It's sad that so many folks don't recognize that such engineering models are actually beta testing for the Thai Moon Mission.
This piece, for instance is a radiation barrier for the spacecraft Bay windows. I guess you all believe the Chinese submarine purchases are intended for marine use? Silly rabbits!
And those Chinese engine purchases? Just a distraction. The real spacecraft will be powered by 4,298 motorcycle engines operating in tandem.
This is just a way to hide the massive 'black project' costs of the program from the public.
So, for all you cynics:
"put that in your pipe and smoke it". And....... that's legal now!
