i remade the entire ship :3. i hope you don't mind. i got rid of the piston engine, and the TNT cannons and replaced them with 5 fire charge launchers (their the new hype, in spaceships of course). i also added some engines using the redstone lamps, and added in a "warp core thing a ma-jig" there are three levers, if you pull the middle one it will shut down all the lights inside the ship. added some crew barracks, also added captains room with a survival Kit in case the ship was to be abandoned. added a sickbay and a transporter room (does not actually transport XD) also added a science lab and a cargo bay. ive been trying to make it so that if you shut down the core, you shut down the engines too, but still haven't figured it out yet. if you want me to i can send you the save of the ship. was also thinking about making the ship bigger, not in length, but in size. with your permission i would like to post a download on my page. il give you credit of course ( if it wasn't for your model i would have never gotten the idea to build it) if you don't wanna just tell me k? k :D
