This is what I came up with below. I'll tweak it as needed when I have all the parts. (I also ordered a digital Scale to use for this build)



Playing around in Open Rocket again with the Pirate. The tube lengths are guesstimates, the transition and nose cone measurements are from what I have on hand, and the fin dimensions are the best I could come up with from the catalogue drawings. Depending on the time of day and whatever mood I happen to be in at the time, the fins sometimes look like they have a bit of a rearward sweep, so I've twiddled them out with both a 90 degree trailing edge and a something-or-other degree sweep - both sets look like they may be a little long in the span. I'll cut some out later this evening and do a dry fit, see how they look. Both files are below, comments are welcome
