Cloning the Centuri X-24 Bug is really easy - use the nosecone from the Estes Yankee. It is an "Estes-ization" of the Centuri nose cone. I built one and I used foamcore for the bulkhead. It flew great, but it isn't real robust - after five or six flights it started to warp and I need to build a new one.

I really liked the Centuri newsletter (it may be on Jimz) that showed building a Saturn V and putting the Bug on top like a nose cone - the booster came back via chutes while the Bug ejected and glided in.
