Amazing work Matt. I'm going to take this on myself after seeing your amazing work!
A couple of questions, on the piece with the teeth where the rocket goes into the jetpack (pic jetpack009), is that foam core also? How in the world did you do that?
Also, did you use a combination of glue and tape to bond the thin plastic? It seems like it would be very hard to bond because it's so thin. How did you get a smooth surface on the vertical seems of the cones?
Thanks in advance!
