One of the major problems I have with the chasm models is, that it is rather hard to convert the skin file. 
 The models self are easy, but to remain to the original skinfile I have to paint them back again from a side-to-side skin to a qmle skinfile.
 I know there are other methods to do this, but that is not in range of my workstyle.
 
 So 
here is the result of my archivement. As you know Stratos shoots a double ringed sprite.
 For getting that code right I have to lean back on the G-Rail code of Dr.Shadowborough.
 
 So for maintaining your request: no, the code is not finished yet.
