A steering wheel adapted for replacing a rotatable control shaft-mounted
finger dial of an RC control unit includes a wheel having a diameter at
least as large as at least one dimension of a side of the RC control unit
adjacent to the wheel, a coupler located on one side of the wheel for
engaging the RC control unit, and at least one bore passing through the
wheel. A fastener is positioned within the bore for removably connecting
the wheel to the control shaft of the RC control unit.
