Hover Tank update

Hi everyone, as a change of pace from the fighter conversation, I'd like
someone to take a peek at the update to the hover tank that I posted
about
back in March.

Let me know if you think it works or not.  I've added quite a few
details,
and some moving parts like hatches and thruster exhausts.  If you can
think of any details that I might be missing, let me know.  Last time
everyone gave me lots of very helpful constructive, and it helped me
develop the design a bit.

Thanks,

Randy Wolfmeyer
