**  I wasn't satisfied with the gap between the ailerons and the wing when they were in the up position so I decided to spend some time and close them up. To do this I created a carbon fiber board, 2 plies thick. I just laid them up on a sheet of plastic on the workbench. After saturating the cloth plies with epoxy, I overlaid them with perforated plastic, peel-ply, felt absorbent, another sheet of plastic, and pressed it all with a weighted wood board. After curing it all peels apart and the board is very strong but light weight. I sanded the boards edge against a steel straightedge.

  I applied multiple layers of tape to the ailerons, with the last being duct tape, (since epoxy doesn't stick to it). You want some clearance for paint. I recessed the area on the wing where the carbon strip was to go. The strips are only about 1 1/2" wide so a barrel sander in the die-grinder did nicely. After all was fitting well the strips were epoxied in place. After that it is only a matter of filling and sanding, filling and sanding, etc. I use Krylon sandable primer, let it cure well and then sand with 220, 400, 600, 1500, and finally 2000 grit wet/dry paper. It comes out nice and hard, smooth, and should be compatible with most finish paints.

**  I also went around and found places that needed some filling and sanding and a better finish. The trailing edge of the rudder was one of those places.

**  Now all I need is my engine. Any day now!
