The "De Dion 1903" from Classic Motors is a detailed 1:4 scale copy of one of the first car engines built in large numbers. It has good torque at low RPM and is a very good choice for a scale car of this period.

This slow running 17cc fourstroke engine has an automatic inlet valve and an exhaust valve operated by a single cam. It runs excellent on 2-stroke mixture and can be used with spark ignition or glow ignition.
