Those were some rockets I made and shot off a week ago. All were experiments, and I'd say they worked pretty well. I still have lots of work to do though. For PGI I'm thinking a short whistle motor with heavy Ti tail, then a standard BP motor with no metal in the tail, then a Stinger third stage, again heavy metal tail. I can't decide what metal to use yet though. Al would be safest and nicest on the tooling, but FeTi or Ti would make a much more visible tail, which will be especially important since it will ignite at such a high altitude. Also I may add a small dark report charge to remove the stick from the BP motor to avoid a dangerous lawn dart. We'll see.
Time for testing.
