I don't know were you can get a YT-2400 with the turrets, but I think I know how to modify it...... First, get yourself a nifty little program called Mx/vtED. I think it allows you to edit turret data..... Just copy the turret axes from the Otana. I tried on the TIE Defender... It didn
't work. Good luck

You don't know fear untill it comes in the form of heavy weapons
