Austria-based Rotax is displaying a new engine mockup at Sun ’n’ Fun 2016. The engine block looks a bit like a 912iS, the company’s flagship fuel-injected powerplant, which is currently flying in more than 70 different aircraft models. A total of more than 1,000 engines are in operation, according to Rotax business manager Marc Becker. The new model has several significant differences that could make it a breakthrough engine for the company.
