I do not plan for the back deck to be down.
Academy’s is still a better option with more exterior details as well. The interior is really where the Academy one shines though as it is much better detailed. Academy’s does have an A2 two-piece rear engine bulkhead (in front of TC) though, as opposed to the one-piece in an A1.
I’ve not built the Academy one, but I used the Tamiya kit as a hull for my TUA a while ago.
It’s showing it’s age, but if it’s staying buttoned up and you don’t mind a little scratch work or after market, I think I got mine for $20.
Thank you gentlemen!
