Been a bit busy doing another project, but all of a sudden, I have a date for a game when I would like to use this...but I don't think it is possible to finish and paint it in time.
To make this thing "fly", I thought I would try having removable tripod legs. Just drilling holes for the transparent rod means the end inside the ship can wobble around. So I thought the answer would be to fit a sleeve inside the hull for the main rod. I got some 6mm rod (off eBay) for the tripod "legs" and some 10mm tube with a 6mm internal diameter for the hull sleeves.

I drilled a 10mm hole in the appropriate spot and measured the length of sleeve required.

I reckon there is a chance that the tripod legs will slip out during a game and this could be quite annoying, so I am putting a pin of paperclip in case I decide to fit a small magnet to each of the tripod legs.
