The fly-ball actuator was introduced to R/C modelling in 1951 by Brayton Paul, [5] and consisted of an electric motor and a centrifugal governor connected to a free-running axis that could, with the motor running, pull a rudder control rod by varying degrees. Used with a keyed radio system, this allowed some control over the rudder position by ...
