The SP-55 single-cylinder engine is one of our longest standing engines and comes in different versions. The new version, the SP-55 FI TS hybrid is designed to generate electricity for unmanned aircraft systems. The engine has twin spark plugs and is equipped with a fuel injection system. With this new engine, we want to address users of solely electric propulsion technologies who are looking for an efficient generator solution not only for unmanned flight systems but also for other applications.
