Bit of a long term project this one, I've had it going a while as shown in my Akira thread and I suspect it'll go on for quite some time, but here's where I am so far. I've spent a long of time gently tweaking the form and to my eye the secondary hull is now pretty close but I'll keep playing with it. I'm using the 6ft model exclusively as in my opinion its the much better looking model, I'm not going to tweak the saucer to account for ten forward either.
Next up I'll probably sort the junction between the secondary hull and the saucer as that's very rough at the moment. Then move on to sorting the nacelles out.
