The only moving part is the phaser gun under the saucer section which is mounted on a movable turret.
Kre-O (Hasbro) has the Star Trek franchise rights so this will have to do.. The Kre-O Enterprise set is much bigger and has 432 pieces ( Kre-O also has a mini enterprise model too). The larger set lights up ( each nacelle tube has two ?AAA? batteries) and fires a flick missile from above the deflector dish.
