9/5/09: Plafit Rabbit, Pointer, Cheetah II RPM and torque from Professor Motor added.
The tach reads the RPM by shining a crimson gentle on a spinning disc on the
motor shaft. 2/6/09: Ninco NC9 "Sparker" and 1/28 XLOT motor added.
They do a good job of evoking the 1940s journey serials the Indiana
Jones movies drew on. Probably the most costly are Indiana Jones and The Statue of
God Ra (wild symbols).
