I started with the Orbit 4 channel in 1970 with the PS-4 servos before switching to a Kraft "salad bowl" in 1971. Sold the Orbit for enough to buy a new Kraft 70 series along with a Logitrol 7 and a 3 channel Cannon from a guy selling out. I bought another Orbit last year and may do the 2.4 conversion like you did John. While I have dozens and dozens of radios now, you never forget how beautiful the first one was or how hard it was to get it.
