Ray,
Exactly the planes! I remember when I was for the first time a spectator at one F3A competition in a town some 30 miles (50 km) from my hometown, I think it was in summer 1973 or 1974, I was 12-13 years old then. Benny was one of the competitors with one of his Mach 1 plane painted exactly as in your picture, maybe it was the plane in the picture You posted. That event "ignited" my interest in acrobatic flying. I remember Benny flying and of course winning this competition also. I remember this clearly - I was learning to fly RC airplane that summer with a Graupner "Taxi" and Enya 6.5 cc engine, Robbe/Futaba 4 ch RC system. I was learning fast then (no simulators to cheat on!), I know I mastered the Taxi trainer in 2 days practice with an experienced flyer as teacher, and I was in heaven - I was more at the flying field that summer than I was at home and all my money went to buy fuel, glow plugs, props etc.
