This thread has got the old grey matter wakened up. Now, this is just some thoughts on the stability issue - would it be possible to incorporate, say, a pair of I-beams into the hull bottom, into which would slide an appropriately weighted section of lead. By this I mean the top of the I-beams would be on the inside of the hull and the remainder external. Then, when it comes to displaying the model, an appropriately shaped "plinth" could be slid into the I-beams in place of the lead, thereby mounting the hull proud of the display stand.
Having said all that, I've never tried the idea myself. Could be a way to go but of course would add some more time into your build.
As I say - it's just a thought....
Looking forward to the build as well by the way.
Regards,
Ray.
