   I've posted our Boosted Dart R&D report on my web pages.  Comments are
welcome both on content and presentation.  You can find it at:

   Here's a look at what its all about (the report's abstract):

"An experimental program was conducted to investigate the potential of
achieving an altitude performance advantage from a boosted dart over an
optimized conventional single-stage model in the same total impulse class.
Theoretical considerations were addressed that considered design parameters
that result in a predicted altitude advantage for the boosted dart
configuration. A highly successful, safe, and reliable delay timing and
ejection mechanism was developed for the dart which allowed empirical flight
testing. 

"Flight tests results demonstrated an average twenty percent altitude
performance advantage for the boosted dart over the optimized conventional
single-stage model. Graphs and tables are provided that address boosted dart
design parameters applicable to different engine classes for modelers who wish
to conduct future boosted dart research. A perspective on the limitations of
the dart delay timing and ejection mechanism within the restrictions of the
U.S. Model Rocket Sporting Code is presented, as is a request to model rocket
manufacturers to develop prepackaged mechanisms so that all modelers can take
part in the boosted dart experience."

Before you send me UCE, I know what you're thinking...  Did he complain
to five or six postmasters last month?  Now, you must ask yourself one
question: "Do I feel lucky?"  Well, do you, punk?
