We have called it the Joystick
Bob - probably because that's what it is
The Joy Stick was a Noel Rozelle design and produced in three sizes for 0.049, 0.25 and 0.60 engines. He called them Joy Stick, Super Joy Stick & Super Duper Joy Stick respectively.
The 0.049 version was published in the April 1975 issue of RCM and the 0.60 one in the February 1981 issue. They may have also been produced as kits - I don't know.
These shots are the 0.60 & 0.049 versions.

I built a Super Joy Stick from a kit...sometime around '76... I put a Super Tigre .23 on it...nice flyer. I recall that there was a kit of the little one too, for an .049, but I don't remember who made the kits though?
