Hey man that looks good, if it is for FPSC tho, i would tend to make just the generator and then make the segments seperatly, it will have better colision that way.
On a side note, Mods, as Asher hasn't asked, can this be moved to the general 3D chat board, just to avoid confusion?
Keep up the hard work asher, your models are definatly improving!
This tutorial might help with converting the model to be FPSC ready, and im sure there is another thread floating around the forums aswell.
Edit:
This tutorial will certainly help

!!
HMMMMMMM
