I had to start from scratch, today all over again , as far as the aft engine car goes. It seems that after I was done mocking up the model with all the cars in place, that something did not look right. Here, compared to the wing cars, the aft car was too small, so I had to totally make a new one for the model. The aft car on the R-34 is the same height and width as the wing cars, but since it has TWO engines front to back in it, driving one 17 foot diameter propeller, the car is about 25 percent longer than the single engine wing cars. So I made a new one in the appropriate bigger size. NOW the model looks balanced, and asthetically correct. All the cars were then refitted, and the model was checked for overall alignment and proportion correctness of the cars, keeping on tweeking until I felt happy with how the model airship looks to me. The cars are now ready to have the woodgrain in them sealed, to get them ready to spray paint silver, and then top dull clear coat them before the window and door details are applied. Then and only then can they be attached to the hull permanently. I guess I should actually fabricate the four propellers, paint them and attach them to the cars before I glue the cars to the hull beforehand. That is where I'm at right now. Here are pictures of the model with the corrected aft car in place and all dryfitting of all the cars to the hull completed.
