something funny about the UC leg alignment, they look at different angles, and too far angled back. They are also back to front, so the links face forward..... IIRC the Tamiya legs (looks like the Tamiya kit?)are angled at the top...so if fitted the wrong way round that would cause the angle problem.
Yeah it is the tamiya. I thought something looked funny now that you pointed it out it very obvious! I shall try and flip round the right way and see how it goes!
So the legs are well and truly glued in place I think it's going to have to be one of those things I learn from!
