In the past couple weeks I was able to find some spare parts in my garage to build an interstage coupler for a two-stage build. I was originally planning on building a P to N motor two-stage but figured I should probably slow down and take smaller steps. The first build will primarily be to become familiar with my design and equipment as well as using head end ignition. I’ll have more later but for now here’s the booster section from “Unoriginal” and the fincan from “Shovel Ready”. I’m actually trying to keep this flight fairly low in altitude as it’s more of a test build than an altitude attempt.

    Awesome looking rocket as always. Look forward to seeing the flight report. I take it the full scale be using that 6″ motor you mentioned in another post.

    Thanks. I took it out to the desert today to fly but the weather wasn’t cooperating so I scrubbed the launch. Yes, the full scale booster will be using a 6″x60″ motor with a 1/8″ wall.

    That’s too bad, but I’m sure the last thing you want is any weather to influence the flight trajectory. For recovery are you utilizing a line cutter for both stages? I know you have a lot of experience with this method and I can see its benefits in a two-stage application.

    Yep, the recovery area at FAR is good but not Black Rock good, so I’m less inclinced to risk everything when the wind is up. I’m using line cutters for both the booster and sustainer.
