This was a catastrophe. I had just finish sanded this wing and it was ready for the finish. I put a couple nails in a piece of masonite to hang the wing from the servo hatches. I leaned the masonite against my heavy engine test stand at the end of the driveway and went inside to get my cameras.

When I came out, the board had blown over on it. You can imagine how heavy this board must be - again, it's 1/4" masonite. The wing absorbed the full impact. Needless to say, I wasn't feeling well when I lifted the board to see the damage. The entire top sheeting had hundreds of pieces of driveway gravel embedded in it. Some of it punched all the way through the sheeting.

Making it worse, this plane is getting a natural finish, so I can't fill with putty like I would any other plane that is getting painted.

Anyway, some water and a hot iron took care of most of it, but it was still a sickening experience.
