Thanx for the reply! Glad to hear you play 40k. I have not played as of yet (just got my opposing force of nids in the mail), but I'm more into the building of things than the game. I started with LOTR, moved on to WFB, and have had some IG stuff for quite a while. Be sure to check out my tank in another post!
I have made the cockpit out of foam, and then made it again when I realized 2 AM calculations are futile. So with the right sized shape made Im looking into sheathing it in v thin styrene (hmm hope I have enough on hand). Since the pink foam I used was not thick enough I epoxied two cuts together to form the blank. Epoxy does not eat the foam (at least the kind I have) and holds like a tiger! So I see many trim, epoxy, wait sessions in my future. I think I may have also solved one of my problems for some situations. By using thin styrene I wont have to worry about the joint angles as much.
Here are a few wips....

First is my fuselage. This is actually a syringe container which was close enough to the shape and size that I could not pass it up. Next is the tail. Then the cockpit shapes, the first try and the right sized one. Lastly is the turbine in progress. Once I finish the fins Ill squash them down one by one and weld. Ill be adding a rim cap to that. I'll drill a hole in the center, chuck in a drill, clean up the circumference, and fill the gaps with wood putty.
So far so good, I can say that now cuz all the cussing and spitting is over up to this point, lol.
