I noticed that the original speed brake was cut out well, but a little rough around the edges so I decided it was a good project for Z-grip practice :) I layed out the duct tape, closed the brake and mixed a batch. I'm really surprized how easy this stuff is to work with compared to dry micro. what a blessing. Being that this job required tedious trimming with a razor blade it took a few hours. After sanding I added another batch to the belly area behind the brake as well. My objective is to do as much as possible underneath the airplane before installing the Spar which is when it becomes a little harder to move this thing around. :)
