When the lord of the Dark City calls- I answer! I'm not sure exactly what your looking for though but I take it your looking for an instruction set. Unfortunately I don't have the instructions for the Warp Hunter, but I can walk you through assembly as best I can.
The turret goes on just like any of the Wave Serpent, Fire Prism, or Falcon turrets. However you do need to glue it in place. I also recommend pinning the warp hunter's cannon, but don't glue it until you've prime and painted it.
The spoiler fits over the falcon's rear-hatch can be a pain if its doesn't fit initially. But like all forgeworld, a little hot water goes a long way. In fact after just a little water-bending the thing pretty much snaps right on, and hardly needs any glue at all.
Not sure if this is what you are looking for in terms of advice, but hit me with as many PM's as you like, or continue to post in this thread, and I'll check back throughout the day and help in anyway I can. The Warp Hunter is one of my favorite models, so I'd love to help you get put together proper.
