Summary of Rule Changes 1998-2007

There are also International Rules Committee (IRC) Rulings about what is legal and what is illegal under 505 class rules.

From time to time the IRC grants measurement dispensations.

Note: the versions on the Web incorporate rule changes since the last printed version of the rules was produced in 1997.
