Aft-facing torpedoes are firing from the ventral tractor beam emitter instead of the torpedo launchers on the back of the saucer.

The feedback forum would probably be a better place for this, but also, there's a thread bout the shortcomings of the model in the tribble forums if I remember correctly. Might be worth having a look, seeing how many have been fixed, and making a final list of outstanding model issues and posting it int he feedback forum.

Just like the Odyssey fires beams from its nacelles and the klingon carrier fires all guns from the tip of its nose.

Weapon hardpoints -really- need to be re-done so it fires from the parts of the ship the guns are really at.
