Semroc Plan - Cyber III Gallery

To the best of my knowledge, this was never a kit. It was a Semroc plan from the old days. It intrigued me so I wanted to build it. It was my first, and thus far only, traditional three stage rocket. It has flown several times in single and 2 stage mode. I finally got the nerve to try it with a full stack of wimpy motors. IIRC, it was B6/B6/1/2A6. That was still too much. I have the two booster stages sitting around here and will get around to rebuilding the sustainer one of these days.

Nice build, and good looking, hi-vis paint. It was fun while it lasted, eh?

I had the same experience with a Camanche 3. One stage fine, two stages fine, full stack—sustainer goes missing.
