Ringmaster, Scientific Stunt Master, and my ears still ring from a short period (4 flights) pitting for a Dyna-Jet. Johnson .35 (Still have one or two). Some there I had, some I just wished for, like the Enterprise Twin Terror. Still have a Berkeley (curtis A-12) and an Enterprise (New Era) kit, as well as an NIB Sterling Ringmaster S-1 kit in my to do stock. And some I was really too young for when they were available.
