Here are the main support pylons and the tram tubes that go between the landing bay sponsons.
In order to mount four landing bay sponsons, I had to redesign the support pylons to make a "Y" shape.
Here are the parts for one. I laminated the "Y" part to (roughly) 2 mm thick (so that the skins have a good surface to attach to).
The "Y" support pylon is assembled.
I assembled six "Y" support pylons.
Here are the parts for the tram tube and mounting.
The tram tube and mounting are asembled.
Since there are four landing bay sponsons, I had to attach two tram tubes and mountings.
I attached only four of the main "Y" support pylons. The tram tube is replacing the center "Y" support Pylon.
As you may see, I had to cut the tips that protruded off the ends of the "Y", so that the sponsons will sit properly.
