Cheers Greg, tenacious as ever!
It looks like Most of those !:400 scale models are made by Mirage Hobby. I would like to avoid them if possible as it is Mirage that make the Sub I have and I am not too impressed with the assembly of it. There are no locating pips to aid alignment. If the larger kits are anything like this then it would be a nightmare assembling.
Has anyone built any Mirage hobby kits?
