Section A., paragraph 2., subparagraph (c) in this document, as best I can tell: http://www.modelaircraft.org/files/105.pdf I misspoke on the 100 mph limit, and corrected my post. We honor the 200 mph gas turbine rule. The main thing is we try hard not to ruin the good deal of getting to use this field...4000 x 150 ft runways, 18/36 and 9/27.

This said, I have no desire to start another raging back-and-forth about 'advisories', 'rules', 'regulations' that may or may not exist, that have been debated lately ad nauseum in numerous threads.
