Hi all- a few months (years?) ago, I stumbled on RDS as a once-in-play vendor of some seriously impressive looking HPR kits. It seems the site link I stored has gone bad (http://www.rocketdynamic.com/), and one reference I can find to the company echoes my exact interest- the NorthStar 2-stage at John Coker's page (http://jcrocket.com/northstar.shtml). Has anyone got a bead on the current status of RDS's products? Have they been purchased by anyone? Are plans available in the public domain? As I recall, they had some truly impressive models, but I don't know how technologically advanced they were. Would like to have a chance to tackle them again 20+ years after their launch to see what we can do with the tech we have today. Also, as maligned as they are here, K&S had some awesome designs that would be terrifically fun to clone...any plans available for any of those non-existent kits? Is that considered pirating?
