Just for the Record, and only because this thread is getting more scrunity than it deserves.

The rule book is printed on a three year cycle. The AMA now requires licensing of it's name and logo. There is no such thing as an AMA safety nut, as evidenced on the Fox page. The spinner they produce is called a Fox spinner nut 6503 (same number as before). Strictly a technicality, as far as I am concerned, but does support my statement that there is no such animal. http://www.foxmanufacturing.com/stor...s%20%26%20Nuts ,the fact that there is a link on a retail site advertising the nut notwithstanding. The license to use the AMA logo is now part of the Club Renewal Package, as it has been for the last couple of years.

As of April 29, 2004, there are 21 permits issued to 12 builders for experimental aircraft. My understanding is that a couple of those planes no longer exist. However, since it does show 21 permits, regardless of the existence of the aircraft, I will stand corrected. AMA pdf #531 http://www.modelaircraft.org/templat...-files/531.pdf
