The story: This is the mkII version of the Twi'lek Chir'daki, or Deathseed fighter. As the New Republic became stronger, Ryloth wanted to upgrade the Chir'daki to a more powerful fighter. The pilots still wanted all of the visibilty and manueverability they had in the mkI's, but they needed more firepower - in particular, they wanted proton torpedoes, which were in very short supply when the mkI's went into service. So, they comissioned Incom to produce the mkII. It carries upgraded engines, ion cannons (where a TIE would have lasers), four wing laser cannons, a torpedo launcher, and an ion cannon. The ion cannon was a big plus, as the Twi'lek forces are as much police as they are military. Incom also added an astromech to help out with the improved hyperdrive, as well as some of the other upgraded weapons.
The MOC: Have you seen the Chir'daki mkI? The rotating ring is a LEGO nightmare. So, what you see here is a true integration of X-wing and TIE. I did reduce alot of the size of the structure for the gear housing for the workings of the s-foils (X-wings). I also swept the wings backward, unlike the X-Wing, where they are swept forward.
Nice intergration of the TIE and X-Wing. I especially like how you kept the wing movement from the redesigned X-Wing set. The colours are fairly nice too, although I think the front area could use a bit more streamlining. One thing is still left to be desired: Image size. It would be much nicer and easier and quicker to view a 640x480 or even 800x600 image than these. Again, nice integration of two ships. - John.
