The aixro XF40 is one of aixro’s engine for continuous power supply. It is now used in various different development applications, such as microlight aircraft and paramotor trikes. Besides the standard configuration, several variations are possible, such as different inlet manifolds. Also, the engine can be mounted in different orientations.
