Very nice, I love the fin detail, well done.
I'd probably do streamer as well. I've used the cheap plastic material, but I like mylar better for streamer material. It seems offer better visibility as well.
Oh, what does everyone due for recovery? Estes included a 18 inch long piece of 1/8th rubber that you attach via the tri-fold paper method and a 12 inch long streamer that is 1.25 inches wide that they have you tape to the 1/8th inch rubber. That was for the donor Hi-Flyer kit. Is that pretty much the standard for rockets this size?
