For those interested, there is still a very active community around Control Line airplanes as well as world championships.

I was the president of the Northwest Fireballs for awhile.

If you are in the Portland/Vancouver area visit Delta park on most weekends and there will most likely be a group flying. If you have the chance to catch a competition at Delta park you will most likely see any number of former world champions.
