Luke is about 12", Han is about 12.75", Fett is 13", Vader is 14" and Chewie is 15".
How well do they fit in with old Hasbro 12" or Sideshow figures? What did you think of the electronics?
The stormtrooper is the best of the 4 currently available by far. I personally think they are better than the old Kenner/Hasbro figures. They've got nothing on Sideshow but I would use that as a metric.The electronics as far as sound goes is awesome. The voices all sound authentic as do the blaster fire shots and saber effects. I can't wait to see a painted/finished sample of the Fett. There was so much detail in the sculpt I hope they do it justice.
One more thing... Vader's cape & tabards are not hard plastic... they are a thick vinyl/rubber that has some weight to it while still being pliable. Almost like wet suit material - floppy, yet holds its form.
