R43 NAR S&T Motor Update November 7, 1997
As a service to the rocket community, NAR Standards and Testing is updating
the designations of Kosdon motors on the certified motor list. The
manufacturer changed the designations of some motors based on test data
during the certification process. The motors will be listed by their most
recent designation, with the older designations noted parenthetically for
three years. The motors are certified for use regardless of which
designation is used.

This information supersedes the combined NAR/TRA certified motor list as
published in the November/December 1997 issue of "Sport Rocketry" magazine.
