I don’t recall any from SF. I’m unaware of a model airplane ban. The race series had been going at least 10 years prior to me getting involved. The series did attract entrants from the Chico area, Southern California, Nevada and Utah. IMO it makes sense that it is quite popular, of all the classes at Reno not many people talk about any other except for the Unlimiteds. Just something about Mustangs, Spitfires, Bearcats and the like rounding the poles at 170mph. Those YS 115 engines on 40% nitro with open headers really get the excitement going.
