Thanks for the feedback.

A bit more progress has been made. I spent quite a while sorting out the landing gear and ended up with something a bit more complicated than I had intended, but happy with how it has turned out.
The orange bits are cut down covers from inkjet cartridges:

Everything else is plastic card/tubing and brass rod for strength:

Each foot has 3 'jointed' supports, but its hard to show it clearly from a single angle. The brass rod will fit into mounting points drilled in the bottom of the hull.
Hopefully I can crack on with the rest of the build now. I didn't want to complete the main body until I knew if the landing gear would work and how it would fit into the underside. I have a pretty good idea of how the rest of the model will come together. Up until now I have been rather making it up as I went along, which makes for an imperfect design. I have however rather enjoyed working with plastic card on a larger build.
