RE: History of Senior Telemaster
I started R/C with my Dad in 1969 (Heathkit GD-19, Falcon 56 and ST G.23R/C) and it was rare to very rare to see any reeds at the flying field. I think the digitial Proportional revolution was well underway by the late 1960s.
I remember going to fields in the early to mid 1960s and all we saw were reeds or single channel gear.
