I built my own star destroyer, it was about 5 feet long, couldn’t get it out of the garage (too heavy) but was told bluntly it wasn’t coming in the house so had to dismantle it.
Want the Razor Crest for Christmas but not idea where it’s going to go. Building the AT AT at the moment, had about 60% of the parts and managed to source the rest for under £300 which is not bad when RRP is over £700.
