ABSTRACT:
A servo-wheel for use in a control system for model craft having a servo-motor and movable control members. The servo-wheel is a rigid disc having opposed planar surfaces. A hub is at the geometric center of the disc and includes a bore extending through the disc. A raised portion protrudes from one of the planar surfaces and forms a first part of the hub. The raised portion also defines a first part of the bore having an inner circumferential surface of a first diameter. A keyed receiver is formed in the inner circumferential surface of the raised portion. An insert is mounted in the disc to form a second part of the hub. The insert defines a second portion of the bore and has an inner circumferential surface of a second diameter, less than the first diameter. A keyed driver is received by the keyed receiver. The keyed driver is rotatably connected to the servo-motor at one end and attached to the servo-wheel hub at the other end, so that the servo-wheel is rotated by the servo-motor. Control rods or a cable interconnect the servo-wheel and the control members so that movement of the servo-wheel is transmitted to the control members.
