Perhaps because armature space was never at a premium in the larger bodies, the pancake-style motor has seldom been seen in 1:32 or 1:24 scale cars, though Aurora did use the design in its short-lived line of 1:48 scale slot cars.Graham, Thomas "Greenberg's Guide to Aurora Slot Cars", 1st Ed. 1995, Greenberg, USA. p. 27 Since 2002, the pancake motor is found primarily in the reproductions of the 1960s and '70s Aurora HO chassis marketed by Johnny Lightning, then Auto World.
