I understand the kits are not that hard to build..i have put some parts together & looks like they might need a load of putty but generaly look ok ...the only things i have heard is that technically they can be wrong , missing bumps & lights etc..if you do a web search you can see some reviews of the kits
I was going let you get a bit more done before I commented on it. You're a keen man. The Starlifter is 1/144 scale to fit in with heavy lift theme, to go the Revell AN-124, C-17 + B-2, Trumpeter IL-76 and if I had to do what you're doing it would be staying in the stash for a very long time.
I am very excited to see what it's like in the box.
