Boy, if these planes aren't popular, you guys sura had me fooled.

From what I can gather from the Classic Pattern forums, the Mach 1 has to be the most popular design of all, and it's supposed to be SPA legal. But if you say that this design is not popular in SPA contests, who I'm I to argue? Maybe all the fans have been busy building Mach 1's for SPA (you know, with .91 four-cycles, tail dragging gear, etc.) and they'll start appearing next year.

I recently saw 4 pic's on another thread. They were clearly from one of the SPA contests. The four planes pictured were a Compensator, what appeared to be a Phantom I, and two separate Intruders (i.e. not the same plane). These were all designs associated with the start of the "ballistic" era. Go figure!

Oh! And by the way. I believe that the Deception and the Phoenix 8, both of which appear in the SPA list of allowed planes, were designed and flown AFTER January 1, 1976.
