NX-01 is wobbly because of the half-curve stand, but the ship is very light so it copes well. The Ent-E has the best stand design, it's got 2 curves and is pretty stable and balanced, but limits range of motion on the ball joint due to the ball being too low. The 1701-A I haven't used the stand on yet, I will when the WOK 1701 shows up later this month though, but i have a bad feeling about it.However, my 3 Star Trek ships stay on their stands just fine:
Too bad you want scale, Playmates' Defiant is huge and beautiful, easily their best effort to date, and one of their only ships to use ACCURATE sounds.These are all the ships I want unless I find somewhat good scale Defiant and Voyager toys.
I just might go for Klingon, Romulan, Cardassian, Breen, and Jem Hadar ships in the future (maybe Ferengi, Tholian, Vulcan, or Andorian) but I'd want a Borg cube as large as my coffee table. Ha! (Maybe a sphere the size of one of those exercise balls could work though).
