With the birth of aeromodeling at the beginning of the last century, early pioneers immediately began to cherish the dream of being able to power their models with internal combustion engines. For many years, however, except for some sporadical attempt, the dream remained as such. The breakthrough finally came in 1933 when William Likens Brown, a young lad from Philadelphia who after four years of study and experimentation put the first true model aircraft engine on the market: the "Brown Jr." From then to the present day, model aircraft micromotors have undergone a great deal of evolution. After the "spark" engines, with electric ignition, came the self-ignition ones, but above all, in 1947, the glow-plug engines that still dominate the scene today, together with larger gas engines, in the various two-and four-stroke versions. Single and multi-cylinder, boxer, in-line, radial and even rotary model aircraft internal combustion engines are now a large family that you will find illustrated in detail in this guide. History, evolution, technical characteristics, curiosities... Definitely one of the most comprehensive publication ever published.
