RE: Some early digital proportional history
Highplains,
I used to fly one of those Kraft single stick radios, every component of the system was gold anodized. The stick you are referring to was a aluminum rod drilled and tapped then attached to the assembly. As I recall it was maybe about three inches long, rounded on the end and anodized red. Got pretty good at coordinating rudder and aileron. Now that I think about it, the stick was probably one of the type used on the two stick radio but without the thumb grip. That was for the guys converting over from reeds who would fly proportional with their thumbs. Orbit did it right with the three axis single stick control. Finally, Kraft introduced the three axis stick with the introduction of the Gold Medal system in 1968.
