RE: Lightning Build
The nest step it to trim the turtle deck sheeting and glue into place. Since the fuselage curves as it goes back, the edge of the sheeting is not straight. To mark the shape, I tape down one side, and then trace from the inside. Once I cut that, I tape down that side, and then mark the other side. One trick is to leave excess sheeting on the forward end so if you trim too much, you can just slide the sheeting back and it will still fit.
I glue the sheeting on with Gorilla Glue. To prevent a mess, I mask under the seam with electrical tape. I tried blue painter's tape previously, but it adheres to the glue and makes a mess. I used long, heavy balsa sticks running down the sides of the sheeting to ensure it did not bow as I taped it down.
