I've decided to go the 'break the bugger' route. I've sawn off and re-positioned.
I'm figuring that the newly glued 'connect' will be sufficient for these models - I've just rotated the B wings through 30 or so degrees, doing more would entail other, beyond me, modifications to the model to make it look true.
It's funny, but of all the models, I think the B Wing looks so 'wrong angle' compared to all of the others. Is that just me?
Was it just a 'space occupied' issue?
The other model that I wonder about is Slave 1. Surely a model angled at 45 degrees? But, this one is a difficult one to change (will not bother).
