Just a quick update to prove that this project has not been forgotten. It's just hard finding time for hobby at the moment. Anyway, you can't see it in the pictures because the flash washes out all the white detail, but I have added the first armour layer to the whole hull. I have also added the wheel suspension and begun construction of the generator/engine.
I bought a pot of the new liquid greenstuff today, so I shall be having a go at gap filling soon.
