Quoted from Skypilot:
I received what appears to be the final revision today. I am leaving in the morning on the booze bus. We will be making our way to the Silver Ball Country Club and then to Allentown. When I return and get settled I will get to work on installing this.The playfield is cleared and ready to go so it should not be too long.
Those prototypes have the most amazing ability to arrive just as you are leaving on vacation, or family has arrived for Christmas, or you've just started some other big project.
