Model Forum / General / Rockets / September 2004

A week or so ago, someone posted a message about the legality of launching
model rockets in their city's parks (in OR, I think).
So I got curious and called Phoenix Parks and was told that they are NOT

at them now in sun light, the clear has dulled the gloss the paint had had

The place that has been selling the Venus Probes dirt cheap may be
having a final blow-out of them.  This is the lowest per-unit price I've
seen yet, and there are over 1,000 available (in lots of 30).  They are

Somebody MUST know if there's any reason not to use Minwax wood hardener on
balsa fins prior to glueing them to the BT.
