Thank you, you've done a very good job with your project, do you have any more recent photos? what you have done is much more than I could do as my DIY skills are not that good, i have this condition called Dyspraxia (nowadays its called developmental coordination disorder) it means I am not that good at performing certain tasks, especially if it involves using tools doing up buttons and shoelaces is hard enough for me! I did put together the base that my main panels sit on, that is the first and only thing I have constructed myself and I was pretty pleased with it, still, I have come this far so i can't give up now I will just have to do as best as I can but it certainly won't be anything like yours. You even went as far as to use primer, I'm guessing most of that structure won't be seen once it is complete but for realism you did it anyway, that's very impressive.
You are right they do take up a lot of room, especially when I am living in just a 2 bedroom flat (apartment) I am having to pay extra on my rent for that bedroom as in the UK you are renting and have more than one bedroom if you are living on your own you have to pay extra, but it makes me happy so I think it is worth it!
I also live on the top floor, luckily there are only 3 floors but there is no lift so carrying some of the heavier parts like the windscreen up those stairs was a nightmare!
