I've got no business getting in here, but, what the hey....one of the few events that has come about recently, at least in this area, District VIII, is Profile Stunt. It was once P-40, but, it languished because forty-sized engines, a restriction, didn't fit the bill.
Someone, not an individual necessarily, got the idea of removing the .40 restriction and just called it "Profile Stunt". It took off on its own merits.
Still, someone did do the groundwork, someone(s) did run contests with it. Those contests, having so many entries, flew into the dark of night. It just fit a nitch: there are lots of profiles, all sizes, arf or not don't matter, engine size, it don't matter, nothing matters, other than lots of people have them and want to fly them. Just like fly fishin' you "match the hatch".....
I think these things just happen, like the "Ringmaster Renaissance". But, you must give it a try, which means a helluva lot of work, ala' Mike and Joanne K. You know what I'm talkin' 'bout....
