurements to discover that I did not have the wing in the proper location. I carved the wing mount to get it closer to where it should be as shown in the these photos.
