Fox model airplane engines had a reputation for ruggedness and contest-winning performance, but were also notoriously difficult to get started - at least without an electric starter. In 1961, when this full-page advertisement appeared in American Modeler magazine, electric starters were not in many modelers' field boxes, and particularly those owned by youngsters whose modeling budget came from meager allowances and paper routes. Born in 1958, I was 15 or 16 years old before being able to afford the luxury, and I remember relentlessly flipping the propellers on my Fox 15 and Fox 35 control line engines. Half the time when they started, they were running backwards and had to be stopped with a rag thrown into the prop, then the process started over again. Ugh. ...but I digress. Fox prided itself on their use of Meehanite iron for the piston. Per Wikipedia: "Meehanite is a trademark for an engineering process to make a range of cast irons produced under specific and carefully controlled conditions to precise internationally recognized specifications. According to the Meehanite Worldwide company, when correctly followed the Meehanite process will produce cast iron with uniform soundness, consistent physical and mechanical properties and dependable performance in service." I don't know what the difference is between the standard Fox engines and the "X" series. My Fox 15 and Fox 35, which I still have, are the standard non-X variety.
