Nice job on the Goonies Craig. I have a couple of questions for you about school yard sounders. What are the qualifications for a rocket to be considered a school yard sounder? Also what is the minimum altitude that a rocket should attain before ejection? About 100' ??

Here is a new design I call the Arrow Head. Its more of a modern broad point tip style than an native indian arrow head. Looks like I really need to make a Semroc order and get some of Carl's cardstock. After e-mailind Carl I need to break my old habits of estes tube and centering ring ## and memorize the Centuri ##. Very Very confusing??

Thanks Again and Enjoy, JP
